Updated July 24, 2026Mega Altaria ex and Greninja Deck Guide in Pokémon TCG Pocket
Scale damage with a full bench while disrupting opponents with early-game item lock.
This deck leverages Mega Altaria ex's scaling 'Mega Harmony' attack alongside Greninja's precise damage to pressure opponents. The win condition involves setting up a full bench to deal maximum damage while using Chingling to disrupt enemy setups. It thrives in matchups where early disruption and consistent damage output matter.
The decklist
How it works
Mega Altaria ex is the deck's primary attacker, dealing 40 base damage with
'Mega Harmony' plus 30 more for each Benched Pokémon. The calculation works
as: 40 (base) + 30 × 3 (bench) = 130 total damage. Its
Psychic energy cost demands careful setup, but
the payoff is worth it.
Greninja provides precise damage with its 'Water Shuriken' ability, dealing
exactly 20 damage to any target once per turn. This helps reach key knockout
thresholds against bulky Pokémon. Its 'Mist Slash' attack offers a solid
Water, Colorless 60-damage option when needed.
Chingling's 'Jingly Noise' attack locks opponents out of Items for a turn while dealing 10 damage. This fragile 30 HP Pokémon disrupts decks reliant on setup items. Its 0 retreat cost makes it efficient for early game disruption.
Matchups
| Matchup | Favorability | How to play it |
|---|---|---|
| Hydreigon variant | Even | Lead with Chingling to delay their setup. Mega Altaria ex needs exactly 3 benched Pokémon to score a one-hit knockout on 130 HP targets. |
| Mirror match | Even | Bench management is critical. Use Copycat to refill your hand after both players dump resources. |
| Water-based decks | Even | Use Greninja's ability to apply consistent 20 damage per turn against key targets. |
Tech options and swaps
The flex slots are Cyrus, Copycat, and Lisia. Cut a Copycat for a second Cyrus if facing many evolution decks. Against aggressive decks, swap Lisia for a second Training Area.
How to pilot it
Dig hard with your draw cards for Swablu or Froakie. Turn 1: Play Chingling to disrupt or bench Swablu. Turn 2: Evolve Swablu if possible, or use Greninja's ability. Turn 3: Attack with Mega Altaria ex if set up. Energy sequencing: Attach to Greninja first, then Mega Altaria ex.
