Spotlight Cards for Inferno X
Mega Charizard X ex
The headline card of Inferno X is none other than Mega Charizard X ex, boasting a massive attack:
-
Inferno X Attack – For just 2 Fire Energy, you can discard any number of Fire Energy from your Pokémon. Each one adds 90 damage to the attack. With proper energy acceleration, this attack can hit game-winning numbers.
Oricorio ex
- Ability – Excited Turbo: Lets you attach an extra Fire Energy from your hand to one of your Benched Fire Pokémon once per turn, provided you have a Fire Mega Evolution in play.
- Attack – Fire Wing: 110 solid damage.
Perfect synergy with Charizard, helping it reach its full destructive potential faster.
Mega Sharpedo ex
- Greedy Fangs: 70 damage + draw two cards.
- Hungry Jaws: 120 damage, but if Sharpedo has damage counters on it, the attack jumps to a huge 270 total.
Other Notables
- Toxtricity (energy acceleration with recoil damage).
- Charmander & Charmeleon to naturally support Charizard lines.
- Weavile, Whimsicott, Moltres and more rounding out the Fire and Darkness theme.
Why Inferno X Matters
For Players
The combination of energy acceleration (Oricorio ex) and scaling damage (Charizard ex) makes this one of the most explosive decks we’ve seen in a while. Expect it to shake up the competitive scene in Japan and, later, worldwide when Phantasmal Flames drops.
For Collectors
The return of Mega Evolutions adds nostalgia appeal while also delivering powerful gameplay mechanics. Cards like Mega Charizard X ex and Mega Sharpedo ex are likely to become instant collector favorites.
For Global Fans
With the English release coming just two months later, players outside Japan won’t have to wait long to get their hands on these cards.
Final Thoughts
The Inferno X set brings everything fans could ask for—nostalgic Mega Evolutions, competitive firepower, and plenty of collectible potential. Whether you’re building a fiery new deck around Mega Charizard X ex or hunting for rare cards, this expansion is shaping up to be one of 2025’s most exciting releases.
