Remix and put 3 of your characters in to battle Utsuho, Mechatera, and Flowey. Utsuho: Main Attacker. She'll be doing ALL the high damage. Mechatera: Defender. It'll put up defenses and stall for time. Flowey: Trickster. Will cancel out your attacks and inflict debuffs. Oh, and DON'T CHANGE OR ADD MUSIC! One battle at a time, please! I wanna be able to work on other things while this is up. >_>
Mechatera activates its ability after lasting a few turns with a status problem, gaining 2 stages of Defense Increase. Meanwhile, Flowey gives your team "Frightening Look" Which confused Link and Circlepunch. Dunk had WAAAAY too many courage points to be affected, though.
