If you check the original list, there is no Empoleon line. But, I would say use an Octillery Glalie deck for BRs, since they both have attacks that completly destroy the main tools of the format(trainers and special energy). JMO. But, back to the original deck list. I think it is, currently, a 6, 7, or maybe and 8 out of 10. I think you should ditch the Glalie in the Walrein deck, and shove in a decent Empoleon line, with, of course, 1 Lv.X. Again, these are only my opinions.
