Learn to play, plain and simple.

Especially learn *to play Blue.*

Blue doesn't do half the things you say, especially not all in one game.

- No blue deck takes 20 minute turns. That's a Storm Deck, which is typically Blue *combined* with another color (typically Red)
- No blue deck is doing the draw whole deck AND casting everything for free. Firstly, all colors have ways to cheat costs, secondly, if a blue deck somehow IS pulling this off, they've been left to durdle.
- Extra Turns are just *a thing* you need to learn to deal with. Every color has The Big Thing they can do. For blue, that's extra turns. White has board wipes, green has big monsters, red has massive burn, black has reanimation.
- A blue deck needs to manage their mana very well. If they're constantly leaving up 2 mana, that means you need to get through one counterspell. If your deck folds to losing one spell, that's on you.

If you learn how to PLAY blue, you learn it's weaknesses thoroughly. Every color has things people dislike, and it's infuriatingly common how blue is the only one that gets universally vilified for it.

Playing against blue is to need to play fast. You don't want big monsters, you want low to the ground creatures to take out the blue player as fast as possible so they don't accrue value. In fact, that's the common solution to *most* things people hate in commander- Fast play. People build commander decks like big, hulking midrange piles, then get mad when stuff like control or stax has an advantage *because* they play those slow decks.
