Gollum, Ring Bearer

Corruption 2
Gollum has shadow as long as it has a corruption counter on it.
At the beginning of your upkeep, target opponent chooses a card type. Reveal the top card of your library. If that card isn't the chosen card type, put a corruption counter on Gollum.
At the beginning of your end step, if Gollum has a corruption counter on it, draw a card and your opponent discards a card.
