Deck Mechanic trachy
Note: I don't really care if you have the cards or not. I don't have psychic powers which tell me which cards you do or don't have.
Well you have way too few Pokemon and way too many trainers. You also are missing two cards.
Let's get rid of Prof Elm, Interviewer, Flower Shop, Revive, and Potion. This gives you space for thirteen more cards. You can do a lot with that. As always, three more Pokemon Catchers. This should help you out a lot. Then let's add in two more Pokemon Communication, bringing the total to three. Then, take out a Cheren and add in a Rocky Helmet http://serebii.net/card/noblevictories/094.shtml . This attached to Samurott will leave your opponent not wanting to attack it at all. We now have space for eight more cards.
Okay, now onto the Pokemon. There isn't much problem here besides the incredibly low number of them. Let's add in an evolution line. I would suggest adding in the Emerging Powers Beartic with the Sheer Cold attack http://serebii.net/card/emergingpowers/030.shtml . This guy is amazing, 130 HP, Sheer Cold stops the foe from attacking, and Icicle Crash gives you an attack to take down Grass types with. Let's take out a Magikarp and a Gyarados and add in four Cubchoo http://serebii.net/card/emergingpowers/028.shtml and three Beartic. Now we have space for three more cards. I like the look of that Final Gambit Basculin http://serebii.net/card/emergingpowers/024.shtml . A solid 80 HP basic that can do 80 for three. Sure, you have the chance of KOing yourself, but that 80 damage is worth the risk. Plus, you have an extremely solid Flail attack that can do up to 70 for one and only one retreat cost. Then, add in one Ice Shard Cryogonal http://serebii.net/card/noblevictories/032.shtml . This should decimate Fighting decks in the early game. And that is helpful, seeing as they have some of the most powerful cards in these sets. Finally, let's add on a colorless evolution line. This should help you with mixed decks of the Electric+Steel nature. I would suggest the B&W Cincinno line http://serebii.net/card/blackwhite/089.shtml . Replace your Gyarados for a Cincinno and your Magikarps for Mincinnos http://serebii.net/card/emergingpowers/084.shtml .
And your energies look good. Although you can really benefit from some Double COlorless. Replace two Water for two of them.
