Hey, nice budget version of Teysa.

Karmic Guide and Reveillark are excellent with the Aristocrat strategy. They can reanimate each other and with a sac outlet they make a dying loop with each other. This loop also lets you reanimate all the 2 or less power creatures in your graveyard with Lark. Adding an aristocrat before or reanimating one during the loop can be a win condition.

Lark triggers Teysa when it leaves the battlefield, if it left the battlefield as a result of it dying, letting you reanimate four creatures. Even without Guide Lark is worth adding because of the interaction with Teysa.

Buried Alive and Final Parting are budget tutors that can setup this interaction. Altar of Dementia is a two drop budget sac outlet that can infinite mill your opponents with Guide + Lark. Or use Dementia in combination with Guide + Lark to self-mill yourself until you mill an aristocrat to reanimate with Lark.

Caves of Koilos , Isolated Chapel , Tainted Field , Ash Barrens , Esper Panorama , Orzhov Basilica are budget Orzhov lands to consider adding.

Good luck with your deck.

Thirsting Bloodlord is a bit too expensive for my taste...

in my (limited) experience with Pioneer, even though it is slower than Modern, it is still too fast-paced for a 4 CMC Lord...

Maybe I should splash some white for Legion Lieutenant ... I could run some Caves of Koilos and Concealed Courtyard s... hmmm.

Hey, nice budget Esper deck. Looks like you're not finished?

In Esper colors you can take more advantage of opponent disruption and you kind of need more of it if you want to consistently cast Chromium, who's seven mana. Control the game more by slowing down your opponents which can give you more time to prepare the game for when you drop Chromium. I think you should stick with Tocatli Honor Guard . In fact I'm suggesting to expand on it. Of course this means cutting most creatures who have an ETB ability.

Chromium doesn't have an ETB ability and there's not very many creatures here who do. In Commander many decks, much more than not, rely on ETB abilities from creatures to get value or even to win. Shutting this off can give you a big advantage. Creatures who exile other creatures or permanents when they ETB are risky because of board wipes. When these creatures die from a board wipe then the exiled card goes back to the opponent. Board wipes are more important for Control then these creatures.

In Commander 26 lands is very low for a Control deck. This is the amount of land you would play in a 60 card Control deck in Standard. In Commander there's a lot more than 60 cards therefore you need more lands because you want to make your land drops each turn. Mana rocks and other spells that can get you lands in your hand or on to the battlefield can help, but even with these cards you need more land. You really want both. There's only 91 cards here; my advice is start with adding 10 more lands and the three budget Signets: Azorius Signet , Dimir Signet , Orzhov Signet .

Budget lands to consider adding:

Cards to consider cutting to add lands/Signets:

  • Fleet Swallower
  • Drowned Secrets
  • Psychic Spiral
  • Psychic Corrosion
  • Thought Collapse

Consider cutting the opponent mill theme? Opponent mill is not very good in multiplayer Commander unless your dedicated to it. Graveyards are a huge resource for so many types of decks in Commander; mill will most likely help your opponents rather than hurt them. I wouldn't play mill unless it's the main strategy of your deck. Playing many wheel effects and having infinite mill combos as win conditions.


Other budget cards to consider adding (some of these are in the maybeboard):

Cards to consider cutting:

  • Final Payment
  • Drown in Sorrow
  • Absorb
  • Deputy of Detention
  • Hostage Taker
  • Conclave Tribunal
  • Shell of the Last Kappa
  • Tome of the Guildpact
  • Dire Fleet Ravager
  • Sphinx's Insight
  • Ob Nixilis, the Hate-Twisted
  • Nightveil Predators
  • Basilica Bell-Haunt
  • Dimir Guildmage
  • The Haunt of Hightower
  • Rise from the Tides

Caves of Koilos allows you to have colourless and black and white mana in one card. Worth considering?

Hey, looks good for your first Commander deck. You haven't finished the manabase? Nice Ugin, the Spirit Dragon :)

What's the max budget for your deck? I ask because you haven't allocated yet for lands in the manabase. 35x basic lands is not going to work when you want to pay for spells. When playing five colors the manabase and the amount of color fixing you have in your deck is very important. If you don't make these things priority to focus on getting right then your deck will have a difficult time functioning when playing so many colors.

You have a good start by including the budget land ramp spells ( Cultivate , Sakura-Tribe Elder ), but you're going to want a lot more than just these spells for both ramp and more importantly for color fixing. You can build a five color manabase on a budget with basic lands using some dual lands that have interaction with basic lands, Tri lands and other budget lands.

