Glissa, Herald of Predation

At the beginning of combat on your turn, choose
one —
• Incubate 2 twice. (To incubate 2, create an
Incubator token with two +1/+1 counters on it and
"{2}: Transform this artifact." It transforms into a
0/0 Phyrexian artifact creature.)
• Transform all Incubator tokens you control.
• Phyrexians you control gain first strike and
deathtouch until end of turn.
