Yo Israel.
Congrats with the 3rd place.
And, cool that you have been a deck mechanic.
Well, I have a deck here, that I want to get tweaked to an KILLER deck.
Hope you'll take the time to fix it ;)

Okolly Dokolly Neighborino:

The first thing  that you should do is add a couple of TR Zapdos and drop the grass energy, because12 Pokemon aren't enough in this environment. I believe that Lass is a better trainer than RSA if you're not playing trap, and that 4 Oaks are required. The rest of your deck looks pretty solid, so lets not mess with it. Well, maybe a little bit.

The Final Deck:

I didn't like the idea of only having 12 Pokemon and added a couple of TR Zapdos.

Lass is a better trainer than RSA if not running trap and it requires you to play 4 Oaks to be able to recover before your opponent.        I don't like the idea of only using 2 Item Finders because I usually run 4 in my decks (Item Finder Good. No Finder Bad).

22 Energy is too much energy for this type of deck and Scyther doesn't require you to play any grass.

Your deck should do a lot better now and if it doesn't is not my fault MMMK :)
