Here's why:
* Game knowledge is part of the strategy: The game is designed to involve strategic decision-making based on your knowledge of cards and their effects. Asking your opponent about their monster's effect would remove that element of strategy and make the game unfair.
* Unclear language: Some card effects are worded in a way that may not be immediately clear. It's your responsibility to read and understand the effects of the cards you're playing against.
* Gameplay rules: The official Yu-Gi-Oh! TCG rules do not allow players to ask their opponents about the effects of their cards.
How to figure out your opponent's monster effect:
* Read the card: Pay close attention to the text on the monster card.
* Use card database resources: Websites like Yugioh.fandom, Yugioh.pro, and others provide comprehensive information about card effects.
* Ask for clarification on wording: If you're unsure about the specific wording of an effect, you can ask your opponent to clarify the meaning. For example, you can say "Can you explain what happens when your monster is attacked?"
Remember, understanding the game's rules and card effects is a key part of playing Yu-Gi-Oh! TCG successfully.
