Solid deck strategy. I'd take 2x Faeflames over 2x Axewomen any day of the week. Especially in this deck given how many cards benefit from frenzy, but FFBs are also amazing for gaining early board control (even if going 2nd). Just something to consider.
You are not wrong, Faeflame is a seriously great card and I might try switching that up. I was hesitant to change it when it was working so well (and I only pulled my first faeflame at level 250 or so and I am not even 300 yet lol!) but the more I see things like this the more I want to see if it will make it work even better!
