Gloria Corrupted

Menace
Whenever Gloria Corrupted enters the battlefield
or attacks, invoke X, where X is the amount of
life you've lost this turn. (Create a Vessel token,
then put X +1/+1 counters on it. It's a black artifact
token with "{b}, Exile a creature card from your hand: Transform this artifact". It transforms into a copy of
the exiled card, except it's a 0/0 black Horror.)
