Shaun, Father of Synths

CMC 5

Legendary Creature — Human Scientist

Whenever you attack, you may create a tapped and attacking token that's a copy of target attacking legendary creature you control other than Shaun, except it's not legendary and it's a Synth artifact creature in addition to its other types. When Shaun leaves the battlefield, exile all Synth tokens you control.
