^ Buy more 4*'s for luna Level them to level 80. Sell them for 20 TE
Buy a level 1 5* if you have the TE
and repeat with 5*'s..
Works for me
I like it, I'm always trying to level my cards for events, but I'm thinking of taking two weeks off and only leveling cards. Especially since a 6* is the only way to improve my current deck. Good advice.
