Borg are an artifact creature type introduced in Star Trek, appearing mostly in white, blue, and black. Nearly every Borg grants an ability to all artifact creatures you control, so the collective grows stronger with each drone added to the board. The assimilate mechanic steals an opponent's creature and adds it to your side with a +1/+1 counter, turning it into a Borg artifact creature that benefits from the same support.
The Borg Queen assimilates a creature from an opponent's library each time she enters or attacks, while Locutus of Borg and Type-03 Borg Vessel keep 1/1 Borg tokens flowing. One, Borg Evolved gives your entire artifact army flying, double strike, vigilance, menace, lifelink, and ward.
