combo

The plan is simple, hit them with Spiritbomb or Honchkrow to add a bit of damage, then use Weaville EX to hit them for 70 DMG. The deck works well in the early game with opportunities arising no matter what Pokemon you start with. All have 1 retreat cost so staying alive is fairly easy. Honchkrow is very useful for picking off those that wish to leave the front line. Obviously Darkrai ex does a far better job in this deck but this is the budget friendly version. The deck is very difficult when the opponent has established a board of tanks and has healing of any kind.  

It's simple: while using Zapdos Ex, which has the potential to deal up to 200 damage with just three Energy, you evolve Froakie to get Greninja. It's a pretty fun combo that, along with the red card and the hand scope, can be quite annoying for your opponent. IMPORTANT: You should only use Lightning Energy since Froakie's first two stages don’t require Water Energy, and for Greninja, you only use his ability. This way, you can deal damage to the benched Pokémon with Greninja while using Zapdos Ex to damage the active Pokémon.

Ideally you'd start with Hitmonlee, Diglett, and Dugtrio. If you're first energy is psychic play Diglett and hope the next one is fighting, otherwise play hitmonlee and start hitting the back line. Once you evolve Diglett, it and Hitmonlee should be able to give enough time to power up Mew ex. Dual energy is inconsistent but since each fighting mon only uses 1 energy it's tolerable. I tried only fighting energy but I found it better for mew to be able to do 20 damage. Especially if its the first mon you draw.

Use Chatot to get your Gyarados out as fast as possible. Burn as many cards as possible from your hand to insure maximum chance for new cards.

Gardevoir to gather energy for Mew/Mewtwo

Use item cards and Professor card to gather the Pokémon you want, the priority order to use (I think) should be: Poke Ball, Professor's Research, Mythical Slab 

Depending on active pokémon of opponent you use either Mew or Mewtwo, example: if your opponent has Charizard, you can use Mew to copy its attac and kill it in one hit

You can use Mewtwo EX both as tank (use Leaf when it is close to die) and also to attack

Fighting energy only! Start with Chatot and cycle through and work to get Machamp on the board as quickly as possible. Aerodactyl is primarily used for control and Mew can be used as a nice counter to Mewtwo decks. A bit slow to set up, but Machop (1 energy) and Machoke (2 energy) can pack a punch on their own as you work up to Machamp if necessary.

The core combo of this deck is having a Mewtwo EX as the active Pokemon with two energies while having a Gardevoir on your bench. This will allow you to put two energies on Mewtwo every turn, letting you play Psydrive every turn. Once this combo activates, there aren't many decks that can tank that much reliable damage.

This Deck needs some versatile thinking, as you can use Brock with both Onix for a quick sweep on the 4th turn (starting second in a match) and surprise your opponent with a Golem fully set up and ready to roll, as well as baiting/ stalling your opponent with a Marshadow trap to tear down their best pokémon (I find it extremely good against Pikachu that gets one-shotted thanks to weakness).
