My wife was SO down on herself for not catching that right away.
The MESSED UP thing about deceptive players is when you catch them, the action is hard to rewind and YOU end up with some kind of a penalty for telling the judge! (i.e. "you get a caution and you get a warning" or.. "you get a warning and you get a prize card").
Rogue, please keep in mind that all of these penalties are simply for tracking, and are not intended to be any kind of punishment for telling a judge about the problem. You want another example of deceptive play? How's this?
Player A, using Torterrible, has two Turtwigs and a Treecko benched. He accidentally plays a Grovyle onto a Turtwig, obviously meaning to evolve Treecko into Grovyle, but simply places the card onto Turtwig instead.
Player B sees the mistake, but pretends not to, and waits for the situation to become unwindable.
Several turns later, near the end of the game, Player B "notices" the Sceptile that Player A has is evolved from a Turtwig and calls for a judge, causing Player A to receive a GL.
Now, if Player B doesn't get a penalty, he can just do this again later, either much farther into that tournament, or at a different tournament. If he gets a Warning, it would be reported to POP, and if he did this, say, once every tournament, there would be a noticable pattern, which POP would be alerted to.
If Player B honestly hadn't noticed the mistake, it would almost certainly not happen enough to cause any kind of problem for them.
So, yeah, sorry to rant, but had to clear up any possible misunderstandings.
