Back to summaryWhat Sunny Castform 31 does without attacking
Sunny Castform 31 carries 1 printed effect that work outside the attack step, so it can matter on a turn the card never attacks.
Why this sits apart from the attacks
An attack costs Energy and ends your turn. What is printed above does neither — it is available while the card is in play, so it is a different kind of cost to a deck. Attack costs are in the section above.
Temperamental Weather can only be used once a turn
The words once during your turn are printed in it, which caps it at one use per turn on that one card. Two copies of the card in play are two separate Pokémon, so each carries its own use.
What does being a Fire card do for Sunny Castform 31?
Type decides two things at once — which cards take double damage from this one, and which cards deal double to it. Both are read from the weakness printed on each group, not from a rule of thumb.
17,249 cards carry an energy type. The note under each name is the weakness printed most often on that group.
| Group | Share | Value |
|---|---|---|

What being a Fire card is worth
Groups that most often print a Fire weakness: Grass (2,387 cards) and Metal (925 cards). Against those, this card's printed damage counts double. Going the other way, Fire cards are themselves most exposed to Water.
What knocks out Sunny Castform 31 in one hit, and what does it knock out?
Weakness doubles the damage a Water attack deals to this card, so the bar it has to clear is 35 printed damage rather than 70.

Sunny Castform 3170 HPWhy this card was picked to stand opposite
Of the 1,263 cards in the archive that can remove Sunny Castform 31 in a single attack, this one clears the bar by the smallest margin — 40 printed damage against a bar of 35. Anything printed higher removes it just as surely, so this is where the line actually sits, and this print is legal in Standard play today.

| Palafin ex (193) | Twilight Masquerade | 340 | 250 | 500 |
70 HP against a Water ×2 weakness means any Water attack printed at 35 damage or more is enough. 1,277 cards in the archive clear that bar.
Back to summaryWhat is Sunny Castform as a Pokémon, across every card it has been printed on?
Sunny Castform 31 is one print of Sunny Castform. The figures below are about the Pokémon rather than this single card — how many times it has been printed, how tough those prints run, and how many of them can still be played.
Is this the strongest Sunny Castform print, and can the older ones still be played?
2 prints carry this name in the archive. They share a Pokémon but not a card — printed HP, printed damage and tournament legality all move from one print to the next.
Bar height and the number above each bar = highest HP that year; the two digits below = the year.
| Set | Regulation mark | Standard | |
|---|---|---|---|
| Sunny Castform 26/101 | EX Hidden Legends | No mark printed | Not legal in Standard |
| Sunny Castform 31/113 | EX Delta Species | No mark printed | Not legal in Standard |
0 of the 2 prints listed here are legal in Standard play. An older print of the same Pokémon is a different card for legality, because legality is read from the print rather than from the name — so owning the cheap old copy does not always mean you can enter with it.
Back to summaryWhich other cards share the Pokémon behind Sunny Castform 31?
