Way too many cases of just one of a Pokemon in there. Pick just a few lines and focus on sticking with those. Any Pokemon you're partial to besides Kyurem in the deck?
I'm in a debate on who to take out of my deck, for maybe another totodile and feraligatr, I think I may take out tentacruel and zororak, just because I don't get to use them to often. And sometimes they just don't fit in. I was also thinking of maybe buying a kingdra prime, because if he's on my bench I can put the damage counters on my opponents pokemon needed for feraligatr's attack
