I see this is kind of a PSA/Rant, but earlier, I sat down for a quick and casual game of Commander at the LGS. It was Gruul Etali (me), Naya Dinos, Xyris Draw, and a very niche 5c Omnath Deck. Now I only have the one, deck, and the Omnath player knows it, as well as what it does (the deck's name is Etali Golos, because it's nothing but ramp spells, lands, and a few random niche cards that I like) and has played against it before; furthermore, I even explained that it was my only deck and that intended to use it. Everyone was cool with it and we began. The Dinos player built a crazy board and by turn 4 had boarded over 20 power of creatures (Grim Monolith and Thran Dynamo into Gitshath go BRRRR) and I attempt to deal with it with my own commander, with Etali stealing an Ertha Jo, Minds Aglow, the Dino players og Etali and my own Wild Wasteland, much less potent of a board state than the Dino player. The Omnath player at this point, decides that he is going to threaten to blow up my mana dorks/rocks/commander, to which is probably fair, but when I asked why my board (which was going nowhere fast, and they knew it) over the Dino board, which would've been a much more legitimate play. Their response:

"I know what that deck does, I don't want you at this table."

The PSA: This is a casual game. If you don't want me at the table, please just tell me. Don't invite me over if your intent is to bully me out of a game regardless of the situation. I really don't want to be at a table that does that. I'm here to have fun.

End rant.
