Does it ever happen to you, expecially with less experienced players, that you have to explain how a card, a rule, an interaction works and it is a challenge to convince them that it is like that? Sometimes even with basic concepts, like the fact lands are (almost always) colorless or commanders hit their destination before eventually being moved to the command zone.

The other day I had to explain that damage coming from two creatures fighting is noncombat damage, which was relevant since I had a [[Blessed Sanctuary]] in play. In his mind the point was that fighting is a form of combat. It took a couple minutes to have my opponent accept it and he didn't even look that sure about it.

Another time I used [[Gale, Waterdeep Prodigy]] to cast a sorcery at instant speed from my graveyard (by casting an instant cantrip and triggering Gale), and again it took a few minutes to convince my opponents I could do that because Gale is giving me permission to do it. I also brought up the example of [[Oskar]], who does a similar thing by discarding cards. Again I'm pretty sure in the end they accepted it to let the game go on, but I was left with the feeling they thought I was screwing them over.

Does this ever happen to you? Do you have a story to share?
