Keiran

Imprint - When Keiran enters the battlefield,
you may exile target nontoken creature.
As long as a card exiled with Keiran is a creature
card, Keiran has the power, toughness, and
creature types of the last creature card exiled
with Keiran. It's still a Shapeshifter.
"It's an impressive looking blade, but nothing more."
- Keiran