Here's an example:


This example manabase is not ideal by any means, but it's low budget and a starting point for future upgrades. Sunken, Glade or Stream are dual lands that Farseek can search for since they're two different land types. Being able to land ramp with a dual land with Farseek makes Farseek better and helps with color fixing.

A budget manabase like this example can use color fixing from other nonland sources. Signets and other budget mana rocks that can make colored mana and ramp are options.

With Signets you can pay for the colorless mana cost with mana from any source such as a land. That mana then turns into two different colors of mana. For example if you have two Signets on the battlefield and two lands then that mana can be four different colors of mana. In this manabase example there's more green sources than others that's because green is the enabler color to help to get all the other colors with land ramp and mana dorks. There's more green than the rest because you consistently want to have green mana in the early game.

Joiner Adept lets you tap lands for any color of mana which is great color fixing when playing five colors. Chromatic Lantern is a more expensive price card that does the same thing and it's better because it also ramps. Faeburrow Elder and Paradise Druid are called mana dorks and either one can tap to make different colors of mana. Faeburrow by itself can tap to make two mana . With Jodah, Archmage Eternal on the battlefield it can make four mana . If you have Jodah and have a permanent on the battlefield that's black then Faeburrow can tap to make all five colors of mana.

Fertile Ground is an example of another source of color fixing/ramp that's different than the rest. It's an aura that enchants a land you control. When the enchanted land is tapped it makes two colors of mana; one mana that the land could produce and another mana of any color you choose.


Color fixing sources that also ramp are better than ones that don't. If you can as the saying goes "kill two birds with one stone" then it can help your deck. Including most cards that can do two different things you want are better than cards that can only do one thing you want. For example Cultivate ramps and color fixes since it can find two different basic lands. Izzet Signet taps to ramp and color fix two different colors of mana. Renegade Map only color fixes, it doesn't ramp because it only puts the land you search for into your hand not onto the battlefield and it can't tap to make mana.

Sylvan Scrying is one exception since it can tutor (search your library) for any one land and put it into your hand. That's powerful and helpful to have when you can get a land that can make any color of mana such as Command Tower or better yet Cascading Cataracts which can tap along with five other sources of mana of any colors to make all five different colors of mana. This land makes it easy to be able to make five different colors to cast spells with Jodah. Cataracts is good with ramp from mana rocks.

I have suggested a lot of cards which means if you want to include them then you'll have to make many cuts. I'm not going to give you suggestions of cuts now, but if you're interested in any of these suggestions then I offer to help to make cuts. This is the nature of building budget many colored decks in Commander; have to allocate a lot of deck spots to cards to help the manabase and to make sure your deck can function, so you can reliably cast cards. Good luck with your deck.

Hey, fine budget version of Kaalia and nice description/primer.

Manalith, Mana Geode, Boros Cluestone, Rakdos Locket, Orzhov Locket, Armillary Sphere, Star Compass. Consider cutting these for better budget mana rocks?

The main purpose of playing so many mana rocks is to ramp into Kaalia. Two drop mana rocks are better than three drop rocks even if the three drop rocks can be saced later on to draw. The draw from Lockets/Cluestone is not worth playing them over a Talisman or Signet as a Talisman or Signet can give you a full turn or two faster at casting Kaalia.

More haste enablers is another way to increase speed.

Out of these budget options Tempest is the best because Kaalia has flying and all the other big creatures here also have flying. Tempest is also very good with Utvara Hellkite and her ability to create Dragons. Battlements is a land that can ETB untapped which for one red can give Kaalia haste.

For more speed then you want most of your lands to ETB untapped. If you can't afford many dual lands that ETB untapped then play more basic lands instead of lands such as Forsaken Sanctuary, Stone Quarry, Bloodfell Caves, etc. Signets are good with basic lands because any one basic land can be tapped to make two different colors. Budget lands to consider adding:

If willing to spend a little more for the manabase then adding the Check lands: Dragonskull, Isolated, Clifftop are good lands when playing basic lands.


