Pokémon Trading Card Game Pocket: Ruler of the Skies Card List Guide
Mega Rayquaza ex headlines Ruler of the Skies, but the expansion’s real scale is its 233-card checklist: 155 standard cards followed by 78 secret rares. Released for Pokémon Trading Card Game Pocket on July 29, 2026, the B4 set pushes Mega Evolution, Dragon lines, storm-themed artwork, and premium alternate treatments much harder than a typical single-card chase.
The efficient target order is clear. Build around the four-diamond Mega versions first, then decide whether Mega Rayquaza ex’s immersive #203, Mega Metagross ex’s rainbow #200, or Mega Gallade ex’s rainbow #198 is your collection endpoint. The secret pool is large enough that opening packs without a defined goal can scatter progress across dozens of full arts and foil variants.
Ruler of the Skies B4 set size and rarity breakdown
Ruler of the Skies uses a clean numerical split. The standard checklist runs from #001 through #155, while the secret-rare section begins at #156 and ends at #233. That makes the maths useful when tracking completion in the Card Dex: 155 standard slots, 78 secret slots, and 233 total cards.
| Checklist section | Card numbers | Cards | What it contains |
|---|---|---|---|
| Standard set | #001-#155 | 155 | Regular-print Pokémon, Mega ex cards, Trainers, and the core playable versions of the expansion’s headliners. |
| Secret rares | #156-#233 | 78 | Full arts, immersive cards, rainbow treatments, premium ex variants, and alternate Trainer foils. |
| Entire B4 expansion | #001-#233 | 233 | The full Ruler of the Skies collection and deck-building pool. |
Secret rares account for roughly 33.5% of the total checklist. That percentage describes the collection itself rather than a pack pull rate. Pack results still follow the expansion’s booster rules, rarity distribution, and the new four-diamond-or-higher guarantee category.
Pocket’s symbols matter more than the classic Common, Uncommon, and Rare labels used in older physical Pokémon TCG sets. Standard cards commonly use diamond rarities such as ◆◆◆ or ◆◆◆◆, while premium cards use star-based tiers. Gold stars, full-art frames, immersive vertical art, and rainbow foiling are the visual signals to watch for once the secret section starts.
Collection trap: a standard four-diamond Mega ex is usually the card that advances a playable deck. A full-art, rainbow, or immersive printing is the premium version of that chase. Treat base copies as the gameplay priority and secret versions as the long-term collection layer.
Confirmed Ruler of the Skies card numbers worth tracking
The B4 list includes a broad mix of standard Pokémon, Evolution-focused support, Energy-related Trainers, and secret treatments. These are the named card numbers that define the expansion’s Mega and secret-rare roadmap.
| Card number | Card | Rarity or treatment | Why it matters |
|---|---|---|---|
| #109 | Mega Metagross ex | Four Diamond | The standard playable Mega Metagross ex and the foundation of the card’s collection line. |
| #119 | Rayquaza | Three Diamond | A high-tier standard Rayquaza that sits immediately before Mega Rayquaza ex in the numbered set. |
| #120 | Mega Rayquaza ex | Four Diamond | The key functional Mega Rayquaza ex printing for players building around the expansion’s flagship Pokémon. |
| #156 | Wurmple | Full Art | The first secret-numbered card and a useful marker for where the premium section begins. |
| #157 | Lileep | Full Art | An early example of the set’s wider full-art Pokémon pool. |
| #158 | Kricketune | Full Art | Shows that secret slots extend well beyond headline ex cards. |
| #166 | Clefairy | Full Art | A mid-secret full-art target for collectors filling the complete #156–#233 run. |
| #167 | Ralts | Full Art | A natural companion target for players collecting the Gallade Evolution family. |
| #187 | Mega Metagross ex | Full Art / Two Gold Star | The premium illustration version of Mega Metagross ex. |
| #188 | Mega Rayquaza ex | Full Art / Two Gold Star | The first secret version of Mega Rayquaza ex and the cleanest premium upgrade from #120. |
| #198 | Mega Gallade ex | Rainbow / Two Gold Star | Mega Gallade ex’s marquee secret-rare target. |
| #199 | Hoopa ex | Rainbow / Two Gold Star | A premium ex chase outside the three headlining Mega cards. |
| #200 | Mega Metagross ex | Rainbow / Two Gold Star | The most prestigious Mega Metagross ex treatment in the known B4 card line. |
| #203 | Mega Rayquaza ex | Immersive / Three Gold Star | The top Mega Rayquaza ex collection target, built around a full immersive presentation. |
The remaining numbered slots still matter for full completion, especially the Trainer secrets and other full-art Pokémon. The Card Dex is the best place to track those gaps in-game, particularly after the update that registers cards appearing in multiple booster packs for every relevant pack. That registration improvement also applies retroactively to cards already owned.
Mega Rayquaza ex has the deepest chase path
Mega Rayquaza ex is the expansion’s most complete premium line. It starts with the regular Rayquaza #119, advances to the core Mega Rayquaza ex #120, then branches into the full-art #188 and immersive #203 treatments.
- Rayquaza #119: Three Diamond standard Rayquaza.
- Mega Rayquaza ex #120: Four Diamond base Mega and the practical target for deck construction.
- Mega Rayquaza ex #188: Two Gold Star full-art secret rare.
- Mega Rayquaza ex #203: Three Gold Star immersive secret rare and the premium completion target.
For collectors, #203 is the card that completes the set’s central visual story. For players, #120 is the important first pull because it provides the actual Mega Rayquaza ex card needed for the deck. The #188 and #203 versions share Mega Rayquaza ex’s function while changing its presentation and rarity tier.
