What each 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.

Orichalcum Fang 2 Energy50 damage for 2 Energy — 25 per Energy card50
Impact Blow 3 Energy200 damage for 3 Energy — 67 per Energy card200

Bars are printed damage against this card's own highest attack (200).

Why one of these damage figures carries a symbol

A number on a Pokémon card is not always the number that lands.

Orichalcum Fang is printed as 50+, 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 Koraidon ex 121 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.

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 200 is read as high or low rather than merely large.

Is Koraidon ex 121 strong for a Tera card?

Tera cards are built large to begin with, so measuring this one against the whole archive mixes up what the mechanic gives it with what the card itself gives it. Measured inside its own group, the two come apart.

What does being a Fighting card do for Koraidon ex 121?

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.

Koraidon ex 121 is one print of Koraidon. 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.

What has to be in play before Koraidon ex 121 can be?

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

Back to summary

Is this the strongest Koraidon print, and can the older ones still be played?

18 prints carry this name in the archive, and 16 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 (230 HP), and the highlighted row is the card this page is about.

Which rules apply to Koraidon ex 121, and where can it be played?

Two kinds of rule meet on one card — the sentence printed on the card face, and the rulebook clauses that apply because of what the card carries.

The rule printed on this card

“As long as this Pokémon is on your Bench, prevent all damage done to this Pokémon by attacks (both yours and your opponent’s). Pokémon ex rule: When your Pokémon ex is Knocked Out, your opponent takes 2 Prize cards.”

Prize cards your opponent takes when it is knocked out

Every knockout carries the opponent 2 steps closer to winning, and that is the cost of putting this card on the field whatever it cost to buy.

Koraidon ex 121 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, Impact Blow, needs 3 Energy attached. Energy attaches once a turn, so that attack waits 3 turns from an empty card.
That works out at 67 damage for every Energy card attached.
Moving it out of the active spot costs 2 more Energy, discarded from the card itself.

Where its HP stands, cut four ways

Every card in the archiveNo. 1,070 of 17,290

Fighting cardsNo. 105 of 1,884

ex cardsNo. 511 of 942

Ascended HeroesNo. 49 of 243

What actually removes it

A Psychic attack printed at 115 damage removes it in a single turn — that is the bar, not its 230 HP.
257 cards in the archive clear that bar.
Going the other way, it removes 3,471 cards in one attack.

Koraidon ex 121 — frequently asked questions

How much damage does it take to knock out Koraidon ex 121?

Koraidon ex 121 has 230 HP and a Psychic weakness at ×2, so a Psychic attack printed at 115 damage or more removes it in one turn. Any other type has to print the full 230.

What is the strongest attack on Koraidon ex 121?

Impact Blow, printed at 200 damage for 3 Energy — 67 damage per Energy card. During your next turn, this Pokémon can't use Impact Blow.

What is the retreat cost of Koraidon ex 121?

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

What does the + after the damage on Orichalcum Fang mean?

It marks the damage as conditional: the printed figure is the least it can deal, and the sentence on the card says what is added to it. The full sentence is printed on the card and quoted in the attack table on this page — "If any of your Pokémon were Knocked Out by damage from an attack during your opponent's last turn, this attack does 120 more damage."

Can an older Koraidon print be played in a tournament?

Legality is read from the print, not from the Pokémon. Of the 16 prints listed on this page, 15 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.

Can Koraidon ex 121 be played in a tournament?

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

What does the rule on Koraidon ex 121 mean?

The card reads “As long as this Pokémon is on your Bench, prevent all damage done to this Pokémon by attacks (both yours and your opponent’s). Pokémon ex rule: When your Pokémon ex is Knocked Out, your opponent takes 2 Prize cards.” That sentence is printed on the card itself, so it applies wherever the card is played.

Does this page say how good Koraidon ex 121 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.
