Looking at the NU stats, Quagsire has really fallen from grace - now it's sitting all the way back at #27!
Sawsbuck has fallen off the face of the Earth at #39 and Charizard at #46. I guess having power and coverage really means nothing when you are that frail.
Serperior meanwhile has risen to #43. Still way off the top 20 where it should be but it's getting there.
Also it never ceases to amaze me the amount of very good Pokemon that see no use: Linoone at #52, Carracosta at #62, Shelgon and Duosion at #70 and #71 and Relicanth at #78.
