Yeah I would focus the sideboard a little more for control and monoblue matchups if you plan on going to an unknown meta. For you it seems like you have a fair amount of control matchups, so I'd up the Duress to a solid 4 of in the sideboard.
Also how has Scuttling Doom Engine performed for you. Personally, I removed it for a 2nd Hornet Queen. I am just so impressed by it. It's good in every match up.
My meta is either 75% control with 12.5% aggro 12.5% midrange or 80% mono black 10% aggro 10% control. It's like everyone jumps on the most recent SCG top 8 deck list. And I ended up siding it out almost every match to be honest. Tonight at FNM I was able to kill it with garruk to kill my opponent. And I was able to whip it back to get a quick 6 damage in but I think I'm going to get another hornet queen. The genesis hydras are just the best. They bring me back from a land flooded game to winning or just bring me over the edge to break a stalemate every time. Even if they get countered or killed. So powerful and underrated.
This is the list I brought to my LGS tuesday night magic, I went 4-1-1, to top 4 split. This is the first time I am playing it in a sanctioned event aside from dabbling around on cockatrice.
Round 1, Played against U/w Control. Kinda hard match up haven't figured it out yet with this deck. Both games went to time, with him just having way to much card advantage but I was able to make him sweat out and really work for the win. This deck is definitely a competitor for u/w need to tweak the side board a bit more. 0-2
Round 2, played against Bant Walkers. This match up is relatively easy. Ramp out quick get thoughtseize the kiora away. Keep the downfalls open and coast in for the win. Nissa was an all-star in this game coming down and bringing in a hornet queen with her. Reaper is just too strong, hexproof in response to an early game dsphere. Genesis Hydra into a garruk. Just a great match up. 2-0
Round 3, played against U/w midrange. It was a homebrew, it ran azorius arrester, Lyev Skyknight, Tidebinder Mage and the typical mono white aggro dudes, with a Lavinia and Ephara a few negates, dspheres, and banishing lights. It was a really fast deck. Game one I got stomped. Game 2 I stomped him. Game 3 he got me to 1 when I ripped a drown in sorrow with a nissa, courser, and polukranos on board. Wiped his board he had no hand, and just beat face with darksteel citadel. 2-1
Round 4, played against America Control. Game one I lost, Played aggressive to feel the deck out and see what he had. Game 2, dropped a mistcutter for 7 with nissa and Hornet Queen out. Thoughtseize and duress took care of the stuff I couldn't deal with. Game 3, Had 2 reapers out with a whip, against his 2 scuttling doom engines. Swung in gave deathtouch in response to him blocking and then regenerated my dudes with golgari charm kept drawing threats got him to 6 and he verdicts, top deck a mistcutter for 8.
Top 8, played America Control. I won 2-0 he didn't draw lands game 1. Game 2 he didn't see a single verdict or Rev. turn 4 mistcutter for 6 made him cry.
I merged a few deck lists I have seen and added cards I felt fit better and will do better against the current meta. I am also looking at the best possible sweeper, currently I like Scuttling Doom Engine but am looking into Sylvan Primordial, Soul of New Phyrexia and other bombs of the sort for late game pushes.
They actually performed exceedingly well in all of my testing. They perform as one drops just as Judge's Familiar and Cloudfin Raptor. Granted Cloudfin Raptor has evolve and the ability to grow big. The bestow effect of a siren has saved me from stormbreath, Brimaz, Advent of the Wurm tokens.
I read an article by Frank Karsten about some standard brews he had. And he had a blue/black devotion list that really stuck out to me as something that seemed extremely fun so I proxied it up and gave it a few games. I fell in love with it. It is so much fun. But as to any brew there are some downsides to the deck. I made some small changes to his list and would like to see what you guys thought about it. Any feedback is welcomed. I also have not thought of a sideboard as of yet.
