As Adaptive Automaton enters the battlefield, choose a creature type. Adaptive Automaton is the chosen type in addition to its other types. Other creatures you control of the chosen type get +1/+1.
Hidden agenda Whenever a creature you control with the chosen name attacks, you may pay {W}. If you do, that creature gains indestructible until end of turn.
Flying {3}{W}, Sacrifice another artifact: Aerial Toastmaster assembles a Contraption. (Put the top card of your Contraption deck face up onto one of your sprockets.)
Choose an artist. Exile the top six cards of your library, then reveal cards from the top of your library until you reveal a card with art by the chosen artist. Put that card in your hand and exile all other cards revealed this way.
