Ligma, Balls

Whenever Ligma, Balls enters the battlefield
or attacks, put a Gotem counter on target
opponent
Whenever Ligma, Balls deals combat damage
to a player, exile the top X cards of that
player's library, where X is equal to the
amount of Gotem counters on that player.
You may cast nonland cards exiled this way,
and you may spend mana as though it were
any color to cast them.
