Mini-momentum? Lol, keeping the spell attack makes it a bit weaker, in fact. Fire has Explosion and can handle with shields like dusk mantle and dim shield, while the reflective ones are imaterial, at least. My feeling is that this will be a broken combo.
Congratz, zanz, nerfed Fire cards just before giving it a good buff, heh? Clap, clap, clap.
I would suggest this skill auto draining 1
per turn, but now Im not convinced its enough to balance it.
Edit: again, should this one really belong to fire?
