Mass of Mysteries

Legendary Creature — Elemental

Mass of Mysteries wants a deck that is built around one creature type, like Elves or Dragons. It also works in a deck built around Elementals.

First strike, vigilance, trample

At the beginning of combat on your turn, another target Elemental you control gains myriad until end of turn. (Whenever it attacks, for each opponent other than defending player, you may create a token copy that's tapped and attacking that player or a planeswalker they control. Exile the tokens at end of combat.)

Wizards of the Coast 17 Nov 2025

Although the tokens enter attacking, they were never declared as attackers. Abilities that trigger whenever a creature attacks won't trigger, including the myriad ability of the tokens. If there are any costs to have a creature attack, those costs won't apply to the tokens.

Wizards of the Coast 17 Nov 2025

Any "enters" abilities of the copied creature will trigger when the tokens enter. Any "as [this creature] enters" or "[this creature] enters with" abilities of the copied creature will also work.

Wizards of the Coast 17 Nov 2025

Each token copies exactly what was printed on the original creature and nothing else. It doesn't copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

Wizards of the Coast 17 Nov 2025

If an instance of myriad creates more than one token for any given player (due to an effect such as the one Doubling Season creates), you may choose separately for each token whether it's attacking the player or a planeswalker they control.

Wizards of the Coast 17 Nov 2025

If the defending player is your only opponent, no tokens are put onto the battlefield.

Wizards of the Coast 17 Nov 2025

The term "defending player" in the myriad rules (or any other ability of an attacking creature) refers to the player the creature with myriad was attacking, the controller of the planeswalker it was attacking, or the protector of the battle it was attacking at the time the ability resolves. If that creature is no longer attacking, it refers to the appropriate player based on who or what the creature was last attacking.

Wizards of the Coast 17 Nov 2025

The tokens created by a single instance of myriad all enter at the same time.

Wizards of the Coast 17 Nov 2025

You choose whether each token is attacking the player or a planeswalker they control as the token is created. If it's attacking a planeswalker, you choose which one. You can't have any of the tokens attack a battle.

Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it.
