Great Ball of Frozen Fire

Goodness gracious, this is the strangest thing you've seen in many moons. It looks like someone hurled a mystical fireball at an opponent, and that opponent hurled a mystic iceball right back, and somehow the two of them became fused together. Flames crackle inside of it, and frost crackles on the outside. You could snap trying to pop this thing open!
