Hey there! No problem, and you have definitely come to the right place! Here are some types of lands that I personally think should have a spot in every deck, and some multi-colored lands that work anywhere and everywhere! I hope this helps you throughout your journey in the world of magic.

These dual lands are some of the best, and my favorites, though there are many more people enjoy playing, such as bounce ladnds (Dimir Aqueduct), Battle Lands (Sunken Hollow), Reveal Lands, (Port Town), Cycle Lands (Irrigated Farmland), Storage Lands (Calciform Pools) and many others, but usually you don't have this many spaces in your deck, and so the ones I named first are usually better. However, I'm not done! There are many multicolor lands that fit in any deck, that are extremely powerful! Some of them are listed below.

So Enlightened Tutor comes to mind. I think it's probably better than Idyllic Tutor, though it's significantly more expensive. If you're working on a budget, Idyllic Tutor is perfectly okay.

Toxic Deluge is an expensive card that I expect to go down in price soon (it's been reprinted in Double Masters, and in my experience masters sets tank their rares, if only for a short while). It'd be especially good since you have a lot of high-toughness cards.

I think Mythos of Nethroi is probably better than Putrefy.

I also think that even in a deck based on walls, you can benefit a LOT from one-mana mana-dorks. Arbor Elf, Elves of Deep Shadow, Elvish Mystic, Llanowar Elves, Deathrite Shaman, Fyndhorn Elves etc. will accelerate you in a way that only green can do. Even with boardwipes, they're worth it. Note that they also let you land your general turn two, if you get the right mana.

Additionally, since you're not a landfall, I feel like you're running too many lands. Replacing some with dorks will let you come out of the gate a lot faster. (I play EDH with a lot of more powerful decks, and your experience may differ from mine. However, I find that being able to land a meaningful turn-one play like Birds of Paradise is good in all power-levels.)

Speaking of lands, your mana base can be improved for relatively cheap. Indatha Triome is about $4 these days, and could easily replace your Jungle Hollow... Fetches are busted, especially when paired with duals like Overgrown Tomb or Savannah. However, if you don't plan on selling a kidney, there're other ways to improve. Slow-fetches (Rocky Tar Pit, Bad River, Flood Plain, Mountain Valley and Grasslands) are super affordable. Note that they can also fetch your non-basic typed lands (like Canopy Vista or Indatha Triome). Other lands of various prices to consider are Exotic Orchard, City of Brass, Reflecting Pool, Llanowar Wastes, Brushland, Caves of Koilos and friends.

Card advantage decides most EDH (and Magic in general) games. Some cards to consider: Sylvan Library, Painful Truths, Harmonize, Night's Whisper, Phyrexian Arena, Dark Tutelage etc. are all good ways. I was going to suggest Runic Armasaur, but you already spotted that one.

Retribution of the Meek is a GREAT wipe for decks like this.

I also suggest cutting some cards. I don't think Path to Exile is very good in EDH, where one-for-ones need to be REALLY good (like Swords to Plowshares or non-type specific like Mythos of Nethroi), and Path to Exile ramps your opponents. They're very likely to just use the extra mana to deploy a more dangerous threat. Glyph of Doom is interesting, and might be good, but I don't think it would be (granted that's not based on direct experience). I think you could probably just use a more powerful card in that slot. I also think you can cut some of the equipments for more influential cards. For example, if you cut Spidersilk Net and friends you can run things like Collector Ouphe and Stony Silence. If you're running mana dorks, you'll have ramp while your artifact-based friends get nailed.

Right. That's all I got. Hope this helped!

Bats! referencing Caves of Koilos:

Koilos Colony Mother

Creature - Bat

Flying

Other Bats you control get +1/+1 and have lifelink.

2/2


I'd like to see another lord with mana cost either or and is a 2/2

I'd recommend Stoneforge Mystic and Silent Clearing.

City of Brass, Caves of Koilos, and Mana Confluence are also possible land choices, but you'd know better than me if you need them.

Hey, good start upgrading the precon on a budget.

28 lands is not enough land for an avg. CMC of 3.4 which is high. I recommend 36 lands and adding Knight of the White Orchid. First strike with a two drop Human is good with +2 pump from Jirina. You want to take more advantage of Jirina who's a four drop anthem effect for Humans. This means you want to consistently be able to play more impactful one drops (Champion of the Parish)/two drops (Thalia's Lieutenant)/three drops (Frontline Medic) to attack with the turn you play Jirina.

