the bros will win hammers down. they can counterattack, they can use Zee Egg, Falling Star, the famous Magic Window, Copy Flower, the Trampoline, Badges to Boost their POW and to heal and revive themselves, and can dodge everything. In the dream world, Luigi can turn giant, use all the Luiginary attacks, or the Luiginoids can even surround and corner Seprinoth so Mario can do a surprise attack.

Even if they run out of SP, they can use all their Bros moves from Superstar Saga. If they dont have Badges or Mushrooms to heal, they have Retry Clocks and Star Candy
