Universes Beyond
TMNT is a smaller release than a full tentpole expansion, and the format reflects that: five two-color Limited archetypes instead of the usual ten. What it lacks in breadth it makes up for with Sneak, one of the more interesting new mechanics of the year.
Everything in the set orbits four themes — +1/+1 counters, creatures entering the battlefield, artifacts, and Sneak — which is how a set this small still holds together across wildly different settings.
Themes
Sneak
Cast a spell by returning an unblocked creature to your hand during the declare blockers step, usually at a mana discount and often with a bonus for doing it. Worth being precise about how it differs from ninjutsu: Sneak *is* casting the spell, so it can be countered, whereas ninjutsu is an activated ability that can't. Ninjutsu also lived on creatures — Sneak turns up on noncreature spells too.
Mutagen
An artifact token. Sacrifice it to put a +1/+1 counter on target creature — which quietly makes every Mutagen-maker an artifact payoff and a counters payoff at the same time.
Disappear
Pays you off whenever a permanent you control leaves the battlefield, which turns sacrifice from a cost into an engine. It anchors the black-green archetype alongside Food tokens.
Alliance
Triggers whenever another creature enters the battlefield under your control. Cheap to turn on repeatedly in a set this dense with token and ETB effects.
Class
The levelling enchantment type from Adventures in the Forgotten Realms, back as a way to represent characters growing into their roles over a game.
Partner — Character select
A Commander-deck variant of partner: it lets you field a second commander, so the precon can put a specific character in the command zone alongside its face commander rather than forcing one canonical pairing.
Limited
A smaller set means five two-color pairs rather than all ten, and each one is built on a single named theme.
Sneak
Instant-Speed Tricks
The archetype that leans hardest on the new mechanic — Sneak creatures used as combat tricks at instant speed.
Alliance
ETB Aggro
Built on the returning Alliance mechanic, so the deck wants a steady stream of creatures entering the battlefield.
Machines
Artifacts
Artifact synergies, themed around Donatello and the Utrom aliens from Dimension X. Buzz Bots and Ravenous Robots do the heavy lifting.
Mutagen
Ramp / Card Draw
Draws cards and ramps, then converts Mutagen tokens into +1/+1 counters on something worth growing.
Disappear
Sacrifice / Control
A controlling sacrifice deck built on Disappear and Food, paying you off whenever a permanent you control leaves the battlefield.
Commander
A single precon launched alongside the set, rather than the four a tentpole expansion usually gets.
Leonardo, the Balance
“Turtle Power!” · Face commander
The deck's face commander, fronting a +1/+1 counters and Mutagen-token strategy.
Heroes in a Half Shell
“Turtle Power!” · Backup commander
The deck's second commander, and the reason Partner — Character select exists here: you can run it alongside Leonardo rather than choosing between them.
Building one of these into something of your own? The precon buying guide covers how to judge a deck, and the Commander deck template is the shape to build toward.

It released worldwide on March 6, 2026, under the set code TMT, as a Universes Beyond crossover.
Sneak lets you cast a spell by returning an unblocked creature to your hand during the declare blockers step, usually at a discount. The key difference is that Sneak is casting a spell, so it can be countered — ninjutsu is an activated ability, which can't. Ninjutsu also only appeared on creatures, while Sneak shows up on noncreature spells too.
An artifact token. Sacrifice it to put a +1/+1 counter on target creature, which means every card that makes one is simultaneously an artifact payoff and a +1/+1 counters payoff.
Five two-color pairs rather than the usual ten, because this is a smaller set: white-black Sneak, white-red Alliance, blue-red Machines (artifacts), blue-green Mutagen (ramp and card draw), and black-green Disappear (sacrifice and Food).
One, called Turtle Power!, rather than the four a tentpole set usually ships. It is led by Leonardo, the Balance, with Heroes in a Half Shell as a second commander via the Partner — Character select mechanic, and it plays +1/+1 counters and Mutagen tokens.
