The ability to not claim extra moves sent by a team mate.
It happened to me yesterday. I finally got some extra moves from my teammate but it was afer a game that i just couldnt catch a decent break on so at the end i still had something like 50 jellies to collect. No way to do that in just two moves. But i claimed the two moves and played them and of course failed at the level. But the very next game i only had two jellies to clear at the end and wishd that i was able to have nit claimed he extra moves from the game before and they were available to me to use.
