I really like this deck and Seravy's guide. I have used this deck in the past week and won about 60 about upped cards. I only started with 6 RoL upped. A few things I have noticed.
1. SoG's are not worth it. I think having a shard saved me once and gave me about ~3 EM's. Getting a lobotomizer, hope, RoL, and fractal is so much more important than SoG's. If you do not have these pieces on the easy gods, you still might lose.
2. I have had terrible luck against Elidnis. I still play him, but he puts down more EB than Ferox. I have better luck against Ferox. Just play 12 RoL and then play Dragons. However, this is a long drawn out fight.
3. I think playing against Decay is worth it.
4. I have started to play against Eternal Phoenix. Depending on your hand, it is worth it. You need to be able to fraction ROL's when necessary.
5. I can't win against Dream Catcher or Rainbow.
6. I have won against Neptune, but he is not worth it.
7. I definitely lose a lot playing this deck, but it is efficient. This deck is very efficient. I don't mind trading numerous loses, electum, and decreased score for upped cards.
