Today, I’m sharing my original, custom-built Mega Diancie deck!By using Mega Gardevoir, which only requires 2 Energy, you can quickly attach 3 Psychic Energy to your benched Pokémon. This lets Mega Diancie rapidly accumulate damage and hit for 240 damage or even more in a single strike!However, unlike most players, I am only running a 1-1 Mega Gardevoir line this time.The reason is simple: after playtesting it in actual matches, I found that the entire deck runs much more smoothly this way.The entire Pokémon lineup consists of:Meloetta × 2Mega DiancieRaltsThat's a total of only 4 Basic Pokémon. Combined with Meloetta's Ability, you can consistently search for Psychic-type Pokémon every turn, significantly boosting your setup speed in the early game. In the best-case scenario, you can get Mega Gardevoir rolling as early as turn 4.I also added a [Peppa (Paipa)] (or Peppa's Search) to reduce the chance of bricking with Rare Candy, taking the deck's overall consistency to the next level.If you like exploring new decks and want to experience a playstyle different from the meta, I hope this video brings you some new inspiration!If you want, let me know:What other Trainer cards you are considering for the listWhich matchups you are struggling withI can help you fine-tune the deck or adjust the ratios for your next tournament!
