So given that I've been loving the Golgari Aristocrats list to death, I figured I had to take this for a spin. I ran it against the AI for awhile and ended up making a couple quick alterations: -2 Elvish Visionary, +1 Nissa, +1 Ob Nixilis. I just wanted a couple more bombs. Time will tell whether that was dumb or not, but obviously I'm interested in any opinions.
Got in eight games against human opponents, went 7-1. The one loss was to a Golgari Elf deck that just had a ridiculous draw; there was no winning that game without Languish. That's not a recommendation to put Languish in the deck, for obvious reasons. The wins played out in a few different ways. I played a couple of games against a Dimir aggro-control deck that was semi-interesting. I tried to play the beatdown role in both, and almost didn't recover. What I found against that deck and the couple of control decks that I played against was that the games turned into grindfests every time, and the whole game turned on resolving and abusing the key spells. They were the usual suspects: EvoLeap, planeswalkers, and Smothering Abomination. Once I realized that my real goal in those matchups was just to set up a big Husk/Abomination turn rather than to play out my creatures quickly and apply pressure, the matchups fell into place. You mentioned in your Diaries post that the deck can play almost a combo role in some matchups, and I was surprised at how true I found that to be. More so than the strict Golgari version I've been playing, certainly.
Against aggro, things went more or less as expected. Block some early guys, Husk shows up, he eventually dies but buys enough time to get EvoLeap online or get Abomination out, win from there.
The one thing I'm still trying to decide is whether the red splash is worth it. Act of Treason is fantastic at times, but against the decks I played, it felt win-more. I'd have traded all of them for smoother mana and a couple boring old-fashioned creature removal spells despite the obvious synergy that Treason has with everything else. BUT: I didn't play against Ramp. That seems like the matchup where Treason would shine, so I'm not recommending dropping the red (at least not until I get a lot more games under my belt with this deck).
Thanks for posting the list, the Aristocrats decks are currently my favorite in the BFZ metagame. It's almost certainly not as good as Ramp, but it's so much more fun. I'll update with more thoughts if I have any new observations.