Tribal creature strategies in Commander fold to board wipes. To combat this play more repeatable instant speed indestructible protection (Etchings of the Chosen), creature recursion (Phyrexian Reclamation), reanimation (Alesha, Who Smiles at Death) and noncreature repeatable sources of Humans (Outlaws' Merriment).

Hey, good budget version and interesting description. Nice Demonic Tutor :)

Cards $2 or less each to consider adding:

You want more protection for the creature you mutate too because without protection the mutate creature can be killed in response to being mutated or after. In multiplayer Commander mutate is much more of a problem because there's three or more opponents who could have removal. That's a lot more potential removal you have to deal with than if you were playing 1v1.

Swiftfoot Boots gives the equipped creature hexproof meaning that creature can't be targeted by your opponents removal. Boots is an equipment, it can be equipped to any creature you control and it doesn't leave the battlefield when the equipped creature is removed. Open the Armory is a budget tutor that can get Boots.


Flying and double strike is a good combination to do Commander damage with Snapdax. Hushbringer is powerful disruption in multiplayer Commander since it prevents all creatures who have an enter the battlefield ability that triggers and any creature who has a dies ability that triggers. These two types of triggers are ways for players to gain a lot of value from creatures. Hushbringer is not going to affect you much since mutating is not an enter the battlefield trigger it's a cast trigger thus Hushbringer doesn't prevent mutating.

Will-o'-the-Wisp is a one drop flying creature who can regenerate. This little Spirit can be powerful with mutate. Brightling is a unique creature with mutate since you can bounce it as well as all creatures that are mutated back to your hand. This is pseudo protection because you can activate Brightling in response to opponents removal. By bouncing all the creatures that are mutated then you can mutate them all again getting more value out of mutate.


When Snapdax dies you can choose to spend it to your graveyard instead of putting it back into the Command Zone. This gets around having to pay Commander tax for Snapdax and the tax must be paid even if you're mutating Snapdax from the Command Zone which can be problematic. When Snapdax goes to your graveyard then you can recur it with cards that recur creatures from your graveyard. Phyrexian Reclamation is very good repeatable recursion at instant speed for mutate creatures because you want the creature to come back to your hand to then cast it again to mutate again.

Cards to consider cutting:

Good luck with your deck.

TriusMalarky on Returning players - where to ...

Since you're just playing with friends, you get the leeway of not needing to spend tons of money acquiring decent cards. That means that, overall, you can get a lot more bang for your buck.

I'll be giving you my personal preferences for a casual player who may or may not ever get into slightly more competitive play, AKA FNM.

  • 1) There are bulk boxes available for $15-20 of a thousand or two assorted cards. Keep in mind a lot of the cards might not be legal in Modern, but they do tend to be acquired from mostly newer sets(from the two I bought, ~70% of the contents were standard legal at the time of purchase). I recommend one of those to just about everyone who's getting into the game. They might not end up giving you tons of great value, but it's solid card fodder to help you learn and explore more archetypes and strategies.

I also recommend picking up cheap staples by the playset. The following are a bunch of cards you can probably get for $2 or less apiece, in many cases for the whole 4 copies.

That's mostly just a pile of suggestions, though. The lands will be absolutely necessary for any multicolor deck you build, although wait a month or three to get the Thriving lands because those currently have an immensely low supply and will be reprinted shortly.

Balaam__ on Orzhov Budget Vampires

Nice build. I’ve been trying to work out the finer details of my own vampire deck for awhile now, and it can be tricky.

One thing I noticed right away about yours is the mana base could be adjusted to better accommodate your white cards. Unclaimed Territory works great for your creatures, but only provides colorless mana outside of that card type. Caves of Koilos is functional, but at 4 copies doesn’t quite provide enough reliability if you happen to have an opening hand with some white cards in it. I’d recommend Cavern of Souls in place of Unclaimed Territory as it’s strictly better, and I’d also remove 4 basic swamps to include Godless Shrine. This will supplement your white mana without forfeiting any black mana in the process. The only real issue with my suggestions is their real world price; neither are exactly budget friendly. The beauty with the lands is that they will most certainly be useable in other builds outside of this one. So I’d consider them an investment of sorts.
