Wow, you're talking about Cerberus, the one who can cast Triple without trouble, and the only way I know is use Dispel, but for the meanings of the challenge, umm, kinda difficult, if you can use limits, then use Selphie's (only if you can) or the ever confiable Renzokuken and you could also use the Draw command (thing I don't recommend, if you want this to be a real challenge )
