What do the attacks on Holon's Electrode 21 cost, and what do they hit for?
The card prints 1 attack. The strongest asks for 2 Energy and returns 30 damage, which is 15 damage for every Energy card attached.
| Attack | Energy cost | Cards of Energy | Printed damage | Damage per Energy | Effect |
|---|---|---|---|---|---|
| Dazzle Blast | 1 Lightning + 1 Colorless | 2 | 30 | 15 | The Defending Pokémon is now Confused. |
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.

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.

Back to summaryIs Holon's Electrode 21 efficient for the Energy it asks for?
Printed damage on its own says nothing — a 30 damage attack that needs 2 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 2 typically return 32.5 damage per Energy card. This card returns 15.
| Group | Share | Value |
|---|---|---|
| 1 Energy | 49.0 | 49 damage typical |
| 2 Energy | 32.5 | 65 damage typical |
| 3 Energy | 34.7 | 104 damage typical |

| Holon's Electrode 21 — this card | 15.0 | 30 damage for 2 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 30 is read as high or low rather than merely large.
What does being a Lightning card do for Holon's Electrode 21?
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.

What being a Lightning card is worth
Groups that most often print a Lightning weakness: Water (2,435 cards). Against those, this card's printed damage counts double. Going the other way, Lightning cards are themselves most exposed to Fighting.
What knocks out Holon's Electrode 21 in one hit, and what does it knock out?
Weakness doubles the damage a Fighting attack deals to this card, so the bar it has to clear is 35 printed damage rather than 70.

Holon's Electrode 2170 HPWhy this card was picked to stand opposite
Of the 1,208 cards in the archive that can remove Holon's Electrode 21 in a single attack, this one clears the bar by the smallest margin — 40 printed damage against a bar of 35. 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 Holon's Electrode as a Pokémon, across every card it has been printed on?
Holon's Electrode 21 is one print of Holon's Electrode. 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 Holon's Electrode 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 can you use instead of Holon's Electrode 21?
Every card below asks a deck for the same kind of slot, so the comparison is between what they print, not what they cost.

Which rules apply to Holon's Electrode 21, 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
“You may attach this as an Energy card from your hand to 1 of your Pokémon that already has an Energy card attached to it. When you attach this card, return an Energy card attached to that Pokémon to your hand. While attached, this card is a Special Energy card and provides every type of Energy but 2 Energy at a time. (Has no effect other than providing Energy.)”
| Clause | What the rulebook says | Cards it applies to | Share of the archive |
|---|---|---|---|
| Weakness | Some Pokemon have Weakness or Resistance to Pokemon of certain types, marked in the lower-left corner of the card. | 16,744 cards | 81.9% |
| Retreat | Retreat your Active Pokemon (only once per turn). | 17,244 cards | 84.3% |
| Energy per turn | You can attach Energy just once each turn! | 17,180 cards | 84.0% |
Counted across 20,444 English cards. A clause applies to this card because the card carries the property the clause names, not because we judged it to.

Holon's Electrode 21 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, Dazzle Blast, needs 2 Energy attached. Energy attaches once a turn, so that attack waits 2 turns from an empty card.
- That works out at 15 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 — Holon's Voltorb has to be on the field first.
Where its HP stands, cut four ways
What actually removes it
- A Fighting attack printed at 35 damage removes it in a single turn — that is the bar, not its 70 HP.
- 1,221 cards in the archive clear that bar.
- Going the other way, it removes 626 cards in one attack.
