What Mewtwo SM77 does without attacking

Mewtwo SM77 carries 1 printed effect that work outside the attack step, so it can matter on a turn the card never attacks.

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

Pressure — Ability

As long as this Pokémon is your Active Pokémon, your opponent's Active Pokémon's attack do 20 less damage (before applying Weakness and Resistance).

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 Mewtwo SM77 efficient for the Energy it asks for?

Printed damage on its own says nothing — a 100 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.

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

18 of the 87 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.

Every card below carries the same Pokédex number as this one, so they are the same Pokémon printed as different cards — different stages, different mechanics and different names all sit in this group.

Which rules apply to Mewtwo SM77, 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.

Rulebook clauses that apply to Mewtwo SM77
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.

Mewtwo SM77 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, Super Psy Bolt, needs 3 Energy attached. Energy attaches once a turn, so that attack waits 3 turns from an empty card.
That works out at 33 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. 4,897 of 17,290

Psychic cardsNo. 576 of 2,334

SM Black Star PromosNo. 127 of 247

What actually removes it

A Psychic attack printed at 60 damage removes it in a single turn — that is the bar, not its 120 HP.
720 cards in the archive clear that bar.
Going the other way, it removes 1,694 cards in one attack.

Mewtwo SM77 — frequently asked questions

How much damage does it take to knock out Mewtwo SM77?

Mewtwo SM77 has 120 HP and a Psychic weakness at ×2, so a Psychic attack printed at 60 damage or more removes it in one turn. Any other type has to print the full 120.

What is the strongest attack on Mewtwo SM77?

Super Psy Bolt, printed at 100 damage for 3 Energy — 33 damage per Energy card.

What is the retreat cost of Mewtwo SM77?

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

Can an older Mewtwo print be played in a tournament?

Legality is read from the print, not from the Pokémon. Of the 87 prints listed on this page, 18 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 Mewtwo SM77 be played in a tournament?

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

Does this page say how good Mewtwo SM77 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.
