Balrog, Demon of Power

Trample.
Tempest of Fire - Whenever the Balrog, Demon
of Power deals combat damage to an opponent,
put a blaze counter on up to one of his or her
lands. For as long as that land has a blaze
counter on it, it has "At the beginning of your
upkeep, this land deals 1 damage to you." (The
land continues to burn after Obsidian Fireheart has
left the battlefield)
