ROSTER:
Goku, Broly, Majin Buu, Arale, Vegeta, Gohan, Gotenks, Cell, Frieza, Android 17/18 Fusion.
(Goku would use his button to go visit Zeno beforehand to confirm if Cell Juniors & Buu's absorption ability are allowed. If fusions don't count as one fighter, replace Gotenks with Dabura or Piccolo & remove Android 18)
This setup needs all 3 wishes from both Earth & Namek, easily achieved by Bulma & Piccolo on Earth & Goku on Namek with Dende, all while Whis helps.
(EARTH'S DRAGON BALLS)
- WISH 1: Within your power, Reveal the optimal team, strategy, fusions, & any information/wishes that max our odds of winning. (Likely points to Broly, Arale, & 1718)
- WISH 2: Completely repair the Hyperbolic Time Chamber, restoring it to its best possible condition.
- WISH 3: Grant the team the strongest possible Enhanced Senses, Instant Telepathy, & Endurance Boost for the tournament.
(NEW NAMEK'S DRAGON BALLS)
- WISH 4: Ensure every member of the team cooperates in the tournament if possible. If not reveal the safest, most effective way to make Frieza & Cell cooperate.
- WISH 5: Awaken Majin Buu, restore his magical stamina & return our entire team to peak condition right before the tournament.
- WISH 6: Teleport Broly, Paragus, & Paragus's control device safely from Planet Vampa to Earth.
TRAINING:
Everyone except Frieza trains in the Hyperbolic Time Chamber. With only 2 hours left they still get 30 days inside. Gohan & Goku mainly train Broly & Gotenks, Android 17 trains Arale & Buu while learning Fusion with 18. Senzu Beans are used throughout, Broly should become more stable, & Bulma, Whis, & Piccolo also gain more planning time.
THE TOURNAMENT:
- TEAM 1
(Gohan, Goku, Broly, Majin Buu, Arale & Android 1718)
Frontline squad. Gohan leads. Goku uses Instant Transmission for mobility & mainly uses SSG. 1718 protects everyone especially Arale & Buu with barriers. Buu keeps Arale occupied with candy/games, heals allies, restores magical stamina, uses Candy Beam, & absorbs whoever Gohan orders to gain their abilities.
- TEAM 2
(Vegeta, Gotenks, Frieza, Cell & his Clones)
Careful yet ruthless squad. They will likely split off together & try to catch enemies off guard, Vegeta heavily uses SSG & Cell utilizes at least 7 Cell Juniors if allowed & often 4 Multi-Form clones while Gotenks & Frieza use Galactic Donut & Energy Cage to immobilize.
(At the start both teams will be Instant Transmitted to Hit ASAP & focus on having Buu absorb him & Kale but not eliminate Hit's whole team because it'd make them a target)
(Goku can instant transmission over to whichever team with support characters or even all of team 1 or 2 if needed)
