Arkabek, Shambling Amalgam

Whenever Arkabek attacks or blocks, sacrifice it
unless there is an Equipment attached to it.
Whenever you cast an Equipment spell, you
may return Arkabek from your graveyard to the battlefield tapped. If you do, that Equipment
enters the battlefield attached to it.
"I've seen it dead before, certainly! But not even its
rotting corpse can resist the glimmer of a new trinket."
