I have been putting a lot of pressure on myself to play better and do better as a Magic player
well, that's part of it. you might be too focused on results and playing better to accurately diagnose losses.
first of all, stop entering tournaments with the expectation of winning or top 8ing. that expectation is probably driving you nuts.
once your emotions are less in play, you can start breaking down games and figuring out why you won or lost a particular game.
one mini-game I play with myself inside of a game of magic is to think about which cards would be the best possible topdecks at that given moment. this also helps me with card selection when playing cantrips. if you find yourself frequently in situations where you're digging for a 4-outer or worse in a losing board state, then consider playing a different deck.
one last thing, you're playing stoneblade which is one of the most "fair" decks out there. your card quality is pretty flat and your cards tend to be more reactive. that means you have to play very solid to maximize each card since you can't rely as much on a broken card to bail you out.
"Bad" players assume they play perfectly because they lack the capacity to identify their misplays. From there, it follows that they will blame either the deck or variance for their mistakes. I would say the best players have a much more balanced view, assigning "fault" between the player, the deck, and variance to partial amounts while looking at what they can change to maximize their win percentage.
@chubbyrain When I played at Eternal Weekend last year I had one of my opponents show me her sideboard choices and then she went play by play to ask me what she should have done differently.
I did that round 1 and round 2. And, both of my opponents could not point to an error. I acknowledge your point, but there is something called bad luck.
We all spend a ton of money to "enjoy" this hobby. When is it not enjoyable I have to take a step back and re-evaluate. And, that is exactly what I am doing here.
You do realize that 3-2 is 60% an a great win rate right? Pro Win %
The best players in the entire world are around a 65% win rate are the GP+ level. Losing around half the matches of Magic you play is completely normal. If you don't like that then I don't think Magic is the game for you. The first thing you have to accept as a Magic player trying to improve is that you will lose ALOT and you will continue to lose ALOT until you are Owen Turtenwald where you will still lose ALOT
@moorebrother1 I agree, the primary reason to play magic should be for fun. If you are not having fun, you really should step back and re-evaluate.
That said, I don't think the approach of "asking your opponent to tell you what you did wrong" is very effective. Your opponent doesn't have perfect knowledge of every decision you made. They don't know what your other options were. They may not know how to pilot your deck. Or they may not be willing to tell you because they don't want you to beat yourself up about it after a loss.
This is especially true when it comes to Xerox, in which many of the decisions are made in hidden zones (hand, library, etc), and many games go long. Do you remember every scry decision over the course of a game? Every spell you could have countered, but chose not too, and which countermagic you could have used? Because your opponent is not privy to this information.
For the record, I didn't want to make this post about you. I know you were the OP, but the headline seemed to be asking for a general account, and many people were weighing in with their own perspectives and approaches. If you meant this post as a way to make up your mind about the Vintage format, that's fine, but I don't really have anything to contribute.
@IamActuallyLvL1 Most Vintage is not really played at a GP+ level. Joe Brennan mentioned that he has a 80% win percentage in his events. Joe is a great player, but such a win rate should be unattainable over the long run in a more competitive setting. As you said, pros tend to plateau at 65%.
