Gollum

Reveal Gollum only if there are 10 or more cards in
your graveyard.
Unnaturally Long Life: At the beginning of your upkeep, you may discard a card. If you do, gain life equal to the number of cards in all graveyards.
Raw and Wriggling: Destroy target tapped creature
and put a +1/+1 counter on target creature you control. Activate only any time you could cast a sorcery, and only once per a turn.
If you control The One Ring and Sauron and Frodo and Samwise have been defeated, you win the game.
