Firecell is a 'gmmick' deck that has a similar chance of winning vs AI3 as against FGs. It's only profitable because it has that 20 or whatever percent win rating against FGs. However, there are many gods that it simply has no chance against-- and it's not much of a stretch to lose 20 times in a row if it keeps getting those gods.
Go back to grinding bronze/Ai3/Ai4 (with your previous deck) to get your reserves back up.
Additionally, make sure you're playing the combo correctly, since the deck doesn't work otherwise.
I'm playing it correctly... just never getting to it at FG.
