my friend uses this strategy and i tried it, it worked for me:

for expert map you use a full kiwame team (basically a night team) to run waves 1-9, then you use a full tachi + ootachi team for the last node. this generally allows you to pass the night battles well and ensures a rank A to get ookanehira on the last wave. May be a little risky if your kiwame swords are lower level than 37.

As for the sword slots, unless you buy more with DMM points you'll be stuck with 50. Try getting rid of some swords that you don't want (usually those easily obtainable like level 1 tantous you never use) to make space for new swords that you want.

To unlock the fourth team you need to complete expedition D-4, which is the fourth expedition on the fourth map.
