Is it angle shooting or punishable for a player to announce 'I have Time Warp' (without playing it) to fish for a reaction from their opponent?

Ruling: Simply announcing you have a card or revealing private information is not angle shooting or punishable under current tournament rules, as players are allowed to reveal private information. However, if a player reveals a card in an ambiguous way that makes it seem like they are playing the card when they are not, judges should hold them to having played it.

Sequence:

• Player may reveal private information (including cards in hand) without playing them
• Opponent is not required to respond or reveal any information
• If the reveal is ambiguous about whether the card is being played, judges should rule the card was played
• If the reveal is unambiguous (e.g., holding card up without placing on table), opponent revealing information in response is their own mistake

Nuances:

• Bluffing (positioning as if you have something without lying about game state) is allowed and distinct from angle shooting
• Lying about private information appears to be allowed under current rules (though this varies by region - China explicitly prohibits lying)
• Revealing cards to save time when showing deterministic/overwhelming game states is common and acceptable practice
• If a player explicitly asks for information or a concession while revealing (e.g., 'I have Time Warp, wanna move to game 2?'), that would be angle shooting
• The key distinction is whether the player misrepresents what game action is occurring
