There could be two opposing cards... or maybe one double sided card?
First SA: "Remove all counters on cards in set aside."
Second SA: "Double all counters on cards in set aside. If the resulting amount of counters is more than the card required, return the cards as described on their owners next upkeep phase."
Second one doesn't make a huge difference on 1-2 turn cards, but on the 7 card one or 1/1 per turn cards, it could be a huge help.
