There exist an in-game item/concept called Cardians. When the puppet master job was first introduced, I thought the job would be controlling Cardian rather the Automaton. I'd like SquareEnix to introduce a new job ability for puppet master that use the auction house "Cardian cards" as a form of quick summons. Think a Summoners elemental spirits mixed with automaton.
The card use could have a timer of 5 minutes that "summons" a Cardian. The Cardian could stick around for 1 min or two and depending on the card type fight, buff or nuke. Could be useful while automaton timer is down.
