On the other hand, if we convince people to be original then there'll be less need 'to' fix it.
Arena is interesting, and in my experiments with my decks I'm noticing that the success of a deck is very proportional to the amount of fire in said deck. Even without doing Immorush or SoG and with a Fire Buckler as the oracle card, arguably the worst oracle card for it, my deck is still 6-0 so far. So it seems any fire rules. not just firestall and immorush. Of course, that might partly be because I focused in a perhaps less tapped into obnoxious feature.
(Also we know that the rest of them on the top page are either pandebonium, speed poison, or novarush)
