Input_Command 
7 Mana: Your opponent can not play minions.
If they had taunt, it wouldn't be overpowered. If you removed "That can not attack" it would be a step in the right direction. Zero attack minions already can't attack, but it would open for counterplay by allowing your opponent to remove them by buffing them.
