Just got through the article, and thought it was extremely well-written and provided great insight. This bit was a nice touch, too:
"Explaining the power and usage of Gush would take an entire book."

@moorebrother1 It's just variance. Sometimes you can play perfectly and have the perfect deck and still draw three lands in a row when you needed to draw any spell, it's just part of Magic.

It's an interesting question that has a lot of facets to it. Generally speaking, you should try to make the most objectively correct decision, and if the results don't work out you just have to be okay with that because in the long run you'll come out ahead. Focusing too much on the results is an easy trap to fall into, and one you want to avoid at all costs. In Vintage especially, these decision points extend out well beyond the tournament itself because deck choice and sideboard selection are so important.

In your case, perhaps the decks that you have been playing have not been particularly well-suited to the metagame at the events you have played in? Or perhaps because you have been switching up decks you have not been playing optimally or have not had the time to really fine tune a list for your metagame? Perhaps you are putting too much pressure on yourself to put up the results that you think you should?

I do not think that Vintage is a top deck battle at the moment, it seems more balanced now than any other time in recent memory. Just my thoughts, no criticisms intended. Hopefully that helps at least a little!

Bomberman doesn't really work online, but kind opponents will see what you're doing and scoop to it.

I think 1-for-1 discard spells are actually a losing proposition against Outcome because their deck is so dense with threats, and cards that find more threats. Nabbing an Outcome or something early might slow them a turn, but I have not found discard to be particularly effective against the deck.

@revengeanceful

Stony Silence is probably the single best hate card against the deck, but I've found the best way to beat the deck is a combination of early disruption and a fast clock. Even if you land a hate card early, if you don't end the game soon thereafter they might find a way to draw out of it.

Serious congratulations on making it to the end of this monumental effort. I look forward to picking up a copy when it gets compiled into a book.

@hierarchnoble I don't think it works they way you're interpreting it. This only triggers off of instants and sorceries cast on your turn.

See also this thread in which Rich Shay graciously volunteered to put together a list of Vintage relevant cards to make sure they are included.
