i don’t think that’s the case at all. Geist got a few trashcan cards in his cycle, but there were plenty of them before. it’s just that it was something that criminal did (grappling hook, cortez chip, crash space, decoy, crescentus, etc.) but never was a fully fledged-out archetype. and as tvaduva said, not really anything criminal did necessarily more than others.
drawing cards is very shaper, so that’s probably what he meant by that comment.
but Geist is a minifaction in the same sense Noise was. you can’t build just any anarch or criminal deck and slot one of those IDs into it, nor can you take any old deck for another ID and just swap to Noise/Geist. they play very differently and definitely require lots of the cards that trigger their ID ability, much moreso than you would probably normally put in your deck without it
honestly, the only reason Noise wasn’t called a minifaction that often is because he was around for such a long time before the minifactions existed. Geist was only around for a few months before them
