The Lich

When you have no opponents, you win the game.
Turn The Lich face up, exile target creature or
planeswalker card from your graveyard. Put a
copy of it onto the battlefield under your control
and put a hexproof counter on it. It has:
"If a source would deal damage to you or to a
planeswalker you control, prevent all but 1 of that
damage."
I need to end this before I loose myself.
