There is a f2p team that has:
MC / MC
Arlong / Mihawk (Max skilled)
Perona / GP Ussop
Most teams have Jozu though.
Gamewith had one with 2x Mihawk, Mr1, Ohm, Jozu and GP Ussop. Dunno if you can change Jozu for Perona here.
Ohm is one of Enel priests.
I'm planning to use 2x Mihawk since MC is iffy. There is less room for error than with Dual Mihawk. Also, G3 team with Arlong, GP Usopp, Jozu, Mihawk is another good option.
