Dance, Pathetic Marionette

When you set this scheme in motion, each opponent reveals cards from the top of their library until they reveal a creature card. Choose one of the revealed creature cards and put it onto the battlefield under your control. Put all other cards revealed this way into their owners' graveyards.

I Call for Slaughter

When you set this scheme in motion, create three 1/1 red Devil creature tokens with "When this token dies, it deals 1 damage to any target." They gain haste until end of turn. If a source you control would deal damage this turn, it deals that much damage plus 1 instead.

All in Good Time

When you set this scheme in motion, take an extra turn after this one. Schemes can't be set in motion that turn.

I Know All, I See All

(An ongoing scheme remains face up until it's abandoned.)
Untap all permanents you control during each opponent's untap step.
At the beginning of each end step, if three or more cards were put into your graveyard this turn from anywhere, abandon this scheme.

Ignite the Cloneforge!

When you set this scheme in motion, create a token that's a copy of target permanent an opponent controls.

I Bask in Your Silent Awe

(An ongoing scheme remains face up until it's abandoned.)
Each opponent can't cast more than one spell each turn.
At the beginning of your upkeep, if no opponent cast a spell since your last turn ended, abandon this scheme.

Every Hope Shall Vanish

When you set this scheme in motion, each opponent reveals their hand. Choose a nonland card from each of those hands. Those players discard those cards.

Every Dream a Nightmare

When you set this scheme in motion, each opponent discards a card. You draw a card for each land card discarded this way.
