Went 3-4 at the Dallas Standard Open this weekend playing Mono Red Aggro. I dropped after the 7th Round cuz I was hungry as hell and I knew I was out of the money.
It was a fun experience, it was the first time I'd been to an Open or anything more serious than Game Day at the LGS. The $50 entry fee ensures there are no "Whoops, I accidentally showed up and I don't know how to play Magic" people, everyone there was out for blood, but I still met some pretty cool people. Although having said that, I did have myself "lol newb" moment, when I found out that tapped creatures deal combat damage (they didn't back when I used to play 5th Edition). Somehow that had never come up since I started playing again. Oh well, you live and you learn.
