Vigilance

When Shaun & Rebecca enters, search your graveyard, hand, and library for a card named The Animus and put it onto the battlefield, then shuffle.

: Add . When you do, mill two cards.

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.
