What do the attacks on Onix 57 cost, and what do they hit for?
The card prints 1 attack. The strongest asks for 3 Energy and returns 20 damage, which is 7 damage for every Energy card attached.
| Attack | Energy cost | Cards of Energy | Printed damage | Damage per Energy | Effect |
|---|---|---|---|---|---|
| Swing Around | 3 Colorless | 3 | 20+ | 7 | Flip 2 coins. This attack does 20 damage plus 20 more damage for each heads. |
Retreating costs a further 3 Energy, discarded from this card, and that cost is paid on top of anything in the table.
The Energy this attack asks a deck to attach before it can be used, drawn as the symbols printed on the card.
One Energy card attaches per turn, so the number of symbols is also the number of turns the attack waits.
Why one of these damage figures carries a symbol
A number on a Pokémon card is not always the number that lands.
- Swing Around is printed as 20+, so the printed number is a floor — the attack deals at least that much, and the sentence beside it says what adds to it.
How does Onix 57 compare with every other card?
Each bar below is the whole archive cut by one printed figure, with the band this card falls into marked. A number on its own says nothing about whether it is high or low — the shape of the archive does.

The ceiling of this archive is Mega Emboar ex at 380 HP — every bar here is measured against it.
This card prints 90 HP, which is 24% of that ceiling.
Every figure in this panel is counted the same way: from the card files this site reads, read July 28, 2026, over the 17,290 cards that print an HP figure. Each bar is measured against the tallest HP in the archive, 380 HP.

Back to summaryIs Onix 57 efficient for the Energy it asks for?
Printed damage on its own says nothing — a 20 damage attack that needs 3 Energy and one that needs two are different cards. Dividing one by the other puts every attack on the same scale.
Each bar is what cards asking that much Energy typically print, divided by the Energy they ask for. The number beside the bar is that figure.
Cards whose cheapest attack costs 3 typically return 34.7 damage per Energy card. This card returns 7.
| Group | Share | Value |
|---|---|---|
| 1 Energy | 49.0 | 49 damage typical |
| 2 Energy | 32.5 | 65 damage typical |
| 3 Energy | 34.7 | 104 damage typical |
| 4 Energy | 27.8 | 111 damage typical |
| 5 Energy | 41.8 | 209 damage typical |
| Onix 57 — this card | 7.0 | 20 damage for 3 Energy |
Further right is a costlier attack, further up is a harder-hitting one, so the cheap and heavy corner is top left. The size of a grey dot is how many cards sit at that Energy cost.

Where this sits once the archive is cut by damage instead
The bars above cut the archive by what an attack asks for. Cut the same archive by what an attack prints and the groups come out differently — the damage ranges on record are gathered on one page, which is where a figure like 20 is read as high or low rather than merely large.
What does being a Fighting card do for Onix 57?
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.

|---|---|---|
| Psychic | 13.5% | 2,335 cards |

Read from the weakness printed on each group. The first row is this card; the rest are groups that most often print a Fighting weakness.
What being a Fighting card is worth
Groups that most often print a Fighting weakness: Colorless (2,173 cards), Lightning (1,520 cards) and Darkness (1,249 cards). Against those, this card's printed damage counts double. Going the other way, Fighting cards are themselves most exposed to Grass.
What knocks out Onix 57 in one hit, and what does it knock out?
Weakness doubles the damage a Grass attack deals to this card, so the bar it has to clear is 45 printed damage rather than 90.
50 damage becomes 100 against this card
Onix 5790 HPWhy this card was picked to stand opposite
Of the 875 cards in the archive that can remove Onix 57 in a single attack, this one clears the bar by the smallest margin — 50 printed damage against a bar of 45. 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.

90 HP against a Grass ×2 weakness means any Grass attack printed at 45 damage or more is enough. 880 cards in the archive clear that bar.

What is Onix as a Pokémon, across every card it has been printed on?
Onix 57 is one print of Onix. 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.
Every Onix print on record, split by whether it can still be entered in Standard play.
Legality is read from the print rather than from the Pokémon, so an older copy of the same Pokémon is a different card for tournament purposes.
Back to summaryWhat has to be in play before Onix 57 can be?
Onix evolves from an earlier stage, so the whole line has to be built before this card reaches the field.
Every print of a stage is counted, not just the one shown in the chain above, so the bar is the ceiling that stage has reached rather than one card from it.
Is this the strongest Onix print, and can the older ones still be played?
33 prints carry this name in the archive, and 30 of them are laid out below. 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.
30 rows are shown of the 33 prints counted under this name.

4 of the 30 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.

Onix 57 in depth — what these figures add up to
Three readings of the same card, side by side: what it costs to get going, where it sits among the cards it will be compared with, and what takes it off the field.
What it asks a deck for
- Its hardest attack, Swing Around, needs 3 Energy attached. Energy attaches once a turn, so that attack waits 3 turns from an empty card.
- That works out at 7 damage for every Energy card attached.
- Moving it out of the active spot costs 3 more Energy, discarded from the card itself.
Where its HP stands, cut four ways
What actually removes it
- A Grass attack printed at 45 damage removes it in a single turn — that is the bar, not its 90 HP.
- 880 cards in the archive clear that bar.
- Going the other way, it removes 167 cards in one attack.
