Whenever chaos ensues, draw a card for each land you control.

Creatures without flying or islandwalk can't attack.

(An ongoing scheme remains face up until it's abandoned.)

When you set this scheme in motion, choose an opponent.

Permanents the chosen player controls don't untap during their untap step.
