This is a teensy bit of a brag post.
So I went into the Grandmaster's Gauntlet, don't have Quake, so I was like what am I going to do. Low and behold MSD solos the whole thing without Quake (not surprised). Anyways, inspired, I hopped into the Grandmaster's Gauntlet with a similar team. The only difference was Ghulk instead of Namor because I don't have Namor.
I didn't go for a completion run but I did manage to solo Doom with a 5/30 5* Apoc. So needless to say, I was pretty happy. It was my tenth try, but most of those tries I just died without getting Doom down even a single%. The only other try that went super well I got him down to 8% and died. A few others I got him down to 85%.
So, here's a little clip of me finishing him off. I am not looking for any sort of congratulations, just wanted to share that I am now officially better than MSD who needed a r3 6* Apoc

I jk of course!
