team help please

Hi guys!!! this is my char.box... i have two questions:
-which team should i use for the mihawk event? i have laboon and a strong vivi friend (lvl 73 atm), which other members should i put in? i think that arlong+black cat pirates is the best option, am i right?

-on which char should i focus for my ordinary team? atm i'm using a slasher team with arlong as captain, but i'm not sure if there are better options...

let me know what do you think!!

Slasher is pretty strong atm.
For Mihawk just put the strongest units u can get in different colours, without having too much hp for vivi to heal at least 50,1% hp.

for the mihawk event, it is better to choose different colours to try to get to the final stage without beeing killed and waste gems, or use red ones to speed up the final stage? i mean, enemies in the 1-4 stages could be a trouble if a choose only red units?

not only red units, will get locked. all different

ok, i'll use different colours then thanks!!

Considering the up coming event just go for laboon and vivi friend. The others you choose this way that all of the teams hp+ship is not smaller than the vivis rcv × 10.
Recommend as filler units crabs.

Probably the best team u can currently build with ur units is a slasher team.

You want in every team to have golden pound usopp but since you already evolved him you want to use sokeking. ( besides mihawk since you dont want to burst him u dony need the extra turns)

The following my recommendation:
Arlong
Zolo
Kuro
Buggy/tashigi/ vivi ( depends ob stats)
Sogeking

yes, i know that golden pound usopp is better than sogeking, but i already evolved him when i discovered it xD but i just got a base usopp, i'm trying to drop a yellow crab so that i can evolve him

Yeah for mihawk just go with laboon vivi team as you don't have any of the other groups that could beat him (g3 luffy/whitebeard). Just for reference, the vivi will need to be fully evolved lvl 70+ to survive against mihawk. Your team's total health will need to be around 4k (that way any level 70+ vivi will always heal you above half and trigger laboon's ability) so keep that in mind when forming your team.

For other stuff I would say going with what soeren recommends for slasher team, I would suggest just going with tashigi out of those three as she is head and shoulders stronger than the other two in stats (again this is for non-mihawk events as going lots of speed against a dex would be foolish).
