Mewtwo-EX 158 is a Psychic Pokémon card with 170 HP, printed as Basic EX.

What each 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.

  • Shatter Shot 1 Energy30 damage for 1 Energy — 30 per Energy card30

Bars are printed damage against this card's own highest attack (30).

Why one of these damage figures carries a symbol

A number on a Pokémon card is not always the number that lands.

  • Shatter Shot is printed as 30×, so the printed number is multiplied — the attack deals that much for each thing the sentence beside it counts.

How does Mewtwo-EX 158 compare with every other card?

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.

Is Mewtwo-EX 158 efficient for the Energy it asks for?

Printed damage on its own says nothing — a 30 damage attack that needs 1 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 30 is read as high or low rather than merely large.

Back to summary

Is Mewtwo-EX 158 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 Psychic card do for Mewtwo-EX 158?

Of the 408 cards in the archive that can remove Mewtwo-EX 158 in a single attack, this one clears the bar by the smallest margin — 90 printed damage against a bar of 85.

Mewtwo-EX 158 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, Shatter Shot, needs 1 Energy attached. Energy attaches once a turn, so that attack waits 1 turn from an empty card.
  • That works out at 30 damage for every Energy card attached.
  • Moving it out of the active spot costs 2 more Energy, discarded from the card itself.

Mewtwo-EX 158 — frequently asked questions

How much damage does it take to knock out Mewtwo-EX 158?

Mewtwo-EX 158 has 170 HP and a Psychic weakness at ×2, so a Psychic attack printed at 85 damage or more removes it in one turn. Any other type has to print the full 170.

What is the strongest attack on Mewtwo-EX 158?

Shatter Shot, printed at 30 damage for 1 Energy — 30 damage per Energy card. This attack does 30 damage times the amount of Psychic Energy attached to this Pokémon.

What is the retreat cost of Mewtwo-EX 158?

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

What does the × after the damage on Shatter Shot mean?

It marks the damage as conditional: the printed figure is dealt once for each thing the sentence on the card counts. The full sentence is printed on the card and quoted in the attack table on this page — "This attack does 30 damage times the amount of Psychic Energy attached to this Pokémon."

Can Mewtwo-EX 158 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.

The card reads “Pokémon-EX rule: When a Pokémon-EX has been 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 Mewtwo-EX 158 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.
