Everyone asking for 3BP help use Cu

So Almost all the questions seem to be either people asking about team comp, or people giving advice that may or may not be available to F2P players, so fuck it, the F2P people's hero is Cu.
Ideally get all 3 cu with lvl 10 protection from arrows and a support cu. Obviously everyone at max skills is expensive though, so keep in mind its only one turn charge difference if you have them at 6, and only 2 turns different at any lower level. Putting as many cu as possible into your main team with Shana CEs will probably survive just fine. Even subbing one out for Medusa to clear the hands out once she's charged up and potentially stall Ibraki's noble phantasm if she survives that long is still plenty of survivability, aside from them I've got mash coming out occasionally on the order change skill from the plug suit, but that's really enough. Obviously you need them pretty well levelled to reach the 1.5M damage threshold for doing the 3BP to be worth it, but if you just want survival and better efficiency rather than outright trying to do all 6M damage the cu cu train will do you well.
