Team FirelordvsTeam Crystal

Neutral the only one of team 1 who I am aware of having time stop resistance is Natsu...
Esdeath can even freeze time.

Team Crystal Laufey is an elemental like Surtur which means he is Skyfather level.
He solos.

Team Firelord Pretty much narrows down to Firestorm and Etrigan vs Iceman, and either of them have a good chance of soloing.
