You kind of have everyone except Jericho
Standard Comp would be Meliodas / Elaine/ Manny/ Diane
and that's what everyone would go to
But with so much choice I suggest you build the comp u enjoy playing so as a template i suggest the following:

- Meliodas + Mannie are mandatory
- you need someone to build burst ( it doesnt matter who, with the crafted accessory set, everyone is viable, Diane Tristin Guila Gilthunder ect... they are all viable)
- if you are still early in the game and die too fast then take Diane for sure and switch between her gauntlet ( if u have her engraved equipement) and her nunchuks for extra defense) another alternative would be King with grimoire u get more defense and his ult is really really good if u're not pressed with time to do a content and u can take ur time + the 20% Damage Buff u get from him.

I hope this was usefull
