Chasm Prowler

Molten 2 (This creature enters the battlefield with 2
magma counters on it. It has haste as long as it has a
magma counter. At the beginning of your upkeep,
remove a magma counter from it. When the last is removed, it loses all abilities, then gains defender.)
At the beginning of your end step, if Chasm
Prowler didn't attack this turn, put a magma
counter on it.
