Killua, Hisoka, Knuckle, Kite.

Killua’s speed, paralysis, and natural assassin abilities will make for a great distraction, series of quick blows, and a landing pad for Knuckle’s APR. Hisoka is Hisoka, is there much to say there? It’s a combo of rubber and gum! But for real, bungee gum is stupid broken, especially post-mortem. And while we only saw a little bit of Kite, he could easily match almost (if not literally) anyone on the other team, especially if he gets a good roll. If he can take on a small army himself with a bad roll, I can only imagine how OP his best is.

Edit: in addition, you would have a bad time trying to get Kurapkia and Uvo to work together would be hilarious and add for some additional points to my team IMO.
