Is Onix 138 efficient for the Energy it asks for?

What does being a Fighting card do for Onix 138?

Of the 681 cards in the archive that can remove Onix 138 in a single attack, this one clears the bar by the smallest margin — 60 printed damage against a bar of 55. 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.

What is Onix as a Pokémon, across every card it has been printed on?

Onix 138 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.

Onix has been printed 33 times, and the printed numbers move from one print to the next. Point at a card to see it full size.Tap a card to open its page.

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.

What has to be in play before Onix 138 can be?

Onix evolves from an earlier stage, so the whole line has to be built before this card reaches the field.

It is not the end of the line either — Steelix evolves from this card, so a deck can keep going past it.
The line runs 2 stages, so the first card has to be in play 1 turn before this one can be.
Every print in the line shares Pokédex number 095.

Bars are the highest HP ever printed on that stage, measured against the top of this line (200 HP). The note beside each bar is the hardest attack printed at that stage.

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.

Rows run from the toughest print down. Bars are printed HP, measured against the toughest print of this name shown here (200 HP), and the highlighted row is the card this page is about.

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.

8,194 cards in the archive carry a regulation mark. Older prints carry none at all, so this is not the whole archive.

The regulation mark is the single letter recorded with each modern card. Older prints carry no mark at all, so this axis covers only the part of the archive that has one.

Onix 138 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, Rock Throw, needs 3 Energy attached. Energy attaches once a turn, so that attack waits 3 turns from an empty card.
That works out at 30 damage for every Energy card attached.
Moving it out of the active spot costs 4 more Energy, discarded from the card itself.

Where its HP stands, cut four ways

Every card in the archiveNo. 5,859 of 17,290

Fighting cardsNo. 676 of 1,884

Fusion StrikeNo. 109 of 245

What actually removes it

A Grass attack printed at 55 damage removes it in a single turn — that is the bar, not its 110 HP.
681 cards in the archive clear that bar.
Going the other way, it removes 2,989 cards in one attack.

Onix 138 — frequently asked questions

How much damage does it take to knock out Onix 138?

Onix 138 has 110 HP and a Grass weakness at ×2, so a Grass attack printed at 55 damage or more removes it in one turn. Any other type has to print the full 110.

What is the retreat cost of Onix 138?

4 Energy, discarded from this card to move it out of the active spot. Retreating is allowed once per turn.

Can an older Onix print be played in a tournament?

Legality is read from the print, not from the Pokémon. Of the 30 prints listed on this page, 4 are legal in Standard play. The rest can still be played in formats that accept them, and the table on this page names the regulation mark each print carries.

It is legal in Unlimited and Expanded play, and it carries regulation mark E. Standard events run on a rotating list of sets, so check the current rotation before entering one.

Does this page say how good Onix 138 is in a deck?

No. Every figure here is read from the printed card. Deck lists, tournament results and win rates are not published on this site, because the card files it reads do not contain them.
