Reading Gastrodon's stat block

Gastrodon is a Art Rare Stage 1 card from the Space-Time Smackdown set with 120 HP. Every STAT on this page comes straight from the card record; the expected pack count further down is a statistical estimate recomputed from the pull table, not a promise.

Its weakness is Lightning, which is the fastest way for an opponent to remove it in a straight trade, and its retreat cost is 3 — that is what you pay in energy to swap it out mid-turn, and it is the number people forget until the card is stranded in the active spot.

Its attacks:

  • Muddy Water — 60 damage · cost Water + Colorless + Colorless — This attack also does 20 damage to 1 of your opponent's Benched Pokémon.

Read the energy costs together, not just the damage. A card with two attacks usually trades a cheap, weak opener for a pricier attack that does the real work, and the question that decides whether it belongs in a deck is whether you can actually pay for the big one on curve.

Which pack actually drops it

Rare cards are not spread evenly across a set. Each one is locked to specific packs, and opening the wrong pack from the right set means this card never shows up no matter how many you buy. Gastrodon drops from Palkia.

Odds are set per slot, not per card — and the slot layout differs from one pack type to another, so never carry one pack's formula over to another. The Palkia pack gives 5 cards per opening — slot 1 is always Common · slot 2 is always Common · slot 3 is always Common · slot 4: 90.00% is Uncommon · slot 5: 60.00% is Uncommon. For Gastrodon that works out to 0.21% in slot 4 · 0.86% in slot 5, which is 1.08% for any single pack, or about 93 packs before you can expect to see one.

Three ways to own it

Pulling is only the first path, and it is the one that can betray you: 1.08% per pack means the expected 93 packs is an average, not a promise.

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. Gastrodon costs 400 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 Gastrodon: It can be traded for 4,000 Shinedust.

Evolution line and other printings

Gastrodon evolves from Shellos. The full line is: Shellos → Gastrodon.

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

Gastrodon is not a core card in any of the 50 meta decks currently tracked. Chase it for the art and the collection, not for the ladder — spend Pack Points on core cards first, then come back for this one.

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 Gastrodon?

Gastrodon drops from Palkia. Opening a different pack from the same set will not produce it, because pack variants inside one set carry completely different rare-card pools.

Roughly how many packs does it take to pull Gastrodon?

About 93 packs on average. That comes from the per-slot pull table rather than a single blended number: 0.21% in slot 4 · 0.86% in slot 5, which is 1.08% for any one pack. It is an expected value — a statistical estimate, not a guarantee: half of all players will need more.

Can I trade for Gastrodon instead of pulling it?

It can be traded for 4,000 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.
