Bow to My Command

(An ongoing scheme remains face up until it's abandoned.) Spells you cast cost 1 less to cast. At the beginning of your opponents' end step, if they cast four or more spells this turn, abandon this scheme.

When you set this scheme in motion, add UBR. When you set this scheme in motion, if you control six or more lands, you may search your library for a card with mana value 6 or greater, reveal it, put it into your hand, then shuffle.

When you set this scheme in motion, look at the top four cards of your library and separate them into a face-down pile and a face-up pile. An opponent chooses one of those piles. Put the cards in that pile into your hand and the rest on the bottom of your library in any order.

When you set this scheme in motion, create a 3/3 black Horror creature token and prevent all damage that would be dealt to creatures you control this turn.

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

When you set this scheme in motion, for each opponent, create a 3/3 black Horror creature token that attacks that player each combat if able.

When you set this scheme in motion, until your next turn, up to one target opponent can't attack with creatures, up to one target opponent can't cast creature spells, and up to one target opponent can't cast noncreature spells. You can't choose any player as a target more than once.

When you set this scheme in motion, destroy target creature an opponent controls. If a creature is destroyed this way, you gain life equal to its toughness.
