Funny thing is, I really don't need to spend anything else on this team. PVP is pointless now. Just hang around the top of a league in Champion and collect weekly coins; you dont even have to play. You can load up a bot and just exit out and you are entered for the week (found that out by accident one week).
With an explosive borrow, the team gets perfect trophies on every raid currently. The only reason to level now is like the 40 killaton, to loan out.
