Best Pokemon TCG Pocket Mega Gyarados ex deck guide: Strategy breakdown
All Mega Gyarados ex variants as seen in the game (Image via The Pokemon Company)1) Mega Gyarados ex
- HP: 210
- Attack: Mega Blaster - 140 Damage
- Effect: Discard the top 3 cards of your opponent’s deck
- Energy Cost: 3 Water + 1 Colorless
- Retreat Cost: 3 Energy
Mega Gyarados ex is the main character of this deck. Its Mega Blaster not only deals a solid 140 damage but also discards your opponent’s deck, rendering a portion of the deck useless and limiting their options. With 210 HP, it can withstand most single attacks, making it one of the more durable cards in the current format.
2) Mantyke & Manaphy
Mantyke and Manaphy are your early-game support. They generate Water Energy and distribute them on your bench. Because Mega Gyarados ex is Energy hungry, these cards are essential to take the lead.
- Mantyke’s Splashy Toss: Attaches one Water Energy from your Energy Zone to one of your Benched Basic Pokemon.
- Manaphy’s Oceanic Gift: Selects two Benched Pokemon and attaches one Water Energy to each from your Energy Zone.

While Mega Gyarados ex is enough in most matchups, it will hit a wall against Oricorio (Pom-Pom). In this situation a standard Gyarados acts as your situational backup.
Both Gyarados (Mega Rising) and Gyarados (Genetic Apex) are excellent choices:
- Genetic Apex Gyarados’ Hyper Beam deals 100 damage and discards a random Energy from your opponent’s Active card.
- Mega Rising Gyarados’ Hammering Tail also hits for 100 damage but discards the top card of your opponent’s deck.
Both require four Water Energy, so your pick depends on whether you prefer energy disruption (Genetic Apex) or deck milling (Mega Rising). The Genetic Apex version has a slight edge with 10 more HP.
