Well, I heard of an MTG LGS where the tournament organization was a complete mess. They didn't have proper pairings set up. Some players ended up having to wait for hours just to start their first match, and the judges were unhelpful and seemed clueless about the rules. It really ruined the tournament experience for a lot of people.
Sure. In one store, the playing area was always dirty and smelled bad. There were food crumbs everywhere and the tables were sticky. It was really unpleasant to play MTG in such an environment.
There was a story where a player entered a big tournament. They had a great deck that they'd been working on for months. But on the day of the tournament, they realized they left a crucial card at home. They were so disappointed and felt all that preparation go to waste. It was like a horror story in the MTG world where all your plans fall apart at the last moment.
A great MTG story is that of the origin of a very powerful deck archetype. A group of players were experimenting in their local game store. They came up with a unique combination of cards that no one had really thought of before. This new deck was so effective that it started a trend in the MTG community. Everyone was trying to either copy or counter it. It changed the meta - game for a while.
Well, I'm not sure of the specific 'Homebrew Commander MTG horror story'. But generally in MTG, a horror story could be about a really unbalanced homebrew commander deck. Maybe it had some super - broken combo that made the game completely one - sided and unfun for everyone else at the table. For example, a combo that allowed infinite mana generation and instant - win conditions, ruining the competitive spirit of the game.
A possible horror story could be a homebrew commander that was accidentally too powerful. It could be a situation where a player thought they were making an interesting and balanced commander, but when they played it, it just steamrolled over the other players. For instance, if the commander had an ability that dealt excessive damage directly to players with very little cost or restriction.
One of the best MTG stories is about a player who built a really unique deck from cards he found in a dusty old box at a thrift store. He took it to a local tournament and managed to defeat some of the top players with his unexpected combinations. It just goes to show that creativity in deck building can lead to great success in MTG.
A memorable MTG story is the one where a player got a very rare card by chance. He then built a deck around it. In a tournament, he faced tough opponents but the synergy of his deck with that rare card was amazing. He managed to win several games just because of the unique plays the card enabled. It was a story of luck turning into great success.
