Checks and Balances

Enchantment, 2U (3)
Whenever any spell is played, counter that spell if each player, other than the caster and his or her teammates, agrees to choose and discard a card. Those players must discard those cards after agreeing.
Checks and Balances may be played only in a game with three or more players.
