What is preventing me from using the same Chandelure's ability twice in one turn if I have 2 Chandelure in play and retreat my active after using it's ability, send up my benched one then use it's ability, play Switch to put the one that used to be active back in the active spot and use it's ability again? I'm aware that it sais "once per turn", but I thought effects like that wore off after a Pokemon is benched? For example, if Beartic used Sheer Cold on an active Zekrom, it wouldn't be able to attack on the next turn unless the opponent had some way of getting it on the bench and back to the active spot, so what's preventing Chandelure from doing almost the same thing?
