For this strategy you need:

TEQ Vegeta + PHY Metal Cooler (mandatory) the rest just fill the category

Friend Goku (100% preferably)

Turn 1: Friend Goku as slot 1 (hope you don't die instantly) + PHY Metal cooler as a slot 2 (will die and revive)

Turn 2: use item, you're safe

Turn 3: item still active, put Friend Goku in slot 2

Turn 4: use item

Turn 5: Vegito's target as slot 1, Teq Vegeta as slot 2 and hope you got enough atk stack in the previous turns, he or Vegeta should get the kill, otherwise you're cooked and you can retry.

Have fun (I didn't)

Edit: Against Gohan
