DialgaChomp is a competitive deck archetype in the Pokémon Trading Card Game. Developed after the release of the Supreme Victors expansion, the deck's name comes from a combination of Dialga G LV.X and Garchomp C LV.X, the deck's two main attackers. The deck has placed well at numerous tournaments, and, although LuxChomp is a far more common choice for tournament competitors, DialgaChomp continues to be the deck of choice for some of the game's best players. It is recognized for allowing the player an incredible number of options, as well as having virtually no downright poor matchups.
DialgaChomp really has no designated starter Pokémon. Dialga G is often considered the best Pokémon to open the game with, but Unown Q or Poké Turn can be used to negate almost any undesirable start. Early in the game, the DialgaChomp player will often stall the opponent with Dialga G's Deafen attack, which, for , does 10 damage and prevents the opponent from player Trainer cards. While repeatedly Deafening, the deck attempts to get out benched Dialga G and Garchomp C with sufficient energies attached, at the same time stockpiling Poké Turns and Power Sprays in the hand through the use of Cyrus's Conspiracy.
Once the DialgaChomp player has sufficient resources to begin attacking with either Dialga G LV.X or Garchomp C LV.X, he or she will often break the Deafen lock in favor of taking prizes. At that point, the opponent often has few cards to work with due to the brutal earlygame combination of Deafen and Power Spray, so DialgaChomp can frequently take all six prizes with little resistance. Garchomp C LV.X's Dragon Rush attack does 80 damage to one of the opponent's Pokémon for , but forces the player to discard two of those energy. Dragon Rush's energy requirement is often satisfied by one Double Colorless Energy and one Energy Gain, allowing the DialgaChomp player to charge it in one turn.
