Pokémon Trading Card Game Pocket: Ruler of the Skies B4 Pull Odds Guide
Target Mega Rayquaza ex before spending heavily on B4’s secret layer. Mega Metagross ex, Mega Gallade ex, and the Evolution- or Energy-focused Trainer cards needed for a deck are the next efficient targets. The 78 secret cards belong at the end of the plan, where individual pulls become far less predictable and premium variants provide little immediate deck value.
Critical limitation: the published slot rates describe the chance of a rarity tier appearing in a pack position. They do not provide a precise per-pack probability for one named card such as Mega Rayquaza ex. A card’s exact odds depend on how many cards share its rarity tier and how the expansion’s individual card pool is distributed.
Ruler of the Skies B4 Set Size: 233 Cards, Including 78 Secrets
Ruler of the Skies is a 233-card Pokémon Trading Card Game Pocket expansion built around Mega Evolution cards and Dragon-focused lines. Its current checklist divides into 155 normal cards and 78 secret cards. Mega Rayquaza ex is the set’s headline pull, with Mega Metagross ex and Mega Gallade ex also positioned among its major Mega targets.
For collection planning, treat B4 as three separate projects rather than one uninterrupted chase. The 155-card normal pool is the practical completion target. The 78-card secret pool is the premium collection target. A Crown Rare, if B4 includes one, is a long-tail prestige pull and should not determine an efficient opening plan.
- Base completion: Collect the 155 normal cards, including the playable Pokémon and Trainer core.
- Full-set completion: Add the 78 secret cards after the normal pool is substantially complete.
- Premium completion: Pursue Crown-tier cards only as an optional final objective.
The 233-card total is the working B4 checklist. Card databases can receive catalogue updates while an expansion is being indexed, so use the Card Dex total in-game before committing resources solely to close the final missing card.
How Normal B4 Pack Slots Affect Your Pull Odds
Normal packs are five-card packs, but the five positions do not carry equal rarity weight. Cards one through three are primarily occupied by lower-rarity pulls. Card four is the first meaningful premium slot. Card five carries the strongest normal-pack chance of a Star, three-Star, or Crown Rare.
| Pack position | Role in a normal pack | What it means for B4 chasing |
|---|---|---|
| Cards 1-3 | Mostly lower-rarity cards | Useful for filling the normal checklist; poor positions for premium chase expectations. |
| Card 4 | First slot with meaningful higher-rarity access | Can produce premium tiers, though at substantially lower rates than card five. |
| Card 5 | Primary premium-rarity slot | Provides the best normal-pack chance for secret-style and Crown-tier outcomes. |
The difference between cards four and five is large enough to shape expectations. A premium pull in the fifth position is a normal outcome of the pack system; a premium pull in the fourth position is a much less frequent bonus.
Normal Pack Rarity Rates by Card Slot
| Rarity tier | Card 4 chance | Card 5 chance | Fifth-slot advantage |
|---|---|---|---|
| 1 Star | 2.572% | 10.288% | Four times the card-four rate |
| 2 Stars | 0.500% | 2.000% | Four times the card-four rate |
| 3 Stars | 0.222% | 0.888% | Four times the card-four rate |
| Crown Rare | 0.040% | 0.160% | Four times the card-four rate |
These are tier odds, not card-specific odds. For example, the 10.288% fifth-slot figure for a one-Star card is the chance of receiving any one-Star card eligible for that position. It does not mean Mega Rayquaza ex has a 10.288% pull rate.
Rare Packs, often called god packs, remain the outlier. They occur at roughly 0.05% of opens, or around one in 2,000 packs, and contain high-rarity cards throughout. This is an average-rate reference rather than a guarantee that a Rare Pack will arrive within 2,000 openings.
The Best Ruler of the Skies Targets, in Order
The efficient B4 target order is based on use first and rarity second. Opening packs for a card that can complete a deck has a clearer return than opening indefinitely for a cosmetic secret variant. Once the playable core is complete, every additional pack has a larger chance of being a duplicate or an off-target premium pull.
