This was literally the first Slay the Spire 2 run right after watching that video. Caleb's video is called "How I'm Winning 92% of My A10 Regent Runs". Even as I played the game I checked back to the video to see if I pick the proper cards, which is why this is a quite long run. Also, the more I play with this game, the more I believe a single potion used at the right time can win you a run, which is why I kept Gigantification Potion to win the final fight.
