Diabolic Ritual

Put the top card of your library into your
graveyard. If that card is a nonland card, you may
cast it this turn. You may use mana as if it were
mana of any color to cast that card. If that card is
a land card, repeat this process until you reveal a
non-land card. Diabolic Ritual deals 1 damage to
target player for each land card put into your graveyard this way.