Secret Missions also make the Rayquaza line unusually valuable to track. Missions tied to Mega Rayquaza ex variants can award resources such as Wonder Hourglasses and Shop Tickets, creating extra value from a pull that already advances either a deck or a collection.
Mega Metagross ex and Mega Gallade ex chase priorities
Mega Metagross ex: the three-print collection
Mega Metagross ex also has a clear three-step rarity structure. The four-diamond #109 is the functional starting point, #187 is the Two Gold Star full-art version, and #200 is the Two Gold Star rainbow finish. Its associated Beldum and Metang line gives the Mega a straightforward Evolution-family identity inside B4.
- #109: Four Diamond Mega Metagross ex for standard play and baseline set completion.
- #187: Full-art Mega Metagross ex for collectors who want the character-art upgrade.
- #200: Rainbow Mega Metagross ex for the highest-end Metagross chase.
Mega Gallade ex: the shorter premium route
Mega Gallade ex has a simpler known chase path. Its standard four-diamond Fighting-type Mega ex is the practical deck target, while #198 provides the rainbow Two Gold Star collection finish. Ralts #167 is worth marking alongside it for collectors aiming to assemble a visually matched Gallade family rather than treating #198 as an isolated hit.
The difference matters when choosing where to focus. Rayquaza has the broadest premium ladder, Metagross has both full-art and rainbow endpoints, and Gallade offers the most direct route from its standard Mega to a single marquee rainbow secret.

Choose a B4 target lane before opening deeply
The best target list depends on whether the goal is immediate deck access, a focused Mega collection, or a premium secret-rare display. Keeping those lanes separate prevents a common Pocket problem: owning attractive alternate art while missing the standard cards that make a new deck usable.
| Target lane | First cards to mark | Best endpoint | Why this route is efficient |
|---|---|---|---|
| Deck-first player | Mega Rayquaza ex #120, Mega Metagross ex #109, and the standard Mega Gallade ex | Core Mega cards plus their Evolution lines and compatible Trainers | Four-diamond versions deliver the cards needed to start building, while secret prints can wait. |
| Rayquaza-focused collector | Rayquaza #119, Mega Rayquaza ex #120, #188, and #203 | Mega Rayquaza ex #203 immersive | The line has the most visible progression from standard card to full art to immersive premium card. |
| Premium Mega collector | Mega Gallade ex #198, Hoopa ex #199, Mega Metagross ex #200, and Mega Rayquaza ex #203 | Rainbow and immersive secret-page completion | This route concentrates on the B4 cards with the strongest high-rarity visual treatments. |
Use the July update features to make pulls count
Ruler of the Skies arrived alongside several systems that change how efficiently B4 can be collected and tested. The new deck-sharing feature uses 2D QR codes, making it easier to pass a Mega shell between devices once the core cards are available. That is especially useful for comparing Mega Rayquaza ex, Mega Metagross ex, and Mega Gallade ex builds without manually recreating every list.
The new ◆◆◆◆-or-higher guaranteed booster category also deserves attention. Once its in-game conditions are met, the next booster from that same expansion is guaranteed to contain a four-diamond-or-higher card. This feature favors a deck-first approach because four-diamond Mega ex cards are the useful baseline targets before premium art variants enter the picture.
- Track standard Mega cards before secret gaps. Mark #109 and #120 immediately, then add the standard Mega Gallade ex to the same deck-focused list.
- Use the Card Dex as a numbered checklist. Separate #001–#155 from #156–#233 so normal completion and secret completion never blur together.
- Keep Rayquaza Mission progress active. Mega Rayquaza ex pulls can overlap with Secret Mission rewards, including Wonder Hourglasses and Shop Tickets.
- Prioritize time-limited mission windows. Elite Deck Gift Missions and Handy Card Collection Missions run from late July to late October, while the Summer Event Missions run in early August.
- Reserve the premium chase for a defined finish line. #198, #200, and #203 are stronger targets when the regular Mega cards are already covered.
Additional rollout events include the Ruler of the Skies Emblem Event and Community Week in early to mid August, followed by the Mega Houndoom ex Drop Event, Wonder Pick Event, and returning Deluxe Pack: ex Booster Packs in mid to late August. Returning players should also check Welcome Back Missions, which can award 120 Pack Hourglasses after the relevant inactivity requirement is met.
Three mistakes that waste B4 progress
- Reading 78 secret rares as a pack-rate promise: the 78-card figure measures unique secret slots in the set. Pull odds are a separate part of the booster system.
- Chasing #203 before obtaining #120: Mega Rayquaza ex’s immersive card is the prestige pull, while the four-diamond version is the dependable first target for a functional Mega Rayquaza plan.
- Ignoring the number break at #156: #156 is where the secret checklist starts. Keeping normal and secret totals separate makes Card Dex progress much easier to read.
- Treating every secret as a Mega card: B4’s premium pool also includes full-art Pokémon such as Wurmple, Lileep, Kricketune, Clefairy, and Ralts, plus rainbow ex cards such as Hoopa ex.
- Forgetting support cards: the expansion includes Trainers tied to Evolution Pokémon and Energy, so a Mega-focused deck plan should account for its support package rather than only the ex card itself.
The practical B4 collection plan
Start by treating Ruler of the Skies as two connected checklists: the 155-card standard set for playable foundations and the 78-card secret set for art, rarity, and completion goals. Mega Rayquaza ex #120 and Mega Metagross ex #109 are the strongest first marks for players. Mega Rayquaza ex #203, Mega Metagross ex #200, and Mega Gallade ex #198 are the clean premium targets once the deck-ready cards are secured.
That order gives every pull a job. Standard Megas move a deck forward, Secret Missions add resource value around the Rayquaza line, Card Dex updates keep multi-pack ownership accurate, and the secret section becomes a deliberate final chase instead of a 78-card distraction.
