I drew 30 cards without getting a second swamp. It seems results-oriented to switch to 8 swamps since that's 8 is already an average of 1 in 5 cards being swamps. The deck's curve is pretty aggressive too. If I had gone 25 cards and gotten a swamp I would have won earlier. I actually eventually won only b/c my opponent ran out of cards!

You are right though, this game was super fun and if I had made any misplays he probably would have won. Hearthstone is garbage, the title was just a meme lol. I did originally quit MTG because at a certain level, if both players play perfectly it comes down to mana flood/screw and it sucks to see that in pro play
