I got the lion too. I used mammoth and chameneon
Got him with chromadile and skyger after i failed ten times trying for frankenswine or pegasus i decided to change and throw this two in the den and finally got some luck!
I might finally have this guy breeding. That is to say, I mated a daredevil and a chameneon and the result is 15 hours. So it's this or a fourth cosmic phoenix. I like my cosmic phoenixes, but I'd REALLY rather be able to cross off this from my to do list. I've only managed to breed ONE new animal in the last MONTH (the elephantum).
ARGH! It's a fourth phoenix! *Bangs head on wall.*
