Pristine Heirloom

Equipped creature gets +5/+0 and has vigilance.
Whenever equipped creature deals damage, put a
scuff counter on Pristine Heirloom.
As long as there are five or more scuff counters
on Pristine Heirloom, it loses all abilities and is
not an equipment. (It becomes unattached from any creatures it's equipped to.)
