Well, after a bit of fiddling around with this I don't have a problem with the change. It's significantly more unusable in Speedbows now which I find a good thing since I thought it was a bit ridiculous to find this card used in just about every recent Speedbow submitted to the forums. I'm finding running it with Quantum Towers instead of Supernovae work very well. Slower, but still reliable and allows plenty of SoSe usage, just not all at the same time.
Of course, it's still very difficult to use in a Mono Entropy deck without Quantum Towers, and even with Supernova in the deck a lot of expensive cards will seldom if ever get to be played.
