Character info
The character
Glass Trumpet is an Item card in the Pokémon Trading Card Game, part of the Trainer card category. It is not a character but an in-game tool designed to support strategies built around Tera Pokémon. Items like this represent equipment or resources that trainers use to assist their Pokémon in battle.
This card
This is the Secret Rare, full art printing of Glass Trumpet from the Ascended Heroes set, numbered 260 out of a base set of 217 cards. The artwork by Toyste Beach depicts a stylized glass trumpet amid streaks of blue light, with holographic foil finishing throughout the card border and image. The card carries the ASC set code and was released January 30, 2026.
How it plays
Glass Trumpet can only be used if the player has any Tera Pokémon in play. When played, it allows the player to choose up to 2 of their Benched Pokémon with a Tera star symbol and attach a Basic Energy card from their discard pile to each of them. The card also carries the standard Item reminder text that any number of Item cards may be played during a turn.

A catalogue match is not the authenticity check. It confirms the card is the card it claims to be. Whether it is genuine was checked separately, on the card itself; see Authenticity below.
Authenticity
WinnTCG authenticated this card in hand, on the bench, against genuine Pokémon cards. It was checked four ways: light shone through it to check the core, its weight on a scale, its thickness measured, and its print pattern and surface texture under magnification.
How this card was graded
WinnTCG graded this card in hand, on the bench. The card was in our hands, and we sealed the case ourselves. We photographed it here under controlled light to show which card is in the case and where anything we marked sits on it.
If you are buying this slab: the grade is WinnTCG’s judgement of the card that was in front of us, and WinnTCG sealed this case. The photographs above are of that card. Compare them against what you can see through the case, because a case can be opened by anyone who has held it since.
The working behind this grade
Every grade here is published with its reasoning. The report states what each measurement returned, what the model proposed on each axis, where the grader disagreed with it, and every defect marked on the photographs above.
