I thought that I could pull Apocalypse in 115 mutant/skill crystals, 67 6* crystals, dozen+ nexus 5*/6*, 3 6* class nexus and countless grandmaster crystals, but no luck.
So I'm wondering if anyone knows a pattern or prediction when he might be coming to a featured crystal again. Ready to drop 10,000 units trying to get him [and yes, I know there is a better usage of my units]. Last time he was in arenas was 3/22/2021 if that matters. I also know that there probably isn't an answer, but that's why I'm requesting the help of the following. . .
