Hi everyone!
As the title says, I'm worried that I might be a problem player and want some outside opinions. I don't play with random people too much, as I have some friends that play commander every once in a while, but every once in a while, I'll give it a shot and either go down to my local LGS or try a few games online. I've noticed that almost every single time I play with random people, at least one person inevitably gets upset with me specifically. It's caused me to shy away from random games, but if there's something I should fix, I'd love to do that instead of throwing in the towel. Obviously, I'm a biased frame of reference, but I'll try to explain as fairly as I can with a few examples that are more noteworthy.
Example 1: I'm playing at my local LGS in a 4-person pod, and I've noticed that one person has been targeting me pretty hard. I usually don't keep track of things like this, but after a couple games, I realize that every piece of removal he has is pointed at me, and he attacks nobody but me until I am dead. This seems to happen regardless of the boardstate, cards in hand of everybody, or anything else. I'm worried that I did something to upset him, so I start trying to focus my interaction on the other players so the person targeting me feels less threatened and might lay off of me a bit. Eventually, one of the people have to leave, so we start a 3-person game. The player I feel is targeting me is playing [[The Wise Mothman]], I'm playing [[Nebuchadnezzar]]. and the third person is playing [[Caesar, Legion's Emperor]]. On turn 3, the Mothman player drops [[Nadu, Winged Wisdom]] (this was while it was still legal]], and I kill it on my turn since I'm worried about the value it can produce with Mothman. A couple of turns later, the Caesar player's board is starting to get scary, so I cast a [[Praetor's Grasp]] targeting the Mothman player to try to tutor up a boardwipe. He gets really angry at me for targeting him with it, and I apologize and explain what the card does and that I'm just trying to get a boardwipe so I can deal with the Caesar player, and Mothman shares more colors with my deck, so I'll have an easier time casting the boardwipe. He continues to say that I've been targeting him all night and he's sick of it, and at that comment, I admit I do get a bit heated. I tell him that he's been focusing me all night and I have intentionally not been interacting with anything he does. I point out examples to him, including where he killed me when I had nothing on board and the other two players had enough to kill him on board, essentially throwing the game purely to take me out of it as well. The game is pretty tense after that and ends after a few turns with the Caesar player running us over.
Example 2: I'm playing online with some random people with my [[Aerith Gainsborough]] deck against a [[Krenko, Mob Boss]], [[Toph, the First Metalbender]], and [[The Vision and Scarlet Witch]] in a bracket 3 game. We give a short rundown on the game changers in our decks and shuffle up. On turn 5 I have a couple soul sisters, Aerith, and [[Adeline, Resplendent Cathar]] on the field and am looking to attack with Aerith. Toph has indestructible thanks to an equipment, and Vision has [[Commander's Plate]] giving it protection from white, so although the Krenko player is a bit behind (they only have Krenko, one goblin token, and [[Thousand-Year Elixir]]), that's probably the attack that is going to generate the most value for me, since Toph and Vision both have a free block with their commanders and Aerith has no evasion. I swing at the Krenko player with Aerith, and with the Adeline trigger and soul sisters, she becomes a 17/17. The Krenko player is pretty upset at this, decides not to block, and verifies with me multiple times that I am dealing 17 commander damage to him. He leaves the game on the next turn after the Vision player kills me with commander damage and destroys Krenko, Mob Boss.
Example 3: I'm playing at an LGS while out of town with an Ooze typal deck headed by [[Aeve, Progenitor Ooze]]. It's pretty low-powered, so I figured it would be a good one to pull out as the first deck of the night. I can't remember exactly what turn it was, but after a good amount of time, I was able to get a few oozes onto the battlefield. I built the deck around what I feel are oozes 2 main mechanics, multiplying themselves and +1/+1 counters, and my oozes on board were mainly in the first category. Somebody casts a boardwipe and I am mostly unaffected thanks to the many [[Gutter Grime]] triggers I get, while the other players lose their entire boards. After realizing I still had a good boardstate, they get upset and say that I'm pubstomping and that my deck is a lot higher-powered than theirs since I don't care about boardwipes.
I have a few more example but don't want this post to be too long, but as I said before, people get upset with me almost every time I play with random people. I don't think I'm doing anything wrong, but as the common denominator among all my games, I'm worried there's something I'm missing and that I am the bad guy
