How good is mutate in Commander. With so many mechanics in Magic: The Gathering, it can be hard to even remember them all, let alone judge them and weigh them against one another. One of our favorites though, comes from Ikora: Lair of Behemoths. The set has a lot of fun stuff within it, including the likes of Godzilla, but we really want to hone in on one specific mechanic.
We are, of course, talking about the mutate mechanic, which allows you to constantly change up the rules of your own creatures as you see fit, just as long as you’re not using Humans in your deck. We’re not sure why you’d use Humans anyway, they’re a bit dull from a flavor perspective, even if they are powerful. Anyway…
What is mutate in MTG?

Mutate is a mechanic that changes how you cast your creatures. It reads, “If you cast this spell for its mutate cost, put it over or under target non-Human creature you own. They mutate into the creature on top plus all abilities from under it.” Often, the mutate cost for a creature will differ from the standard cost, and more often than not, the cards with this mechanic will have triggers that occur every time they mutate.
Just take
Nethroi, Apex of Death
Nethroi, Apex of Death
Mutate {4}{G/W}{B}{B} (If you cast this spell for its mutate cost, put it over or under target non-Human creature you own. They mutate into the creature on top plus all abilities from under it.)
Deathtouch, lifelink
Whenever this creature mutates, return any number of target creature cards with total power 10 or less from your graveyard to the battlefield.
as an example, which has this ability: “Whenever this creature mutates, return any number of target creature cards with total power 10 or less from your graveyard to the battlefield.” In short, you’re going to want to stack your deck full of mutate cards and then have them all interacting with one another.
There are two limitations to this mechanic. For starters, there are only 39 cards that include the word mutate on them, and one of those is silver-bordered. Plus, they’re across all five colors, which leads to the other issue, which is that there is no one single commander that can have all of the cards in, or at least not one that has mutate on it itself. As long as you’re fine with running, let’s say
Morophon, the Boundless
Morophon, the Boundless
Changeling (This card is every creature type.)
As Morophon enters, choose a creature type.
Spells of the chosen type you cast cost {W}{U}{B}{R}{G} less to cast. This effect reduces only the amount of colored mana you pay.
Other creatures you control of the chosen type get +1/+1.
, then you can pick and choose from the mutate cards on offer.

You’ve also got cards that don’t have mutate themselves, but do give you bonuses when doing so.
