i think the warp selects were the trigger commands you use to move your characters from one space to another when fighting the spectral keeper right before you fight yunalesca. Hint LOTS OF HOLY WATER, EYE DROPS, AND ECHO SCREENS FOR THE FIGHT AGAINST YUNALESCA!!!!!!!!!!!!!!!
best is to just keep auron, lulu, and yuna in play, have auron just attack, lulu doublecast blizzaga, and yuna heal and cure. Yunalesca has a bad habit of using blindness on attackers, and silence on spellcasters that damage her. also, watch out for zombie until her last form where she will cast megadeath, killing all your non-zombied characters (ooh, yeah, megadeath, good band).
hope this helps,
