Too Many Ninjas!

Return each creature card you control to its
owner's hand. Create a token copy of each of those creatures except the tokens are named
Ninja and are not legendary. If any tokens
were destroyed in this process, create token
copies of them too. If any of these copies had
power and toughness less than 2 they have power
and toughness of 2.

You get an emblem with "Creatures you control lose defender."
