Teal Mask Ogerpon ex (TWM 25). Gengar & Mimikyu-GX (TEU 165). Subject: Request for Investigation: Horror House-GX Restriction May Not Be Properly Applied to Abilities Hello TCG ONE team, I would like to request an investigation into a potentially broader implementation issue involving Horror House-GX. During a game in which the effect of Horror House-GX was active, my opponent was able to use Teal Mask Ogerpon ex’s Teal Dance Ability to attach a Basic Grass Energy card from their hand to itself. This interaction raises concerns that the restriction imposed by Horror House-GX may not be correctly enforced when an opponent uses an Ability that involves playing or attaching a card from their hand. Rather than being limited to this specific card interaction, I would appreciate it if you could investigate whether the game engine correctly applies the Horror House-GX restriction to all relevant Abilities that allow cards to be played or attached from the hand. In particular, could you please verify whether this is an isolated interaction issue or a more general bug affecting the implementation of Horror House-GX? I can provide the game log and additional details to help reproduce the issue. Thank you for your time and for maintaining TCG ONE. ------------------Begin Game Log------------------ **The game is about to start** Type: QuickPlay Format: Unlimited Battle begins between Solas\_Ray555 and Monke\_God!

Triage Agent: Valid, and already fixed. Same cause as [Possible TCG ONE Bug — Ditto Prism Star Evolves During Horror House-GX](https://forum.tcgone.net/t/17567). Teal Dance attaches a card from your hand, and Horror House GX forbids that (TPCi Rules Team 2021-07-01; the official Japanese Q&A refuses Cherrim’s Spring Bloom, Frosmoth’s Ice Dance and Haxorus’s Grind Up the same way). Your game on 2026-10-29 ran the engine deployed on 2026-10-27, which didn’t have the fix yet; it went live on 2026-10-30 (commit 9b0affbbc), and a test now covers Teal Dance. On the general question: Horror House GX now also stops Abilities and attacks that attach or bench a card from the hand without marking it as played from the hand (Haxorus UNM 156, Greninja-GX SM197). That fix goes live with the next engine update. ---

I have one question regarding Horror House GX. Is there a possibility that discarding cards from the hand could mistakenly be treated as moving cards from the hand into play, and therefore be prohibited by Horror House GX? My understanding is that discarding a card from the hand is neither playing a card nor putting a card into play, so it should still be allowed.
