Eclipse Titan

Lifelink
When Eclipse Titan enters the battlefield, exile
all nonland permanents with mana value 5 or less
until Eclipse Titan leaves the battlefield.
Whenever Eclipse Titan attacks a player, you
may pay {w}{b} and put a nonland card exiled by it
into its owner's graveyard. If you do, the
defending player loses X life, where X is that
card's mana value.
