Sorry I didn't answer this sooner. I was studying for SAT and didn't know this was asked.
First off we'll take out the Poliwrath line, seeing as there are some more powerful Water types we can get instead. We'll also take out two of the Zekrom, seeing as they damage themselves so quickly having four will make you run out of prizes far to quickly. We'll also remove both of the N cards and one of the Twins.
We'll then add three Cubchoo http://www.serebii.net/card/emergingpowers/028.shtml and two Beartic http://www.serebii.net/card/emergingpowers/030.shtml These guys are faster to get out than slow old Poliwrath and that Sheer Cold is an excellent move, stopping the foe from attacking. Then, adding Basic bulk while protecting your Electric types, we'll add in two Cryogonal http://www.serebii.net/card/noblevictories/032.shtml Then to strengthen the Electric side of things we'll add two Electabuzz http://www.serebii.net/card/triumphant/033.shtml and one Electivire http://www.serebii.net/card/triumphant/020.shtml This should do it for your Pokemon.
We now have space for four more cards. The first thing to do is add in two Interviewer's Questions http://www.serebii.net/card/calloflegends/079.shtml to get you your energy. Then, we'll add in another Water Energy and another Electric Energy. You can also replace the Cheren with four Team Rocket's Trickery. One less card drawn but you get to discard a card in your opponent's hand. And your deck is then good to go.
