When this card enters the battlefield, put 3
counters on it. At the beginning of your upkeep,
if there are no counters on this card, destroy it.
Remove a counter from this card: exile an artifact creature from your library. You must control an artifact Dragon to use this ability, and it can only
be used once per turn as a sorcery. When this
card leaves the battlefield, return all your exiled artifact creatures to the battlefield, then destroy
all enchantments you control.
