Played on 4/23/22:

I know there's a lot of incentive to play 3-color decks but I really think playing around good rares in 2-color aggressive decks may be the way to go (unless you get good obscura stuff). Vivien's about as amazing as I expected and this deck plays similarly to Hour of Devastation Mono-Red; unblockable tribal. Plasma Jockey and Sizzling Soloist make a lot of your attacks virtually unblockable as you crash in every turn, which is really fun for me and me alone.

Went 2/2, but had a few hiccups that caused it to be such. I think it could have gone 3/1 pretty easily. Very fun!
