ACE SPEC Cards
An ACE SPEC is a Trainer or Special Energy card that is stronger than usual, and a deck can hold only one of them in total. Here is how the limit works, which ACE SPEC cards are legal in Standard, and where they came from.
The short answer
ACE SPEC is a label printed on some Trainer and Special Energy cards. Each one does something a normal card of its kind cannot, and each carries the same restriction: "You can't have more than 1 ACE SPEC card in your deck." That is one ACE SPEC across the whole deck, not one of each name. You can identify one by the ACE SPEC banner on the card and by its rarity, ACE SPEC Rare in the current sets.
The one-per-deck rule
The limit is on the category, so a deck that plays Prime Catcher cannot also play Master Ball, Secret Box or any other ACE SPEC. It also overrides the usual four-copy rule: you cannot run two copies of the same ACE SPEC either.
ACE SPEC cards are otherwise ordinary. An ACE SPEC Item is still an Item, so you can play it alongside other Items in the same turn, and an ACE SPEC Pokémon Tool still takes the one Tool slot on a Pokémon. The TurnZero HQ deck builder counts ACE SPEC cards across the whole list and flags a second one. Every deck building rule →
ACE SPEC cards in Standard
Every ACE SPEC printed since 2024 carries regulation mark H, which is legal in Standard alongside I and J since the rotation on April 10, 2026. As of October 2026, the newest ACE SPEC cards in TurnZero HQ's catalog are from Prismatic Evolutions (January 2025); the Mega Evolution sets have added none. Several were printed twice, and a reprint counts as the same card.
Standard rotates once a year, and the H mark is the oldest one legal now, so it is the next to leave. Check The Pokémon Company International's rotation announcement before you build for an event. How format legality works →
Where ACE SPEC came from
ACE SPEC began in Black & White: Boundaries Crossed in November 2012, and 13 were printed across four sets before the label went away after Plasma Blast in August 2013. Those cards have no regulation mark, so they are legal in Expanded, which reaches back to the Black & White series, and not in Standard.
Some of the old names returned. Master Ball, Scoop Up Cyclone and Scramble Switch were each printed again in Scarlet & Violet. Others stayed in Expanded only, such as Computer Search, which has you discard 2 cards to search your deck for any card.
Choosing your one ACE SPEC
Since a deck gets one, the choice comes down to the deck's weakest point. Prime Catcher suits a deck that needs to Knock Out a specific Benched Pokémon, because it brings that Pokémon up and swaps your own Active in the same card. Master Ball finds a missing piece of an evolution line. Unfair Stamp shuffles both hands away after one of your Pokémon is Knocked Out, then you draw 5 cards and your opponent draws 2, which helps a deck that is behind.
Neo Upper Energy shows the other kind: a Special Energy that provides every type of Energy, 2 at a time, while attached to a Stage 2 Pokémon. It fits a deck built around Stage 2 attackers with mixed Energy costs and does little anywhere else, which is the tradeoff with most ACE SPEC cards. The decks leading Standard →
Frequently Asked Questions
What is an ACE SPEC card in Pokémon?
An ACE SPEC is a Trainer or Special Energy card stronger than a normal card of its kind, with one restriction printed on it: you can't have more than 1 ACE SPEC card in your deck. The limit counts every ACE SPEC together, so a deck with Prime Catcher cannot also play Master Ball.
How many ACE SPEC cards can you have in a Pokémon deck?
One, in total. It is not one of each name. A deck may hold a single ACE SPEC card of any kind, or none.
Are ACE SPEC cards legal in Standard?
The Scarlet & Violet ACE SPEC cards carry regulation mark H, which is legal in Standard since April 10, 2026, together with I and J. The original ACE SPEC cards from 2012 and 2013 have no regulation mark and are legal only in Expanded, unless the same card has a Standard-legal reprint.
When did ACE SPEC cards come out?
ACE SPEC first appeared in Black & White: Boundaries Crossed in November 2012 and ran through Plasma Blast in August 2013. It returned in Scarlet & Violet: Temporal Forces in March 2024.
Can a Pokémon be an ACE SPEC?
Not in English sets so far. Every ACE SPEC in TurnZero HQ's catalog is an Item, a Pokémon Tool, a Stadium or a Special Energy card.
