Untap all creatures and lands you control during each other player's untap step. You may cast creature spells as though they had flash.

: Add . : Each player gains control of all creatures they own.

Whenever an opponent casts a spell, you may exchange control of this creature and that spell. If you do, you may choose new targets for the spell. (If the spell becomes a permanent, you control that permanent.)

Each player can't cast more than one spell each turn.
