A quick guide I made while taking notes, these could probably be optimized and changed however this is more of tips to do the run. (everything is on easy difficulty unless noted differently)

1: Go to the top and repeatedly dair 2: Wait it out 3: Normal(Faster) - Run up grab, forward throw into fair and end it with up-b Easy(Slower) - Up-b 4: Break the platforms going clockwise and usind d-smash 5: Switch to charizard and use side-b, f-smash, u-smash, and up-b 6: Run asfast as possible at the end, wait it out 7: Move to the right of the stage where the grass and road connect and f-smash 8: Down-b in the middle 10: Go Pikachu and go to the middle, spam down-b 11: U-air them 12: Put both in eggs at the same time jump to the platforms right side in the beginning 13: Wait it out, try to get two in one shot 14: Wait of screen and grab the oppnent 15: Get him off stage 16: Don't hit the smash ball if you can't break it and you're going to push it away from you
17: Go hard difficulty and wait 18: Stay offscreen, throw and attack 19: Use shells 20: Go Pikachu and use down-b in the middle 21: Use up-smash and f-smash 22: Have Dk kill the opponents 23: Stay alive, run around, get into the capsule and attack your opponent before or while in the capsule 24: Check containers and get the smash ball, try to get a two in one 25: Grab forward throw 26: Use f-smash and grabs. Use bomb items, assist trophies, and pokéballs 27: Go to the bottom left corner under the large solid platform, roll into the ledge and face to the right, use up-throw when they get close 28: Mkae sure they are all red and not orange, go clockwise and use d-smash 29: Go pikachu and go to the left and back throw 30: Go to the left and spam up-smash, containers might spawn and roll back and forth, this will help kill sonics 31: Charge up-smash, use f-smash, try spiking, use walk-off to your advantage, and do marth stuff 32: Use dair to spike and use your aerials 33: Go left and use grabs, warlock punches, smash attacks, and dair/down-b spikes 34: Go Pikachu and spam down-smash in the middle(waht a surprise) 35: Tricky, try killing as fast as possible 36: Also tricky, use up-smash 37: Build up damage early, try not to kill them until you're in the air, then use up-smash and up-b 38: Up-smash and items
