What Decidueye ex 12 does without attacking

Decidueye ex 12 carries 1 printed effect that work outside the attack step, so it can matter on a turn the card never attacks.

Printed effects

Capped at once a turn

None

Read from the printed text quoted below, not counted anywhere else.

Sniper's Eye — Ability

If your opponent has exactly 4 cards in their hand, ignore all Colorless Energy in the costs of attacks used by this Pokémon.

Quoted from the card face. The label after the dash is how the card itself names the effect.

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.

Back to summary

Is Decidueye ex 12 efficient for the Energy it asks for?

Printed damage on its own says nothing — a 240 damage attack that needs 4 Energy and one that needs two are different cards. Dividing one by the other puts every attack on the same scale.

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

Back to summary

Is Decidueye ex 12 strong for a ex card?

ex 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 Grass card do for Decidueye ex 12?

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.

Of the 187 cards in the archive that can remove Decidueye ex 12 in a single attack, this one clears the bar by the smallest margin — 160 printed damage against a bar of 160.

This card cannot be played from your hand onto an empty spot — it goes on top of Dartrix.
The line runs 4 stages, so the first card has to be in play 3 turns before this one can be.

Bars are the highest HP ever printed on that stage, measured against the top of this line (320 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 Decidueye print, and can the older ones still be played?

26 prints carry this name in the archive, and 18 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 (320 HP), and the highlighted row is the card this page is about.

18 rows are shown of the 26 prints counted under this name.

The rule printed on this card

“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.

Decidueye ex 12 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, Crushing Arrow, needs 4 Energy attached. Energy attaches once a turn, so that attack waits 4 turns from an empty card.
That works out at 60 damage for every Energy card attached.
Moving it out of the active spot costs 2 more Energy, discarded from the card itself.
It cannot start the game in play — Dartrix has to be on the field first.

Where its HP stands, cut four ways

Every card in the archiveNo. 207 of 17,290

Grass cardsNo. 22 of 2,387

ex cardsNo. 145 of 942

Perfect OrderNo. 4 of 93

What actually removes it

A Fire attack printed at 160 damage removes it in a single turn — that is the bar, not its 320 HP.
187 cards in the archive clear that bar.
Going the other way, it removes 1,943 cards in one attack.

Decidueye ex 12 — frequently asked questions

How much damage does it take to knock out Decidueye ex 12?

Decidueye ex 12 has 320 HP and a Fire weakness at ×2, so a Fire attack printed at 160 damage or more removes it in one turn. Any other type has to print the full 320.

What is the strongest attack on Decidueye ex 12?

Crushing Arrow, printed at 240 damage for 4 Energy — 60 damage per Energy card. Discard an Energy from your opponent's Active Pokémon.

What is the retreat cost of Decidueye ex 12?

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

Can an older Decidueye print be played in a tournament?

Legality is read from the print, not from the Pokémon. Of the 18 prints listed on this page, 8 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.

What does Decidueye ex evolve from?

Dartrix. It cannot be played straight from your hand onto an empty spot — the earlier stage has to be in play first.

Can Decidueye ex 12 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 Decidueye ex 12 mean?

The card reads “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 Decidueye ex 12 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.
