Soul of Cinder

When Soul of Cinder enters the battlefield,
you may exile any number of creature cards from
your graveyard. Soul of Cinder enters the battlefield with X +1/+1 counters on it, where X
is the total power of the exiled cards.
Whenever Soul of Cinder deals combat damage to
a player, create a colorless Artifact Equipment
token named "Ashen Estus Flask" with "equipped creature gets +2/+2 and has lifelink."
Attach it to a creature you control.
