In all fairness, the instructions you actually need to know to play the game could be summarized in a single page (with the caveat that there will be a lot of edge cases that won't be adequately explained there); tournament judges and, to a lesser extent, tournament players are the only folks who need to know the majority of what's in that PDF.

That said, the game is super archaic and hard to learn, and any player who thinks otherwise is probably either playing only at a super basic level, or just isn't considering how long they've been playing and how much nuance they've accumulated. Sorry you had a shitty experience; your friends absolutely should not have tried to throw you into the deep end like that. You sound like you already know, but to reiterate it, this was absolutely not a failing on your part and was 100% your friends' fault.

If you actually want to try the game (and I completely understand if you don't), you can go to a game store that sells MtG products and ask for a (free) intro deck. They're small decks with simpler cards and a booklet explaining the basic game rules that can be helpful to learn the game.

There's also Magic Arena, the computer game version, which really does a pretty good job of teaching the game. If you don't mind that format, I'd absolutely start there.

Lmao, as a long time player, you really got me on the "turning my cards sideways for 2 seconds" part. It really is like that.

I would never throw someone into a group setting to play like that on their first time. Total madness.

The game was originally designed to be played 1v1 and group play was meant to spice that up by adding chaos and leading to wildly complex scenarios.

It's honestly a really fun game, but you have to teach people way slower than that. I have a couple training decks without all the card types to teach the basic concepts before ever getting into the complex stuff. Throwing someone in at the deep end like that just seems like a good way to make sure they never wanna play again.