Cards to consider cutting:

  • Forsaken Sanctuary
  • Stone Quarry
  • Bloodfell Caves
  • Scoured Barrens
  • Wind-Scarred Crag
  • Painted Bluffs
  • Seraph Sanctuary
  • Manalith
  • Mana Geode
  • Boros Cluestone
  • Rakdos Locket
  • Orzhov Locket
  • Armillary Sphere
  • Star Compass
  • Trailblazer's Boots
  • Hoard-Smelter Dragon
  • Desecration Demon

Cheap cards u should get some amount of:

General value goodstuff:

Bloodsoaked Champion

Grim Haruspex

Midnight Reaper

Ophiomancer

Zulaport Cutthroat

Westvale Abbey  Flip (you're gonna love this one, it's especially good if you like having token generators)

Skullclamp (probably the most powerful equipment in the game. And drawing cards is fucking awesome)

Removal:

Swords to Plowshares

Plaguecrafter

Kaya's Wrath

Anguished Unmaking

Grave Pact

Reanimation (very good when you're actively putting cards from your deck into your graveyard):

Dread Return

Karmic Guide

Reveillark

Phyrexian Delver

Liliana, Heretical Healer  Flip

Victimize

Animate Dead

Sac outlets:

Viscera Seer

Carrion Feeder

Cartel Aristocrat

Yahenni, Undying Partisan

High Market

Tutors:

Ranger of Eos

Diabolic Intent

Enlightened Tutor

Beseech the Queen

Dark Petition

Mausoleum Secrets (very cool in your deck)

Lands:

Orzhov Basilica

Scoured Barrens

Concealed Courtyard

Command Tower

Caves of Koilos

City of Brass

Isolated Chapel

Tainted Field

You should probably choose whether you want the deck to be more or less focused on tokens. If you don't want tokens to be a main theme, you should probably just run Ophiomancer and a couple other generators and put in more reanimation effects like Phyrexian Delver .

You should still run Karmic Guide and Reveillark no matter what you do because they're too good not to. With a sac outlet, you can sacrifice them and bring them back an infinite number of times and kill your opponents with Komrade.

I would run quite a few sac outlets to make sure you can keep sacrificing your stuff for value. The best ones are Viscera Seer , Carrion Feeder and Cartel Aristocrat . Skullclamp works especially well with sac outlets

Hey, good job for your first Commander deck. Nice Tezzeret the Seeker :)

When on a budget for the manabase it's better to rely on basic lands and dual lands that have interaction with basic lands. These can replace dual lands that will always ETB (enter the battlefield) tapped such as Azorius Guildgate and Dismal Backwater . The Guildgates and Life lands are not better than a basic land.

Lands within the budget to consider adding:

Land to consider cutting:

  • Azorius Guildgate
  • Dimir Guildgate
  • Dismal Backwater
  • Scoured Barrens
  • Tranquil Cove
  • Jwar Isle Refuge
  • Vivid Creek
  • Dimir Aqueduct
  • Temple of Deceit
  • Temple of Silence

I see too many creatures that don't interact with Alela. Nonartifact/enchantment creatures don't have much interaction with Alela. My advice is cut a lot of these creatures for more artifacts, artifact creatures and enchantments. You have Tezzeret that's a good reason to expand on artifacts.

Lots of mana rocks are good with Alela because they can be used to make ramp to play her faster and then after she's on the battlefield they can create Faeries. I see you have the Signets already which is great, but consider more budget mana rocks?

Three drop mana rocks such as Coalition Relic which you have are fine, but if you can replace a three drop mana rock such as Obelisk of Esper , Mana Geode with a one or two drop mana rock then this will help your deck.

Consider cutting the creature base down to only a few? Keep: Strix, Architect, Shimmer Myr, Simulacrum, Assembly, Master, Seer, Rider, Titan? Can then replace the other creatures with more artifacts/enchantments to make more interaction with Alela.

Cards within the budget to consider adding:

Etherium Sculptor and Foundry Inspector are good as low mana cost artifacts that reduce the mana cost of all other artifacts you cast. CMC artifacts are free for you to cast with one of these on the battlefield which can help to chain cast artifacts and make a lot of Faeries. Casting two drop mana rocks for is also good. Sai, Master Thopterist and Mirrodin Besieged are three drops that any artifact you cast after creates an artifact creature token.

If you're wanting to attack with a large Faerie/Thopter army then Bident of Thassa and Cranial Plating are cards that you want. Bident can be busted repeatable draw with attacking flying creatures. Cranial is good to equip to Alela since she has flying and the damage she does to a player is Commander damage. Throne of the God-Pharaoh is a deceptively powerful two drop artifact with Faeries. The life loss this can do will add up fast since it's repeatable at your end step making all your opponents lose life not just one.

Good luck with your deck.
