Assimilate the Wounded (Surge Foil)

For each opponent, assimilate up to one target creature card from that player's graveyard that was put there from the battlefield this turn. (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.)

Nanoprobes subvert the will to the Collective even before the first implant is added.
