I second that SoR is too expensive, and not only because it ruins SiG XD.
In reality, one of the main problems with SoR was that it could be spammed on time creatures for a lot of copies of a card when comboed with mitosis. I don't think there are any other examples of abuse for it. This nerf just essentially confines it to time decks, take a purple nymph. These are good targets for SoR as a 4 entropy cost is pretty damn expensive. Now, you are forced to run a duo for something with essentially the same cost (3
in a mono= 3
). Does SoR nymphs need a nerf? Steamies are also great targets for SoR, it made it possible to run them in a mono, which is great, however, if your going to have to run a duo anyway, why not keep fire? It has lots more synergy, as well as PC.
