Delta Reign TCG: Mega Rayquaza ex Arrives November 2026
The Pokémon Company has officially revealed Delta Reign, the next major TCG expansion arriving November 6, 2026. This set is all about Mega Evolution, headlined by the sky-dominating Mega Rayquaza ex.
What's in Delta Reign?
- 135+ cards total
- 20 Trainer cards for deck building
- 35+ cards with special illustrations
- Mega Evolved Pokémon including Mega Rayquaza ex, Mega Golurk ex, Mega Malamar ex, and Mega Golisopod ex
- Part of the larger Mega Evolution TCG series that includes previous sets like Black Bolt, White Flare, and Destined Rivals
Why Mega Rayquaza ex Matters
Mega Rayquaza has always been one of the most powerful Mega Evolutions in the franchise. In the TCG, its Delta Storm ability and massive HP make it a format-defining threat. If you're building a competitive deck around Dragon-type or Flying-type Pokémon, Mega Rayquaza ex will likely be the centerpiece.
TCG 30th Celebration Connection
Delta Reign launches alongside the Pokémon TCG 30th Celebration set (September 16, 2026), which features reimagined classic cards including Pikachu ex, Lugia, and Ho-Oh with special illustrations. The 30th Celebration Basic Energy cards by artist YOSHIROTTEN are already previewed at PokémonXP.
Pokémon Legends Z-A Ranked Battle Season 16: Mega Evolution Only
If you play Pokémon Legends: Z-A, Season 16 of Ranked Battles is going to test your Mega Evolution knowledge like never before.
Rules
- Only Pokémon that have Mega Evolutions can be used
- Only Mega Stones are allowed as held items
- Runs from August 27 to September 17, 2026
Unlockable Mega Stones by Rank
| Rank | Mega Stone Reward |
|---|---|
| Rank Y | Greninjite |
| Rank X | Delphoxite |
| Rank W | Chesnaughtite |
| Rank V | Baxcalibrite |
| Rank U | Sceptilite |
| Rank T | Swampertite |
| Rank S | Blazikenite |
This is the first time Legends: Z-A has restricted an entire season to Mega-only rules. You'll need to know your type matchups inside and out, because with everyone running Mega Evolutions, the meta will be extremely tight.
How to Prepare
- Check type coverage — With Mega-only rules, you can't rely on non-Mega counters. Use the PokémonGen Team Builder to make sure your team covers all major threats.
- Study Mega Evolution stats — Look up each Mega's base stats in the Pokédex to find the strongest options.
- Practice type matchups — Take the Type Quiz to memorize super-effective and resist matchups before the season starts.

Mega Evolution Type Coverage: What You Need to Know
With Mega Evolution dominating the 2026 meta across every game, understanding type coverage is more important than ever.

| Mega Mewtwo X | Psychic/Fighting | Ghost, Flying, Fairy | Fighting, Rock, Bug, Psychic |
| Mega Mewtwo Y | Psychic | Ghost, Dark, Bug | Fighting, Psychic |

Building a Balanced Mega Team
The biggest mistake players make with Mega-only formats is picking six powerful Mega Evolutions with overlapping weaknesses. For example, running Mega Rayquaza, Mega Salamence, and Mega Garchomp together leaves your team devastated by Ice-type moves.
The rule of thumb: Never have more than two Pokémon weak to the same type on your team. The PokémonGen Team Builder automatically flags shared weaknesses so you can fix them before battle.

Based on the current meta across Legends: Z-A Ranked, Pokémon Champions, and Pokémon GO Raids, here are the top Mega Evolutions to invest in right now:
