I beleive in SOTG. I think it applies to playing and trading.
The Spirit of the Game is composed of the following tenets:
- Fun: The Pokémon TCG is a game, and games are meant to be fun for all parties involved. When a game ceases to be fun, players find other things to do.
- Fairness: Games cease to be fun when players break the rules to achieve victory. A player should prefer to lose a game than to win by cheating.
- Honesty: Players of any game should strive to act honestly while playing that game. If a player inadvertently breaks a rule during a game and becomes aware of the error before his or her opponent or a judge, that player should make the opponent and the judge aware of the misplay.
- Respect: Players, spectators, and staff should be treated with the same respect that players would expect for themselves. Distracting an opponent or a judge to gain advantage shows disrespect to everyone involved in a Pokémon TCG event.
- Sportsmanship: Winning or losing with grace is vital to the enjoyment of a game. The desire to continue playing a game can be soured by players that berate their opponents after winning or losing a match.
- Learning: Players should strive to help each other increase their Pokémon TCG play skills. It is not a player's responsibility to make his or her opponent's plays for that opponent. However, discussing strategies, offering deck tips, or constructively critiquing game play decisions after the match has been completed helps both participants to become better players.
