Miraidon ex and Tapu Koko ex Deck Guide for Pokémon TCG Pocket

To pilot the Miraidon ex and Tapu Koko ex deck in Pokémon TCG Pocket, open with Tapu Koko ex in the Active Spot to attack early and accelerate Lightning Energy to your bench, then switch into Miraidon ex to deliver heavy finishing attacks.

Core Strategy and Role Distribution

This Lightning-type archetype relies on a dual-threat setup within the game's 20-card deck limit. Because matches end when a player claims three points and Pokémon ex yield two points when knocked out, you must avoid losing both of your main attackers. Tapu Koko ex serves as your opening combatant to absorb early trades, while a benched Miraidon ex acts as the primary sweeper once powered up.

Card	Role	Strategic Purpose
Tapu Koko ex	Early Attacker & Accelerator	Pressures opposing basics starting on turn two and accelerates Energy to the bench
Miraidon ex	Primary Sweeper	Takes heavy late-game knockouts to close out matches
Professor's Research	Draw Supporter	Draws two cards to dig for basic Pokémon and mobility items
Poké Ball	Search Item	Fetches Basic Pokémon to prevent opening turn bench starvation
Sabrina	Disruption Supporter	Forces the opponent to switch, isolating weak basics or high-retreat targets
X Speed / Leafy Camo Poncho	Mobility & Protection	Reduces retreat costs or shields attackers to facilitate clean bench pivots

Run two copies of Miraidon ex and two copies of Tapu Koko ex to establish consistent opening hands, filling the remaining slots with drawing, switching, and search items.

Turn Sequencing and Priority Actions

Executing the correct sequence during the first three turns prevents dead turns and sets up continuous attack pressure.

Turn 1: Prioritize placing both Tapu Koko ex and Miraidon ex onto the board. If Tapu Koko ex is active, attach your generated Lightning Energy to it. If you open with Miraidon ex in the Active Spot, hold off on overcommitting attachments unless you hold an X Speed to rotate Tapu Koko ex forward on the following turn.
Turn 2: Attack with Tapu Koko ex. Use its offensive presence to chip opposing active Pokémon and start accelerating Energy onto your benched Miraidon ex. Play Poké Ball or Professor’s Research if your bench lacks a secondary attacker.
Turn 3 and Beyond: Check opposing HP thresholds. If the opponent's active card enters knockout range, or if Tapu Koko ex is about to be eliminated, prepare to transition. Play Sabrina to pull forward high-retreat targets or vulnerable support cards, or retreat Tapu Koko ex with X Speed to send in a fully charged Miraidon ex for a decisive knockout.

Energy Allocation and Pivot Timing

Because Pokémon ex award two points upon defeat, managing your retreat timing determines whether your opponent reaches the three-point threshold.

Retreating to Preserve Points: If Tapu Koko ex takes heavy damage but Miraidon ex has enough Energy to secure two consecutive knockouts, use X Speed to retreat Tapu Koko ex to the bench. This prevents the opponent from claiming two easy points.
Sacrificing for Board Momentum: If Miraidon ex is completely ready on the bench and retreating would deplete your active Energy reserves, leave Tapu Koko ex in the Active Spot. Let it absorb a major attack so Miraidon ex can enter battle with full health and sweep unhindered.

Matchup Approaches

Against Water Decks: Leverage the built-in Lightning weakness advantage. Both Tapu Koko ex and Miraidon ex reach knockout thresholds earlier than normal, letting you play aggressively from turn two onward.
Against Stage 2 and High-HP Decks: Use Sabrina early to disrupt evolving Basic Pokémon before they reach their Stage 2 forms. Against bulky targets with 160 or more HP, strike first with Tapu Koko ex so Miraidon ex can close out the elimination on the following turn without absorbing two consecutive hits.
