Yeah, if you try to use another move after that then it tells you you cannot do that or it fails, there are other ones like that Choice Band (doubles attack), and Choice Scarf (doubles speed). I can't wait, too!
Yeah, my sis likes it a little (plays every now and then)... Choice Specs requires you to use only one move (makes you switch out after that move), but it doulnes the power of specail attacks, so I pretty much 1HKO's the foe. Wide lens just increases the accuracy of all of the poke's moves.
