Kampit the Unexpected

Kampit enters the battlefield with X +1/+1
counters. When Kampit enters the battlefield,
for each +1/+1 counter on him, exile cards
from the top of your library until you exile
instant or sorcery card, you may cast it without
paying its mana cost. Put the exiled cards on
the bottom of your library in a random order.
Theres a time and place for everything, and I believe
its called 'fan fiction'.
