Diamond & Pearl / Platinum

Gardevoir's Telepass copies the opponent's Supporters while Gallade flips prize cards face-down to fuel massive Psychic Cut knockouts. Flexible, consistent, and dominant for two seasons.

Spread damage with Kingdra's free Spray Splash every turn, then finish with Dragon Pump. Cheap attacks and a low energy count made it lethally consistent.

The apex SP deck: Luxray GL LV.X drags up easy targets with Bright Look, Garchomp C LV.X snipes the bench, and Power Spray shuts down the opponent's Poké-Powers. Speed and disruption in perfect balance.

Dialga G LV.X's Time Crystal switches off all Poké-Bodies, crippling decks that depend on them, while Garchomp C and stall tools control the pace.

Tail Revenge deals damage for every Magikarp in the discard pile — for zero energy. Dump three Karp, recycle Gyarados, and attack for free all game.
