The Nightmoon Cannibal

Whenever a creature dies, reveal cards from the
top of your library until you reveal a basic land
that adds mana of the same color of the creature
that died. Put it onto the battlefield tapped and
the rest into your graveyard. If a land wasn't put
onto the battlefield this way, you lose the game.
{0}: This creature loses all abilities until your
next upkeep. You lose 2 life.
