I have found that by correctly using several neo cards, fighting decks especially, but all decks can pump up a pretty good arsenal.

 

Elekid-for one thing he requires no energy to attack, but can do 20 damage even from your bench, which means he can pump up any deck even from the bench.  And if he is gusted out, he has the standard baby rule making him hard to hit.

 

Guraiga-This dude is another scyther but made for fighting.  For one energy he can poison for 10, then do 20 the next turn for 2 fighting.  This equates to 40 damage for 2 in 2 turns, that's better for scyther, and then every turn you do 30 for only 2 fighting energy, whoa!! The comeback for fighting is looking good for mono fighting guys like me!!!

 

Rantaan-this fish can do 20 damage for 2 L energy but, has the pokemon power to do unlimited damage if you put enough water energy on him.  This means that he can have the most powerful attack in the game.

 

Pii-this sucker is a hyper-oak man!! for one measly energy he can let you shuffle your hand and get 7 fresh cards, the only draw-back is that your turn is over.

 

Clefairy-the neo version is the ultimate energy grabber, he let's you flip a coin for every pokemon in play, and get energy for each heads!! All I can say is hello ultra-ultra-compsearch-for-free-baby!!!

 

Ecolo Gym-this is great too, but a double edged sword.  This card allows all discarded energy to be returned to you and your enemies hand for the rest of the game when it is discarded.  You could play with maybe 8 or 9 energy without a problem. This is the ultimate solution to the fire energy burning problem.  Those discards melt away.  The possibility with charizard is a Double Colorless Energy, fire spin it to fire type, then fire blast and discard it back to your hand, for the same thing next turn.

 

I am sure with these awe inspiring cards, people will be having much tougher decks, and I hope to see some in the future!!
