Borg Queen, Perfection Manifest

Artifact creatures you control get +2/+0.
When Borg Queen enters, assimilate target creature card from an opponent's graveyard. (Put it onto the battlefield under your control with a +1/+1 counter. It's a Borg artifact creature and loses all other creature types.)

"I am the beginning, the end, the one who is many. I am the Borg."
