Well, personally what Puppetmaster was first announce I was positive that the Cardian would finally be controllable. SE decided on the automaton(good pick).

Oh just thought of something...what if the "Cardian cards" could be used as a item to buff automaton temporarily. Sorta like a fusion moves, each of the (4) cards would buff particular stats of automaton one way. For example, RDM cards could buff enfeeblement strength, war cards melee damage, etc. Each value 1-10,J,Q,K and Ace could be a modifier to potency of buff?
