SCP 963 Immortality Amulet

Indestructible, Hexproof
When SCP 963 enters the battlefield, exile a
creature you control.
Equipped creature has all abilities of the exiled
creature.
At the beginning of your upkeep, put an anomaly
counter on equipped creature. Then, if there are
5 or more anomaly counters on it, sacrifice it.
Make a token copy of exiled creature except it
isn't legendary. Attach SCP 963 to it.
