You can see my MTGO decklists (Nykthos Ramp = Mono-Green) https://www.mtggoldfish.com/player/azax. I've been enjoying Mono-Green but haven't had a chance to play it in a "serious" event yet, and I'm worried it's not as good as Phoenix.

Mono-Green with e.g. a white splash still counts as Mono-Green for the purposes of this market.

The tournament is at 6am on a Sunday, which has historically been a nontrivial ask for me to participate; I haven't played either of the last two showcase challenges this season, though I did play most of them in the year before that.
