The Demonkey

At the beginning of your upkeep, put a spell counter on The Demonkey.
Remove a spell counter from The Demonkey: Search your library for a Pact spell, reveal it, and put it in your hand. You lose life equal to its Pact cost. Then shuffle your library.
Remove two spell counters from The Demonkey: You may play a Pact spell form your hand without paying its mana cost.
