Ditto

When Ditto enters the battlefield, you may exile
target nontoken creature. As long as the exiled
card is a creature card, Ditto has that card's
power, toughness, and creature types. It's still a Pokemon and Shapeshifter.
"What? Did you think Ditto transforms simply by imitating what it sees? Don't be a fool--if that were the
case, how could Ditto duplicate essential organs?"
