Orianna, Robot Commander

Construct 2 ( When a unit dies under your control,
you may exile the destroyed unit. If you do, create two
construct tokens with power and toughness equal to the destroyed units power. )
If a robotic unit enters the battlefield under your control, you may create a 1/1 flying drone
creature token. It gains haste until end of turn.
Damage dealt to 400 unit robots is prevented
while Orianna is on the battlefield.
