GLC

Gardevoir doubles all attached Psychic Energy while Malamar and Xatu serve as an Energy acceleration engine. Add to that the Dimension Valley Stadium and you can power and Latios' Luster Purge for a single Energy or fire off a massive Moon Kinesis attack with Lunatone. If you find yourself 10HP short of finishing off an opponent's Pokémon, Giratina's Distortion Door Ability comes to the rescue while simultaneously fueling Scream Tail's Roaring Scream attack.

Water type boasts some of the highest HP Pokémon in the GLC format, Wailord chief among them. With 200 base HP and Luxurious Cape as an optional attachment, it's almost impossible to knock out in one hit. To help you set it up, the deck relies on impressive draw and search powers of Octillery and Inteleon while Baxcalibur, Frosmoth, and Starmie serve as some of the best Energy acceleration and recovery engines in the format. And even if Wailord were to somehow go down, a plethora of other impressive attackers - Kyogre, Veluza, Wishiwashi - are always ready to take its place.

It's almost inarguable that Grass is one of the most consistent types in the GLC format and this deck takes full advantage. With no less than five Pokémon able to retrieve other Pokémon from the deck - not to mention all the Trainer cards - it's not uncommon to see all this deck's key Pokémon fully set up in 3-4 turns. As if that wasn't potent enough, the deck also boasts very powerful Energy engines: Venusaur's Jungle Totem, which doubles all the Grass energy on all your Pokémon, and Rillaboom's Voltage Beat, which allows you to retrieve Grass Energy from your deck and immediately attach them. This impressive support allows you to set up equally impressive attackers, such as the hard-hitting Torterra and the bulky Brambleghast.
