What do the attacks on Yveltal BREAK 66 cost, and what do they hit for?
The card prints 1 attack. The strongest asks for 3 Energy and returns 120 damage, which is 40 damage for every Energy card attached.
| Attack | Energy cost | Cards of Energy | Printed damage | Damage per Energy | Effect |
|---|---|---|---|---|---|
| Baleful Night | 3 Darkness | 3 | 120 | 40 | This attack does 30 damage to each of your opponent's Benched Pokémon that has any damage counters on it. (Don't apply Weakness and Resistance for Benched Pokémon.) |
This card has no retreat cost at all, so it can leave the active spot without discarding any Energy — the only limit is that retreating happens once a turn.
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.

Back to summaryIs Yveltal BREAK 66 efficient for the Energy it asks for?
Printed damage on its own says nothing — a 120 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 40.
| 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 |
| Yveltal BREAK 66 — this card | 40.0 | 120 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 120 is read as high or low rather than merely large.
What does being a Darkness card do for Yveltal BREAK 66?
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 |
|---|---|---|
| Psychic | 13.5% | 2,335 cards |
| Water | 14.1% | 2,435 cards |
| Colorless | 12.6% | 2,173 cards |
| Fire | 9.1% | 1,574 cards |

What being a Darkness card is worth
No group in the archive most often prints a Darkness weakness, so this type gains nothing automatic from the weakness rule.
What is Yveltal BREAK as a Pokémon, across every card it has been printed on?
Yveltal BREAK 66 is one print of Yveltal BREAK. 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 Yveltal BREAK 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 Yveltal BREAK 66 can be?
Yveltal BREAK evolves from Yveltal, so the whole line has to be built before this card reaches the field.
- This card cannot be played from your hand onto an empty spot — it goes on top of Yveltal.
- 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 717.
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 Yveltal BREAK print, and can the older ones still be played?
28 prints carry this name in the archive, and 26 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.
26 rows are shown of the 28 prints counted under this name.

4 of the 26 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.

Yveltal BREAK 66 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, Baleful Night, needs 3 Energy attached. Energy attaches once a turn, so that attack waits 3 turns from an empty card.
- That works out at 40 damage for every Energy card attached.
- Moving it out of the active spot costs no Energy at all.
- It cannot start the game in play — Yveltal has to be on the field first.
