Adam, Codebase Guardian

Whenever Adam attacks, create a colorless Refactor artifact token with "{t}, Sacrifice this token: Return target artifact to its owner's hand. Then you may cast an artifact spell with equal or lesser mana value from your hand without paying its mana cost."

Exhaust —{r}{r/w}{w}: Adam gains double strike and indestructible until your next turn.

"Time to go all out, huh? Yeah... I think so, too."
