(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)

[I] Assimilate target nonartifact creature an opponent controls. (Gain control of it and put a +1/+1 counter on it. It's a Borg artifact creature and loses all other creature types.)

[II] Artifact creatures you control get +2/+2 until end of turn.

[III] Exile the Borg assimilated with this Saga, then return it to the battlefield under its owner's control.
