Only because they would have to be in the MU and Team 2 aren't leaving theirs so I reckon they would have the upper hand considering the two MXY's physics maybe wouldn't be as manipulative.
It's a guess though.
2 overpowered genies vs God split into two entities outside of their own multi-universe?
Because that's what Neutral Ground is.
Can Team 2 even leave MU? That's like leaving themselves!
I'm not educated in Cosmic MU enough to answer but I'll entertain by saying the two leprechauns win this for Team 2 on neutral ground is neutered ground......maybe!
Nah change my mind Team 2 kicks the little pricks asses through the cosmos by making them say their names backwards through TP.
