wasup souper. Here is a new one for you. I call this deck the mulcher. Its related to the hay maker but i have added a little surprise. I have found a use for porygon ( dont lauph to hard ). I will explain my strategy after i list my deck. 
POKEMON 14

3 porygon (rocket)
4 magmar  (fossil of coarse)
4 electrabuzz
3 hitmonchan

TRAINERS 24

3 scoop up
3 switch
2 bill
2 prof oak
2 gambler
4 gust of wind
4 plus power
4 energy removal

ENERGY 23

7 electric
7fighting
8 fire
my strategy is simple. attack as fast as i can with magmar hitmonchan or electrabuzz And when porygon shows up I switch him in using scoop up or switch or just by retreating my active pokemon. Then i change there weakness to what i want it to be and switch porygon back out. I think the other trainers explain themselves. This deck is easy to use and is very fast. so far its undefeated but im sure it can be better. Feal free to add or take away any cards to help my strategy. I have battled against many types of decks at pokemon league the only one that gave me trouble was a psycick stall deck.


P.S.
sorry about the spelling i dont have spell check.

Overview

Basically a Haymaker variant that tries to take advantage of weakness by changing your opponent's weakness to what you're using. With that in mind, three colors seems really uneccesary. The big reason to use three colors is to take advantage of weakness, but Porygon takes care of that.

Pok閙on

I'd drop a color first. This'll help the deck flow more smoothly and free up a lot of space. Porygon's covered weakness, so now we consider resistance. Nothing resists fire, and Ground types aren't too popular. Fighting is resisted a LOT, so Hitmonchan's probably the best choice to drop. Take out him and his Energy. Past that, the choice of colors doesn't matter too much, so I'll just stick with what was given- Buzz and Magmar. Throw in three Scyther, too, and stick in a fourth Porygon, since he's part of the strategy.

Trainers

Since everything here's basics with fairly low Energy costs, Scoop Up should work better than Switch, so take out the Switch. You need more card drawing too. Let's drop the Gambler for the more reliable card drawing Trainers, Bill, Oak, and Com. Search. Add two Bill, another Oak, and three Com. Search. Four Gust is kind of heavy, let's cut that down to three and add three Super Energy Removal.

Energy

The Fighting Energy goes, and add three DCE for Scyther, Porygon, and 'Buzz's retreat cost. 
Pok閙on (15)
4 Porygon (Rocket)
4 Magmar  (Fossil)
4 Electabuzz
3 Scyther

Trainers (27)
3 Scoop Up
4 Bill
3 Prof. Oak
3 Com. Search
3 Gust of Wind
4 Pluspower
4 Energy Removal
3 Super Energy Removal

Energy (18)
7 Electric
8 Fire
3 Double Colorless
Porygon can also be used to change the opponent's type to itself, and then confuse them. If they take confusion damage it'll be 40 instead of 20. Should work better for ya. Good luck!
