So, will post the units I keep after my four multis (unevolved means that I already evolved the unit and keep the unevolved version):
Barto
Elizabello
3d2y Franky
SW Franky (unevolved)
2x Smoker (evolved and unevolved)
Bastille
2x Maynard (evolved and unevolved)
Abdullah and Jeet (unevolved)
2x Log Nami (evolved and unevolved)
Tashigi
Sentomaru
Kuina
Genzo
Usopp Pirates
17 units I keep out of 44 is a really good sugo for me.
I was lucky to get 3d2y Franky and especially Elizabello because I pulled for him when he first came way too much and didn't get him back then.
For Barto I need to think of a nice team though...
