CC53, 3/5, -4 CR for me, with 3 copies waiting for plat fairies. Then I think I'll just need 3 more copies to hit CC70. Spent today on G-tier Spirit Rescue to try n get more fairies, but the first run was a no-drop and the 2nd only gave me 1 plat fairy -_- fml
55/7 has been good to me, I think Lumaria dropped every run so far.(~4 times) If I have leftover copies after I get her to CC70, I'll just throw them at Marle.
Edit: CC70, 5/5, mincost now. Glad 55/7 has such a high drop rate for both Lumaria and plat fairies because it took a decent amount of copies for that last CR and SU. Ended up doing 2 copies + 2 fairies since I was getting them almost 1:1 and had no luck in the ~4 Spirit Rescues I did earlier(other than 1 run which got me double rainbows+1plat+2black). Got the last CR at CC66 and the last SU hitting CC70, leaving 1 spare copy that I can throw into Marle later. Silver drop rate was really good for me too and i got 3x Harissa and 4x Rosalie out of todays ~8 runs.
