Detailing situation:
opponent had A umpmaster with Gonk on it and one damage card. The end of the game was rapidly approaching. Tactically, one option he could play for was to retain full points on the Jump. Jump also was equipped with Experimental Interface.
Opponent moved the Jumpmasters. Surveys the battlefield. Announces "focus." Places focus token. Announces Gonk's ability to put a token on Gonk. Then realizes that he cannot also add that token to the Jumpmasters. Declares that he wants to rescind the focus token. I'm actually inclined to allow him to, but opponent insists that he has the right to do so because he didn't measure anything.
Is this correct? I understand "focus...err, I mean evade" as a fix, but are you allowed to rescind two actions back when you realize you goofed up? Just want to understand how "casual" the rules are baked to be. As said, I was inclined to allow it, but this doesn't sound like a right that a rules system would grant a player.
