Quote from JayC » 6. Win with class. It's just as satisfying and you won't create a weird tension between you and your newly defeated opponent. "Good game". Sincerely, say good game. It doesn't matter if they played well, or if you played well. It doesn't matter if you made mistakes or they made mistakes, say it. If your opponent is okay and wants to talk about situations, great. You might be able to make suggestions for one another on card choice, play choice, etc. If your opponent doesn't look talkative, be perceptive and let them be. Sign the slip and turn it in.
Quote from bateleur All of the above are assuming I'm in the right colours. Strangling Soot drops out of the top five if I can't support both colours.
