Lord of the Forge

Blaze 3, Haste, Lavatouch 3 (Whenever this
creature deals damage to a creature, put a -3/-3
counter on that creature. Then add {r}. This
mana doesn't empty from your mana pool as
steps and phases end.)
At the beginning of each player's end step, if no creatures attacked this turn, put a fury counter on
Lord of the Forge. Then Lord of the Forge deals damage equal to the number of fury counters on
it to that player.
