Ferligatr
This is one of the most unique decks in the WoTC formats, in my opinion. Your goal is - counterintuitively - to get as many Water Energy cards into the discard pile as quickly as possible, powering the massive Feraligatr's Riptide attack. To help you achieve that, the deck uses various methods: Feraligatr's Downpour Pokémon Power, trainers like Secret Mission and the hyper aggressive Misty's Wrath, and The Rocket's Training Gym Stadium which forces you to discard any unproductive Energy cards stuck on your Baby Pokémon when retreating. Since Riptide requires you to shuffle the Energy cards back into the deck after use, you need a way to consistently and quickly fish them out. This is where Trash Exchange comes in, effectively allowing you to loop the cards that have already been played.

Arcphlosion
Typhlosion's stackable Fire Recharge Pokémon Power not only unlocks a variety of strategies previously made impossible by Energy shortage, it makes the Pokémon itself a force to be reckoned with since it's able to extremely quickly fuel its own powerful Flame Burst attack.
The most straightforward way to play this versatile deck is of course to simply go on the offensive with Typhlosion. Alternatively, however, you always have the option to shift into a control strategy by depriving your opponent of Energy using Blaine's Charmander's Kindle attack. And if you want to push this deck even further, Moltres Wildfre attack allows you to mill your opponent's deck and leave them without any cards to draw.
Based on Jason Klaczynski's build.

Venusaur
Venusaur's Energy Trans Pokémon Power allows you to arrange Grass Energy cards on your Pokémon however you like, allowing you to preserve the Energy of Pokémon on the verge of being knocked out or quickly powering up any Pokémon's attack. Even better, it allows you to use Pokémon Center without the high cost of discarding Energy since you can just move them to the Pokémon with no damage counters. If you somehow run out, thanks to Rainbow Energy, Mewtwo help you pull the Energy cards out of the discard pile. Since the deck takes a while to set up, Mew is there to help you stall while Promo Venusaur's Pokémon Power allows you to keep Mew free of special conditions.

Sabrina's Alakazam
Sabrina's Alakazam's Psylink Pokémon Power allows for some very powerful attack combos. You can quickly power up Alakazam with Promo 3 Mewtwo's Energy Absorption, snipe your opponent's bench with Promo 12 Mewtwo's Telekinesis, effectively heal yourself with Rocket's Mewtwo's Juxtapose, and inflict massive damage with Sabrina's Kadabra's Life Drain. While most of these attacks are nerfed by a coin flip, Sabrina's ESP gives you a much higher chance they will result in success.
I thought this deck would work better in the Rocket-On since its greatest weakness - Energy Removal - was rotated out in this format. Unfortunately, the deck proved too slow and dished out mediocre damage compared to its contemporaries.
Loosely based on Adrian Cameron's Rocket-On build.
