Taking advantage of Kirlia's branching evolutions, you can go for big damage with Gallade or for a more control-type strategy with Gardevoir (and Dusknoir). The deck is very slow to set up which means while you will fall behind initially, making a comeback will be relatively seamless due to Upper Energy.

Try to prevent your opponent from playing any Trainers with Spiritomb's Keystone Seal, ensuring Stormfront Gengar's Poltergeist causes more damage. Alternatively, spread the damage across opponent's Pokémon with Arceus Gengar's Curse and thin out the herd with Gengar LV.X's Compound Pain.

This deck relies on a specific loop trap. Leveling up yor Active Gliscor to Gliscor LV.X causes the opponent's Active Pokémon to become Paralyzed and Poisoned due to Gliscor LV.X's Poké-Power. Next, attacking with Gliscor's Burning Poison returns it to your hand. Lastly, you promote Spiritomb (with Unown Q for free retreat) to lock your opponent out of ways to retreat. On your next turn, simply promote a new Gliscor to Active and repeat the loop. You can ensure a backup Gliscor is ready every turn thanks to the Broken Time-Space Stadium.

Very simply, the goal of this deck is to use Felicity's Drawing to discard three Magikarp as quickly as possible, unlocking Gyarados' Tail Revenge. The rest of the cards are there to help you keep Gyarados alive ans retrieve Magikarp/Gyarados if they're knocked out.

With Luxray GL LV.X's Bright Look and Garchomp C LV.X's Dragon Rush there is basically nowhere your opponent's Pokémon can hide. The deck is also extremely quick to set up primarily due to a combination of Cyrus's Conspiracy (powerful card search) and Energy Gain (lowering attack cost).

Regigigas LV.X with Snowpoint Temple and Expert Belt is almost impossible to KO, at least in a single turn. To further ensure this doesn't happen, use Mesprit's Psychic Bind to slow down your opponent while healing Regigigas LV.X with its Sacrifice Poké-Power.
