It's kinda funny if sora can summon the attraction flow anytime he want, imagine in the final battle we fight xehanort and then suddenly tea cups comes out from nowhere and hit xehanort so many time
It will depend on what situation you're in, so depending on what enemies you're facing and what world you're in, what attraction will show up is unknown until you've actually activated it. Once you do activate it it's a very flashy move and you can attack your enemies in that way."
