Cthulu, Desolation Incarnate

At the beginning of your upkeep, each
player puts the top two cards of their library
into their graveyard. For each land card put
into a graveyard this way this turn, each
player loses 1 life and you draw a card.
Whenever a card is put into a graveyard
from anywhere, Cthulu gets +1/+0 until
end of turn.
