TMNT’s Sneak Mechanic: Clever Homage, or Dumbed Down Knock-Off?

Teenage Mutant Ninja Turtle’s official release is upon us, and it brings a new ninja-themed mechanic: sneak! Though sneak bears a passing resemblance to the ninjutsu mechanic introduced in Betrayers of Kamigawa, different timing restrictions and mechanic types separate the two, and it’s important to understand the differences and advantages.

The Basics

Ninjutsu is an activated ability that allows you to pay mana and return an unblocked creature you control to your hand to put the creature with ninjutsu onto the battlefield tapped and attacking.

Sneak is an alternative cost that lets you return an unblocked attacking creature to your hand to cast a card for its sneak cost during the declare blockers step. Sneak causes creatures enter tapped and attacking.

Ninjutsu is an activated ability used from the hand, while sneak is an alternative cost. Because a card with ninjutsu doesn’t go on the stack, just the ninjutsu ability, it can’t get countered by most countermagic. But since sneak is an alternative cost, the card goes onto the stack, and can be countered.

Sneak also has a timing restriction. You can only cast a sneak card for its alternative cost in the declare blockers step, so after blockers have been declared, but before the end of combat steps. Casting a spell for its sneak cost ignores timing restrictions for creatures and sorceries.

The last big difference is that any spell could have sneak while only permanents get ninjutsu. Since ninjutsu puts the card directly into play, it doesn’t work with non-permanent cards. But since you cast a sneak spell, instants and sorceries are fair game.

Those are the bare-bones differences. A creature that gets ninjutsu’d into play does not go on the stack, while a card cast with sneak does; cards can only be cast for their sneak cost in the declare blockers step; and more card types can use sneak than can use ninjutsu. Despite these differences, they share common ground as both require evasive creatures to enable them.

Advantages of Ninjutsu

The biggest advantage to ninjutsu over sneak is the whole circumventing the stack aspect. Some cards counter activated abilities, but they’re so infrequently played that you rarely need to worry about Fallen Shinobi running into countermagic. Regular removal like Infernal Grasp still works, but the window for interaction closes dramatically.

Ninjutsu enables weird lines because you can use ninjutsu any time after the declare blockers step, when creatures received the “blocked” or “unblocked” status.

For a practical example of this use, consider Kappa Tech-Wrecker and Moon-Circuit Hacker from Kamigawa: Neon Dynasty. Let’s say you ninjutsu KTW into play before combat damage, then use its ability. After combat damage has been dealt, in the end of combat step, KTW still counts as an unblocked creature, so you can ninjutsu MCH into play by returning the Tech-Wrecker to your hand.

The Hacker won’t deal damage for its saboteur ability, but you get to reuse KTW next combat. This trick can also protect fragile ninjas like Mist-Syndicate Naga or recycle the enters abilities on cards like Moonsnare Specialist and Sakashima's Student.

Since ninjutsu is an activated ability, it dodges tax cards and stax effects. Sphere of Resistance doesn’t make it cost more, and Rule of Law can’t stop you from using multiple ninjutsu abilities.

Advantages of Sneak

Ninjutsu does plenty of cool stuff, but sneak has its own advantages. To start, it’s more intuitive than ninjutsu. The old mechanic is cool and powerful, but, for newer players especially, it makes sense that paying mana to put a creature into play uses the stack. It also allows for the design of ninja commanders that use the ninja mechanics; ninjutsu puts permanents into play from your hand, so it doesn’t interact with the command zone. There’s Yuriko, the Tiger's Shadow but we don’t need more commander ninjutsu.

It’s also really cool that sneak can be used on instants and sorceries, and it leads to extremely interesting designs. Is a Demonic Tutor worth the tempo lose of bouncing a creature? How many cheap creatures can the mill deck run for Kitsune's Technique?

A gameplay boon to sneak is the reverse of ninjustu’s tax evasion: you can reduce a sneak cost or even cheat it much easier than ninjutsu.

Though sneak can’t perform the tricks ninjutsu can, it opens up a ton of design space in the future. If sneak comes back and isn’t regulated to this set alone, it could be wonderful.
