I spent 2 SC and got a min cost 4/5 SU Belinda, with all my time and energy free to spend on Monday daily which got me 4 tin cans. Just about the most successful a farm event as I've ever spent SC on. I am 100% tapped on fodder units, plat fairies, almost all my silver fairies, and most of my gold fairies as well though. Belinda is CC70 already so I need the rest of the week to farm, CC a Cali, and then I can awaken Belinda before the next event.
Is there any event that just drops faeries like they're in season? I'd unlock another rax and then just go nuts if I could stack it full of plat fairies.
