Attack	Energy cost	Cards of Energy	Printed damage	Damage per Energy	Effect

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.

Acid1 Energy card

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.

How does Tentacool 56 compare with every other card?

What Tentacool 56 does without attacking

Tentacool 56 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.

Cowardice — Pokémon Power

At any time during your turn (before your attack), you may return Tentacool to your hand. (Discard all cards attached to Tentacool.) This power can't be used the turn you put Tentacool into play or if Tentacool is Asleep, Confused, or Paralyzed.

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.

Is Tentacool 56 efficient for the Energy it asks for?

Where this sits once the archive is cut by damage instead

What does being a Water card do for Tentacool 56?

What knocks out Tentacool 56 in one hit, and what does it knock out?

Of the 1,286 cards in the archive that can remove Tentacool 56 in a single attack, this one clears the bar by the smallest margin — 20 printed damage against a bar of 15.

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

Tentacool 56 is one print of Tentacool. 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.

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

16 prints carry this name in the archive. 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.

Tentacool 56 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, Acid, needs 1 Energy attached. Energy attaches once a turn, so that attack waits 1 turn from an empty card.
That works out at 10 damage for every Energy card attached.
Moving it out of the active spot costs no Energy at all.

Tentacool 56 — frequently asked questions

How much damage does it take to knock out Tentacool 56?

Tentacool 56 has 30 HP and a Lightning weakness at ×2, so a Lightning attack printed at 15 damage or more removes it in one turn. Any other type has to print the full 30.

What is the strongest attack on Tentacool 56?

Acid, printed at 10 damage for 1 Energy — 10 damage per Energy card.

What is the retreat cost of Tentacool 56?

None. Tentacool 56 carries a printed retreat cost of zero, so it can move out of the active spot without discarding any Energy. The once-a-turn limit on retreating still applies.

Can an older Tentacool print be played in a tournament?

Legality is read from the print, not from the Pokémon. Of the 16 prints listed on this page, 1 is 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 Tentacool 56 be played in a tournament?

It is legal in Unlimited play. Standard events run on a rotating list of sets, so check the current rotation before entering one.

Does this page say how good Tentacool 56 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.
