I've not thought about it specifically with this deck. There has been a small amount of talk in the BTCG discord about a Balatro-like game mode vs. an automaton. Makes me think of the old fan-made MtG Horde format, which WotC had an "official" take on for the Theros block. I also know the game Keyforge has "adventure" decks which allow co-op play for up to three players. I think that designing cards for automata has pretty different considerations than for people; card behavior either has to be completely deterministic or randomized in a way that minimally disrupts game flow (like revealing cards off the top of the deck). Effects like "deal 1 damage to any card" need to be rewritten so there's no debate about how to decide targets for the automaton. "Deal 1 damage to a random card an opponent controls" (picking a card from an arbitrarily-sized pool at random is best for nonrepeatable effects) or "deal 1 damage to the highest-level Character card an opponent controls" (how do you decide ties?)
The other route to go by, which would require far fewer format-specific design considerations, is to make it a human-piloted Archenemy deck that's meant to be ganged up on. BTGC power level is still up in the air though, so... (shrugs)
