Demon Prince

When the Demon Prince enters the battlefield,
search your graveyard for Demon in pain and/or
Demon from below. If you find them, exile
them and give the Demon Prince respectively:
- +4/+1 for the Demon in pain.
- +1/+4 for the Demon from below.
- +7/+7 for both (excludes the two firsts).
Thought to be slain by Lorian, the Demon Prince is
effectively the last of his kind.
