Need some advice in team building against smoker, still new :)

Hello everyone

Im still kind of new and I cant get past Smoker. I have problems with putting up a good team with what I have and which I should focus to evolve and level up. Im focusing on the story since I dont have much to come with to event island

These are what I have:
Luffy gum gum bazooka lvl 25
Sanji Plastic Surgery Shot lvl 18
Nami lvl 20
Roronoa Zoro Three thousand worlds lvl max (trying to get him to evolve into ashura)
Usopp Golden Pound lvl 19
Trafalgar Law Room lvl 31
Kuro of a hundred plans lvl 24
Killer lvl 20
Marco the Phoenix lvl 19
Miss Wednesday lvl 20
Buggy lvl 12
Portgas D. Ace (Mt. Corvo's Brother's 3, dont now what he's good for)

Is there anyone I should try and farm to make a team good? I do like slasher teams but I dont mind which ever  Thanks in advance!

Try farming for arlong, if you want a slasher team.
Also for Smoker you need a good force team (red team).

On extra island you should be able to complete stamina 10 if not others.


Alvida island is coming once Buggy leaves so get Alvida.

Alvida is red and has good special - damage reduce - 80% - in her 4* smooth form.

Admittedly evolving her will take some time but her special is handy.

Try and get as many of the fortnight islands units as you can.

Franky is an unit you shouldn't miss out on because he would compliment your Marco and Usopp plus he's free.
