Robin/ Ace account for trade

[Rigel_]

Hey everyone,
I have a lvl 35 account with:
lv20 5* Ace;
lv47 4* Robin,
lv37 4* Buggy;
lv22 Tornado Tempo Nami;
lv29 3* Don Krieg;
lv18 4* Bon Clay;
lv10 4* Mr.1;
1 Yellow Elder Turtle and 1 Purple Elder Turtle;
and the 3* basic versions of the other straw hats (except for luffy, who is 4*).

The account has a solid start on both INT and fighter teams.

I don't exactly know what I'm looking for, but the units that are most appealing to me are WB/ Vista/ Marco/ 3rd gear Luffy or 5* Shanks.
