@Serracollector A lot of the times, Animation Module is getting you a lot more than one token per creature.
Consider, most dramatically, the case of Arcbound Ravager. Arcbound Ravager + Genesis Chamber = a 2/2 Arcbound Ravager. Arcbound Ravager + Animation Module = a Ravager that grows every turn for each spare mana you have, usually ending around 5/5 before the game ends, sometimes hitting 10/10 or so on a stalled board.
Ctrl+F for Notable Interactions to see a list of all the neat stuff Module does, basically all of which is better than a single 1/1.
I'm pretty sure an Animation Module in play is better than a Genesis Chamber, even if it cost 2 mana ... but if I had to pay 2 for it I don't think I would run the card - the deck is pretty loaded up with 2-drops as it is.
If I'm being honest I haven't tested Chamber in this list - but I have no interest, I've played a lot with the card in other decks and I just don't think it does enough to be worth the slot.
For what it's worth, the last time I won with Genesis Chamber in vintage, it was with this deck ... my opponent played a Genesis Chamber and I made more tokens off it than he did.
