Tyrant-Thanatos on Why is WotC Inconsistent with ...

2 weeks ago

Don't have any stats on-hand. But from what I recall, it all seems to do with rarity. Rare land cycles only get half the cycle. Common/Uncommons can/usually get the full 10.

I understand WotC not wanting to suck up 10 rare slots with dual lands, but personally I'd rather just see them stop printing rare dual lands altogether.

I mean I guess cycles like shock lands at uncommon might be really powerful, but do cycles like Temple of Silence or Caves of Koilos really need to be rares??

Even Fast Lands and Check Lands seem to me like they really don't need to be rares.

Hey, nice budget Dragon deck.

Games where you draw and get Utvara Hellkite onto the battlefield are going to be much better than games when you don't. Consider a few more budget tutors that can tutor for Utvara?

Cards to consider cutting for these tutors:

  • Fated Return
  • Relentless Assault
  • Yosei, the Morning Star

Consider cutting the five Vivid lands replacing them with budget Pain lands? Adding the Pains lands will reduce the number of lands that ETB tapped which can help game play.

Dragon Arch or Elvish Piper can cheat a Dragon from your hand onto the battlefield. Generous Gift and Beast Within are upgrades for a removal spells. Sarkhan Unbroken is an upgrade for a Dragon Planeswalker. Paradise Druid is a budget mana dork who can make any color of mana.

Cards to consider cutting for these:

  • Keiga, the Tide Star
  • Mortify
  • Utter End
  • Darksteel Ingot
  • Sarkhan the Mad

Good luck with your deck.

Hey, nice budget version of Teysa :)

Budget lands to consider adding:

Cards to consider cutting:

  • 3x Plains
  • 3x Swamps
  • Temple of the False God
  • Scoured Barrens

I offer more advice if you would like. Good luck with your deck.

Hey, good first version, nice Avacyn, Angel of Hope :)

29 lands is unfortunately not enough land especially since Tariel is seven mana... The priority for deck changes to consider is to add more lands and add more ramp. I recommend 38 lands and 5 more additional mana sources. You don't just need more lands for Tariel you need them to be able to consistently play the other Angels in your deck since many of them have high mana costs.

Budget cards ($3 or less each, most are $1 each) to consider adding:

Cards to consider cutting:

  • Angel's Feather
  • Scroll of Avacyn
  • Pious Interdiction
  • Angelic Gift
  • Increasing Devotion
  • Syndicate Guildmage
  • Cathar's Companion
  • Angelic Wall
  • Ritual of Rejuvenation
  • Flameblade Angel
  • Angel of Renewal
  • Teyo, the Shieldmage
  • Kaya, Bane of the Dead
  • Replenish

Replenish is an amazing expensive price card, it's great you have it, but it's not doing much here because there's only seven enchantments. Because you have Replenish you should consider building an enchantment matters deck with lots of enchantments.


Other budget upgrades to consider:

Good luck with your deck.

Hey, nice version of Thrasios/Tymna :)

Lots of expensive price cards and interesting interactions here, but the manabase is not good. 17 of the 34 lands ETB (enter the battlefield) tapped which is too many for a $600+ deck. The manabase doesn't match the rest of the deck. The Temples, Vivid lands and ETB tapped Fetch lands are not competitive lands. If you're wanting to improve the casual competitiveness of your deck my advice is upgrade the manabase.

Some lands to consider adding:

These are the least expensive price playable land options in these four colors. In fact many of these land suggestions can be further upgraded with more expensive price lands. Adding a Nature's Lore can also help because it can search for one of Pool, Tomb, Garden or Vista.

Cards to consider cutting:

  • Vivid Creek
  • Vivid Grove
  • Vivid Meadow
  • Bad River
  • Flood Plain
  • Grasslands
  • Gateway Plaza
  • Temple of Deceit
  • Temple of Enlightenment
  • Temple of Malady
  • Temple of Mystery
  • Temple of Plenty
  • Temple of Silence

multimedia on Daxos Enchantment

1 month ago

Hey, saw your forum topic asking for help.

Nice upgrade of the precon, but consider less creatures, more one and two drop enchantments? Lots of creatures is not really needed because Daxos is a repeatable source of creatures from the Command Zone. For him to create a token that's worth three mana then you need to be casting enchantments. One and two drop enchantments can give you experience counters faster and also reduce the avg. CMC of your deck.

Ward, Ghostform and Renewal can protect Daxos. Bounce Ward for one mana and then cast it again. For Ward is an engine to get experience counters with Daxos, draw a lot of cards with Mesa, gain a lot of life with Coinsmith, create a lot of Angels with Throne, etc. Conviction can also be an enchantment engine for .

Ascension can be a repeatable source of creatures it's amazing in multiplayer Commander because it looks at each opponents end step. Obedience and Consuls expand on the pillowfort strategy which is helpful to stall opponents, giving you more turns to get experience counters, get other value from casting enchantments and make Spirits with Daxos. Exort is also a deceptively powerful effect in multiplayer Commander.

Hall of Heliod's Generosity from Modern Horizons brings a new graveyard strategy with repeatable enchantment recursion for white enchantress decks (wanting to cast enchantments to get value). You can now use your graveyard as a source of enchantments. Hall has good synergy with an enchantment that can sac itself to give you value such as Seals, Aura of Silence, etc. since you can recur it, draw it and cast it again. Sun Titan is very good repeatable reanimation of 3 or less CMC permanents includes enchantments and lands.

Other budget cards to consider adding:


I'm not going to give you an exact plan of what cards to cut and replace. Instead, I'm giving you lots of options, list of 26 cards to consider adding and list of lots of cards to cut. I'm leaving it up to you to make the decisions of what you cut. My advice of cards to cut are creatures and high CMC cards. Cards that don't give you value right away or repeatable value over time can be cut. The exceptions for these kinds of cards is removal, board wipes and draw spells, but you only want a few of these kinds of cards not a lot instead focus on enchantments.

Cards to consider cutting:

  • Temple of the False God
  • Vivid Meadow
  • Orzhov Guildgate
  • Vivid Marsh
  • New Benalia
  • Herald of the Host
  • Necromancer's Covenant
  • Deadly Tempest
  • Teysa, Envoy of Ghosts
  • Dreadbringer Lampads
  • Treasury Thrull
  • Thrilling Encore
  • Thief of Blood
  • Silent Sentinel
  • Celestial Archon
  • Vow of Duty
  • Vow of Malice
  • Kor Sanctifiers
  • Corpse Augur
  • Burnished Hart
  • Banishing Light
  • Traveler's Amulet
  • Ghostblade Eidolon
  • Nighthowler
  • Orzhov Cluestone
  • Death Grasp
  • Finale of Eternity
  • Ancient Craving
  • Nevermore
  • Marshal's Anthem

I offer more advice if you would like. Good luck with your deck.
