I got this team for pseudo-unlimited QCK clearing. The strategy needs lvl 2 cooldown sockets. In the first stage just swap WB&Marco to Marco, then just stall. Stage 2 clear while healing using one magellan special. Stage 3, Turn 1 use Barto to heal back up and the other Magellan Special. Use WB&Marco when you feel to (Just pop him when you need extra healing as you'll have to tank a hit). Then is just stalling using Barto and Gotti while waiting for Garp's special to be able to clear the stage. Still haven't tested in high lvls but IMO is a pretty solid option. In my test run team had +70K HP so i think that you'll be able to tank a lot. You don't start at full HP but its not a huge problem since Barto heals 50% crews HP and the other healings are huge as well.
