Reading Rainbow Cave's stat block

Stadium

Rainbow Cave is a Uncommon card from the Ruler of the Skies set — a Trainer card of the Stadium kind: no HP, no evolution, no attacks of its own. It hits the table, fires its effect, and steps aside.

What it does: Rainbow Cave Trainer - Stadium

Trainer cards are balanced by how often you may play them in a turn, not by damage. Read the effect against what your deck is short of — energy acceleration, draw, healing, or forcing a switch — because a Trainer is only strong when it solves the exact bottleneck your deck actually has.

Which pack actually drops it

Ruler of the Skies

The per-slot rate table doesn't yet cover Rainbow Cave's exact rarity grade, so no number is shown here — that's a data gap, not proof this is a PROMO card: Rainbow Cave genuinely belongs to Ruler of the Skies. Use Pack Points or trading below while this gets filled in. This page shows no per-slot odds or expected pack count for Rainbow Cave because the rate table doesn't yet cover its exact grade — making up a number here would be a lie. This is NOT a PROMO card: it belongs to Ruler of the Skies. Pack Points and trading below still work.

Three ways to own it

Which pack does this card drop from? Buy it with Pack Points Trade for it

For Rainbow Cave, pulling packs is still a real path — it belongs to Ruler of the Skies — but the per-slot rate table doesn't yet cover its exact grade, so this page won't guess a number. The second path removes luck entirely. Every pack you open awards 5 Pack Points (an official in-game mechanic, not part of the drop-rate table) regardless of what comes out of it, and those points accumulate until you can redeem this exact card outright. Rainbow Cave costs 70 PP — no pulls, no gambling, just the count. The third path is trading, which spends Shinedust rather than Pack Points, and whether it is open to you depends entirely on the card's rarity. For Rainbow Cave: It can be traded, and it costs 0 Shinedust.

Evolution line and other printings

Rainbow Cave does not evolve from or into anything — it stands alone. Some Pokémon are also printed more than once — across different sets or promo drops, with different art, different rarity, and sometimes different attacks under the same name. Where other printings of this card exist, they are linked on this page, because the stats can differ even when the name matches.

Where this card stands on the ladder

Rainbow Cave is not a core card in any of the 50 meta decks currently tracked. It is a filler card: Pack Points cost only 70, so do not burn packs hunting it — open packs for the rare slots and this one arrives on its own. The meta deck table is recomputed from tournament data (play rate plus win/loss/tie record), not from anyone's opinion. A card missing from that table can still be beautiful and still be expensive to trade for, but it will not win games on its own — those are two different questions and this page answers them separately.

Frequently asked questions

 Which pack should I open to get Rainbow Cave?

Ruler of the Skies — the card genuinely belongs to that pack. The page just hasn't computed an exact percentage yet because the per-slot data doesn't cover this grade.

 Roughly how many packs does it take to pull Rainbow Cave?

No reliable number here: the per-slot rate data doesn't yet cover Rainbow Cave's grade, even though it does drop from Ruler of the Skies. Use Pack Points or trading while this gets filled in.

 Can I trade for Rainbow Cave instead of pulling it?

It can be traded, and it costs 0 Shinedust. Trading uses Shinedust, and whether a card is tradeable at all is fixed by its rarity tier — Immersive Rare and Crown Rare cards can never be traded under any circumstance, so for those two tiers Pack Points or a direct pull are the only ways in.