| Priority | Target | Reason to target it | When to stop |
|---|---|---|---|
| 1 | Mega Rayquaza ex | B4’s headline Mega ex, combining collector interest with immediate relevance for players building around the expansion. | Stop direct chasing after obtaining the copy or copies required for the intended deck or collection goal. |
| 2 | Mega Metagross ex and Mega Gallade ex | These are the other major announced Mega targets and provide the strongest follow-up value after Mega Rayquaza ex. | Stop once the preferred Mega line is complete; do not require every Mega before establishing a usable deck. |
| 3 | Playable ex cards and essential Trainer cards | Evolution- and Energy-related Trainer cards can be more important to a functioning list than a premium illustration. | Stop when the deck’s Pokémon, Evolution support, and Energy plan are covered. |
| 4 | Secret rares of Pokémon already being played | Premium variants add collection value while retaining relevance to cards already in the active pool. | Set a fixed spending limit; each secret chase has lower practical value than the playable core. |
| 5 | Crown-tier cards, if present | Crown Rares are the deepest long-tail chase under normal-pack odds. | Treat as optional collection prestige rather than a required endpoint. |
Mega Rayquaza ex receives the first position because it is the expansion’s central card. Pulling it early changes the rest of the plan: subsequent B4 packs can focus on the supporting Mega ex cards, Trainer pieces, and normal-set gaps instead of repeating the most visible chase objective.
Use the ◆◆◆◆ or Higher Guarantee on the Correct Expansion
The July 29 update adds a booster category that guarantees a ◆◆◆◆ or higher card when its in-game conditions are met. The guarantee applies to the next booster opened from the same expansion. For a player focused on Ruler of the Skies, that makes B4 the correct pack to open once the guarantee is active.
- Check the Card Dex to identify whether the desired B4 target is ◆◆◆◆ or a higher premium rarity.
- Keep the guaranteed booster within Ruler of the Skies if Mega Rayquaza ex, Mega Metagross ex, Mega Gallade ex, or another B4 high-rarity card remains the goal.
- Expect a guaranteed rarity tier, not a guaranteed named card. The guarantee improves the floor of the pull; it does not select Mega Rayquaza ex specifically.
This system is strongest when the target list is narrow. Using a high-rarity guarantee before deciding which Mega ex or Trainer package is needed can produce a valuable card that does not advance the intended collection or deck.

Pack-Spending Plans for Different B4 Goals
| Collection goal | Recommended stopping point | What to avoid |
|---|---|---|
| Low-budget deck start | Secure one featured Mega ex or the core cards for a single deck direction, then preserve resources. | Opening extra packs for one-Star, two-Star, or Crown cosmetic variants. |
| Mid-budget collection | Target Mega Rayquaza ex, then add Mega Metagross ex or Mega Gallade ex and the necessary Trainer support. | Trying to complete all 78 secrets before the normal playable pool is stable. |
| Full normal-set completion | Fill the 155-card normal checklist first, using the Card Dex to identify actual gaps. | Assuming repeated normal-pack openings will efficiently close a specific final missing card. |
| Premium completion | Begin secret hunting only after the normal pool and preferred playable Mega ex cards are secured. | Treating a Rare Pack or Crown pull as something that can be scheduled around average odds. |
Returning players who qualify for Welcome Back Missions receive 120 pack hourglasses. That resource is useful for rebuilding a B4 opening reserve, but it should not change the chase order: playable Mega ex cards and necessary Trainer support still come before the secret pool.
Track B4 Progress With the Updated Card Dex
The same update improves Card Dex registration for cards that appear in multiple booster packs, including cards already obtained before the change. This reduces record-keeping friction when tracking normal-set progress across available packs. Deck sharing through 2D pattern QR codes also makes it easier to preserve a finished Mega build once its card requirements are complete.
Use the Card Dex as a stop-control tool. Once the normal cards needed for a deck are registered, inspect the remaining gaps. If the missing cards are exclusively secret variants or a potential Crown chase, the collection has moved from practical acquisition into low-probability premium hunting.
Common B4 Chasing Errors
- Reading rarity odds as individual-card odds: a one-Star or Crown percentage applies to the tier in that slot, not automatically to Mega Rayquaza ex.
- Expecting premium cards from the first three positions: cards four and five carry the meaningful high-rarity weighting in normal packs.
- Chasing all secrets before building a deck: the 78-card secret pool is the expensive part of B4 completion.
- Using the ◆◆◆◆ or higher guarantee in another expansion: the next guaranteed booster is tied to the expansion selected for that opening.
- Planning around a Rare Pack: a roughly one-in-2,000 average rate is too infrequent to function as a normal collection strategy.
Recommended B4 Endpoint
For efficient Ruler of the Skies progress, finish the playable normal pool, prioritize Mega Rayquaza ex, add Mega Metagross ex or Mega Gallade ex where needed, and reserve secret or Crown-tier chasing for a separate premium-completion budget. The 155 normal cards are the practical target; the remaining 78 secret cards are the long-tail project.
