lol this deck is awesome and super fun to play!!!

+1 upvote from me!

gingerthewritingdog Thanks! Appreciate it! :)

Fellow 5c Mutate player here.

I like what you got going here, but I wonder how you fare in terms of card draw. Also, how has Cromat been working for you? I can see it might be a bit mana greedy. Have you considered Jegantha, the Wellspring at all?

+1 from me. :)

Phaetion: Thanks for the +1! This is my online brew (waiting for paper to be released) so I haven't really tested it much other than playtesting on tappedout. From over 20 playtesting games by myself here I think that Cromat is a great target to be mutated on since he kinda protects himself so you don't get 2-for-1 that often. Its regeneration and ability to put himself on top of the library is very useful but I don't see myself spending much mana to activate its ability often till mid to late game once my board is established. I also run a significant amount of ramp and usually have a ton of mana by turn 6 so I've never run into any issues with mana.

Jegantha, the Wellspring has definitely came across my mind but its not a great target for mutate since it can only ramp and doesn't protect itself. I could see myself eventually testing it out in the 99 instead. As for card draw, out of 20 playtesting games I've only have 4 games where I kinda ran out of gas but that is remedied with the inclusion of cards like Bonders' Enclave and Urban Evolution. Sylvan Library is also pretty gross in this deck since there are so many ways to gain a ton of life like Majestic Auricorn to let me draw 3 per turn essentially. There are also a surprisingly good amount of recursion mutants and my favorite so far is Lore Drakkis which is broken with cards like Demonic Tutor or Cyclonic Rift.

Have you thought about Cephalid Constable

sam171z: Yeah the only problem is that it is too fragile and a huge target for removal. I want to try to include more hexproof creatures so that I don't get totally blown out but a single target removal.

Hi, Nice deck. As I live in China (Ikoria released in paper last month), I've been playing my 5c mutate deck for awhile now. My playgroup has allowed me to use Surgeon General Commander. It's done quite well and mutate is a lot of fun.

You are right about hexproof. I recommend adding Slippery Bogle and Gladecover Scout. They are great bases for mutate.

Dom171: Yeah, I'm gonna start cutting out some of the more clunky mutate creatures to make room for the hexproof creatures.

This decks looks really fun!! I have a question about Cromat 's ability + Sylvan Library /Vivien, Monsters' Advocate. Could you please explain this ability a little more in depth as to its advantage? Also, how exactly do Planeswalkers and the mutate ability interact exactly? Sorry for the headache.

This list is awesome, man! Defintely adding in two colors to my theoretical Mutate deck. Also, how does Oko the Trickster work with Mutate?

WarSpaniel: So basically Sylvan Library allows you to draw two additional cards so if you put Cromat and the mutated creatures on top you can draw them all again. Vivien allows you to cast creatures off the top of library so you basically don't lose any card advantage by putting Cromat on top. Planeswalkers are basically unattackable when mutated on.

52piggy: After you turn Oko into a creature, you want to mutate on top of him. The result is a mutant walker hybrid that cannot be attacked. Each turn you can tick up your mutant and add 2 counters to it, until you can ult it and it becomes a 10/10 with all those counters. As long as the mutant on top isn't legendary, you can also clone this mutate pile and get multiple planeswalking mutants.

I also want to add that even though Oko was turned into a creature, he can still activate his loyalty abilities. I know this is strange but I've checked with multiple judges and it definitely works (see Gideon/Experiment Kraj rulings).

Thank you for the quick response I really enjoy looking at your decklists. However, I’m still a bit confused. For example, someone tries to remove a mutated Cromat. You activate his ability and put the mutated creature pile on top of your library(in any order correct)? Next upkeep Sylvan Library triggers and you draw Cromat and the other creatures. I’m not understanding how you’re getting ahead on cards.(I’m really sorry to bother you). Could you please clarify a little more?

WarSpaniel: Well I guess that only applies if there's only one mutated create on Cromat since you'll be drawing an extra crad with Sylvan. But what I'm trying to get at is that it reduces the setback of putting all of your mutants on top of your library. Since most mutants generate card advantage by themselves via mutating the ability to re-mutate them again is gaining card advantage.

I see thank you for your patience with this question. Do you know if you choose the order in which you put the creatures back on top of your library using Cromat’s ability? Also, that planeswalker interaction seems pretty busted. Does the Planeswalker need to be on top of the pile in order for the interaction to work as you described?

In the above description on mutating on top of Oko, can you still attack with the creature?(it just has loyalty abilities in addition to any of it’s creature abilities. Also, would standard creature removal still work on it?

So, to make this better, you can just make room for creatures with undying/persist by throwing out most of the things that aren't lumbering behemoths on their own. Undying/persist is really great with Flayer of the Hatebound. Undying works better because of a really funny synergy with Marchesa, the Black Rose. Mutate onto the undying creatures. All creatures in a mutation pile come back at the same time, but they won't be attached to each other. Your voltron strategy now becomes a battlecruiser strategy. If you have mutations left to perform, you can mutate onto the pieces of your now disassembled creature. I think that giving your deck the flexibility to change strategy on a dime and not lose hardly any steam at all could help the deck perform even better than it does already. This idea could just let you outpace your opponents very, very quickly.

Um, I just noticed... Bassara Tower Archer is a human, so...
