@Ura:
I just did a recruit and got an evolved Buggy.
I also fought my first monday turtle swarm at extra island and farmed quite a lot.
I'm using Smoker as my captain right now.
smoker is not a good captain overall, somebody with at least 2x attack (better if possible) is what most of the content need. See if you can make a team with your characters
I'm gonna say some parties you can make (since you seem new)
first: do not pull yet, save gems to the sugofest wich is coming
second: evolve your usopp into golden pound (the one that requires a crab) and keep him there, trust me
basic teams setup - characters you should farm/ use if you have
farmable:
slashers: arlong captain until you can get mihawk, - arlong, kuro, buggy, zoro, tashigi, morgan / vista, shanks
fighters: zeff captain, - sanji, ruffy, ms valentine / mr 2, marco
green: zoro captain, - smoker, hatchi, django (not that good so far), mihawk (when you get the chance) / Izo
red: lufffy g2 captain - alvida, arlong, morgan, mr 5 / blamenco, whitebeard
purlple: buggy captain - Nami, krieg,/vista, ROBIN
zombie party: vivi or laboon captain - high attack low Hp units like ms monday
pullable:
blue: ace or jozu captains - kuro, tashigi, sanji
yellow: marco or shanks captains - usopp (dial) , mr 2 , vivi
purple: nami v2 (fine tempo/happines punch) or vista (both better than buggy), and even better if you have a robin - its one of the strongest teams so far
zombie : zoro V2 (wolf flow or lion song - wolf flow is better for the special and reduced HP)
independent: luffy gear 3, whitebeard and in the next sugofest killer
