I bought all of the 3* abilities when the celestriads were first released during the free summon event. Now I have almost a full slot count and feel I should sell most of these back get the tickets back. I sold all AOE cards and only kept ST and cone attacks, also kept all of the healing cards. I think i want to sell the draw for next rounds(Force?) and keep turn all to(Shift)?... Looking for input and suggestions. Thanks in advance!
