Best Pokemon TCG Pocket Latios and Latias (Secluded Springs) deck guide: Strategy breakdown

All Latios and Latias variants as seen in the game (Image via The Pokemon Company)

1) Latios

• HP: 110
• Ability - Fantastical Floating: If Latias is in play, Latios has no Retreat Cost.
• Move - Luster Purge: 120 damage for three Psychic Energy (discard all Energy once the move is used).

Latios serves as your main attacker. Luster Purge's 120 damage disrupts opponents' plans or secures knockouts, but its heavy Energy cost and their discard makes it hard to sustain, similar to Pikachu ex from Shining Revelry.

This is where Latias becomes crucial. Thanks to its ability, you can swap it in and out of play freely when Latias is on the field. The strategy works like a “hit-and-run” approach: Latios delivers the blow, retreats safely, and waits to recharge for the next time it's ready to hit.

2) Latias

• HP: 90
• Move - Crossing Flights: 20 damage for one Psychic Energy (40 if Latios is on your Bench).

Latias plays a more supportive role, holding the line while you're refueling Latios' Energy. For just one energy, it deals up to 40 damage, solid chip damage that sets up knockouts for Latios. Additionally, since it needs only 1 Energy, you get the freedom to focus your resources on powering up Latios.

3) Gardevoir (Genetic Apex)

• Ability - Psy Shadow: Once per turn, attach a Psychic Energy from your Energy Zone to your Active Psychic Pokemon.
• Move - Psyshot: 60 damage for two Psychic and one Colorless Energy.

Gardevoir, as always known to be, will be the deck’s support providing energy acceleration. Its Psy Shadow ensures Latios goes to the front faster and takes lesser turns to charge up. With Gardevoir's ability, Latios’ heavy energy demand becomes far more manageable, making the deck smoother and more reliable.

The Latios and Latias revolve around synergy, with Latias setting the stage while Latios closing the fight. While it may not outpace the giants in the meta, it’s a creative and fun deck to try out the Eon Duo in Secluded Springs.
