Yesterday I was stuck all day on Avenging with more than 20 losses, then I decided using Ultimate
Today I got pass Ob and Zeus easily with Spartan, then through Crusader and Gold by Diamond. On round 30, I used Parakeet and Fruitful, both came very close and finally Elf took Warrior Queen by one big Bashhhhhh Green/Yellow worked for me.

Thank you guys for suggestions, congrats everyone hatched your new egg and good luck to those still battling
