Good lord, more evidence of how OP this card is:
I built a fat rainbow for my league deck and included two SoFo as well as two fractals. I was testing my deck and, whether I play a SoFo or the AI plays one, the AI targets the SoFo for fractal. All of a sudden there's like four or five SoFos on the field. "Oh, you don't have six EAs to protect your permanents? then you're S.O.L."
Seriously, I don't feel like I can complain enough about how OP this card is. In some ways, I felt the same about SOG in the past, and was happy for the nerf it got. Can't wait for this one to get balanced.
