How to Play Leafeon ex Flareon ex Sylveon ex
Even though there are multiple Energy types on your Pokémon, you’ll actually only use Fire Energy here, since A3b-009 is your main damage dealer. A2a-010’s ability can provide itself a Grass Energy, and it only needs one Grass Energy to attack. Ideally, you’ll charge up A2a-010 early to weaken opponents, then use A3b-009 as your finisher.
Turn 1 Breakdown
If starting with A3b-055:
In most situations, starting with the non-EX A3b-055 is better because its draw support is more valuable early on, especially if you have a weaker hand. Use Collect to draw a card.
If starting with A3b-056:
Starting with A3b-056 is sometimes better when you're going first, since its extra HP can help prevent a Knockout. It’s also a good choice if you already have a decent hand—for example, if you have A2a-010 ready to evolve and secure a knockout.
Early Game
- Having at least two A3b-055 on the board early is optimal, so you can evolve the Benched one into A3b-034 for extra draw while keeping the Active spot open for A2a-010.
- Next, try to find another A3b-055 to set up A3b-009 for later.
- A2a-010 should be your first evolution priority in the Active spot, since it can attack for just 2 Energy thanks to its ability.
- Especially if you're going first, you’ll need to decide whether to use Collect or Bite before evolving. If A3b-055 can survive an attack, you can risk waiting to draw. If not, evolve right away and use its ability if it's Leafeon.
- Bench most of your A3b-055 immediately so you can evolve them, and to protect yourself from PROMO-006 or A2-155. If you're running A2-146, keeping at least one A3b-055 in hand can be helpful if you need to search for something later.
- Because you’ll be drawing a lot of cards, benching or evolving your Pokémon right away is good for avoiding disruptive shuffle effects.
- After you have enough Energy on A2a-010 to attack, prioritize putting at least one Energy on A3b-009 so if A2a-010 is Knocked Out, you can use Combust with just one more Energy attachment.
- As mentioned in my other guides: if you’re planning to reset your hand, it’s often smart to bait a PROMO-006, A2b-069, or A2-155. Keep your hand at four or more if you’re fine with a reset, and below three if you want to avoid one.
Midgame Strategy
- One of the key decision points is managing which four Pokémon you’ll have on the board. Planning your four slots carefully is essential, since you’ll usually want A2a-010 as your aggressive starter.
- The second most important is A3b-009, your main damage dealer. The third spot typically goes to A3b-034 for its added draw support. Ideally, a second A3b-009 is the next best choice so you can switch it in if the first one needs to retreat.
- If you're facing Oricorio, the non-EX Leafeon is definitely the fourth slot—you’ll need it to be able to take Oricorio out.
- Since A3b-066 has two important purposes, try to be more conservative with it. Unless you’re facing an immediate Knockout threat or a A2-150 grab, it’s better to hold onto it, especially if you need the extra damage boost. A3b-066 can be used alongside Red or Giovanni, so it’s important for securing one-shots.
- Retreating to preserve points—such as switching out A2a-010 for A3b-009—can be a strong play, especially if you have another A3b-009 ready.
- Your plan for dealing damage centers on scoring Knockouts with A2a-010 early and A3b-009 later on.
- After attacking with A3b-009, its Combust attack refills its other Energy, letting you attach just one manually to attack again.
Master Tips
- You can retreat a Pokémon to add an Energy to the discard pile, enabling A3b-009’s Combust. For example, if you already have one Energy on A3b-009, retreating A2a-010 with its Fire Energy can make Combust active by giving you one Fire Energy in the discard, totaling up to three if you manually attach again letting you use Fire Spin immediately.
- Similarly, retreating an early A3b-055 to another A3b-055 or evolution lets you evolve and use Combust right away.
- One of the biggest decision points in this deck is Energy management. Sometimes, skipping A2a-010 and going straight into A3b-009 is the better line. Since A2a-010 can gain its own Energy to retreat, it gives flexibility. But remember, you won’t be discarding Fire Energy this way, so you'll need to manually attach all three for A3b-009.
- The same idea applies when charging another A2a-010 or non-EX Leafeon on the Bench. You can choose to load Energy onto the Benched Leafeon so you can retreat the Active and preserve points.
- Preserving points is especially valuable given the high HP on your EX Pokémon. Making smart Energy plays like these, and deciding whether to evolve A3b-056 before the non-EX A3b-055 (unless you’ll need that 30 damage later), can make a big difference. You can also take advantage of losing an EX like A3b-056 deliberately to make A2-155 stronger.
How to Play Red Card & Mars
If You’re Going First
- Against non–Stage 2 decks:
Use PROMO-006 right away to limit their setup—this is when it hurts them most since they’re not combo-reliant and don’t need a 2-card setup. - Against Stage 2 decks:
It might be better to delay a turn. Since they can’t evolve yet, holding PROMO-006 can be more effective—especially after they play PROMO-007.
If You’re Going Second
- If they’ve played all their Basics, it’s usually safe to use PROMO-006—they’re protecting a strong hand.
- If not, hold it—they might already be bricked, and you don’t want to help them reset.
- Against Stage 2 decks, only play PROMO-006 if they’re sitting on 4+ cards—otherwise wait until their hand grows or after a PROMO-007.
Mars Tips
A2-155 becomes stronger later in the game. You can be more conservative early on and play it once you know a Pokémon will get KO’d to increase its impact.
Card Choices
Core
Must-have cards the deck relies on to function.
- A3b-055 – A general starter, since the draw support is usually more valuable early on.
- A3b-056 – Can be a good starter if you already have a decent hand or if you’re going first.
- A2a-010 – Prioritized for early search due to its 2-Energy attack, and also fuels non-EX Leafeon.
- A3b-009 – Your primary damage dealer and the top Energy priority after A2a-010.
- A3b-034 – Increases deck consistency; ideally evolves on a Benched A3b-055.
- A3b-066 – Lets A3b-009 handle almost anything with its damage boost. Healing can also prevent knockout thresholds and synergizes with Combust.
Optional
Cards that can be cut without hurting core consistency.
- A2-020 – Usually not prioritized except against Oricorio.
- A2b-071 – Helps handle higher-HP threats, but mainly used for one-shotting Solgaleo.
- A2-155 – Since the deck is full of EX Pokémon, you can use a game plan focused on reducing the opponent to just 1 card.
- A2-147 – Helps Pokémon stay out of KO range, especially pushing A3b-009 up to 170 HP.
- A2-146 – Makes the deck slightly more consistent by searching for whatever you're missing.
Situational
Techs that only matter in specific matchups.
- A1-223 – More universal than Red, and with A3b-066 adding damage as well, it’s a strong alternative.
- A2-150 – Mostly used to finish off threats that A2a-010 has damaged.
- A1-225 – Helps slow the opponent down or surprise Benched Pokémon that are gaining Energy.
- PROMO-006 – Quite powerful against Stage 2 decks, which are this deck’s main weakness.
Final Thoughts
This deck turns the Eevee line into a flexible, high-powered strategy. A2a-010 provides early pressure, A3b-009 delivers big finishes, and A3b-034 keeps your hand stocked.
Managing Energy and board space is key—play carefully to cover weaknesses and set up strong knockout turns. If you want an adaptable deck that hits hard and stays consistent, this build delivers.
