Depends on what you want but from what I can see you should either go with a slasher team or a PSY team.

Slasher:
Enraged arlong - capt
asura zoro
kuro or buggy (whichever you prefer but kuro has a higher damage cap)
Shanks (You should try to evolve him asap as he is good for both teams)
Golden pound usopp - cuz duh

PSY team:
Shanks (evolved as capt)
Marco - (until you evolve shanks use as captain, can also use him as a captain later if you are confident at maintaining full hp)
Golden pound usopp
Mr 2 - needs to be evolved as his special is pretty solid for psy teams
Heavy point chopper

For now I would suggest just using the slasher lineup as you need to evolve a lot of your psy characters before they are even close to same amt of damage your slasher lineup can do now. Double psy captains can be really solid but you need the pieces for that to work, also a good deal of the heavy hitters for psy are still not available (garp, urogue and master sergeant coby).

okay thanks that info really helps
