Heirloom-Bound Fiend

Flying, Trample
When Heirloom-Bound Fiend enters the battlefield, put a vessel counter on target artifact.
When there are no permanents with vessel
counters on them, sacrifice Heirloom-Bound
Fiend.

The demons of amonkhet were wanderers, doomed to
travel the wastes, willing to strike any kind of bargain
to gain the strength required to survive
