In the past few months less and less people have been playing Control Slaver due to the explosion onto the scene of the various Gifts Belcher decks (SSB, Gifted.fr, etc.). Yet this past weekend at StarCity P9 Rochester Control Slaver was the third most popular deck, after Worse Than Fish and U/W Fish, with eventual champion Ugo Rivard being one of the 14 people who piloted CS that day (myself being another of those people).
For reference, here is Ugo's build:
4 Goblin Welder
1 Mindslaver
1 Platinum Angel
1 Triskelion
1 Lightning Greaves
1 Crucible Of Worlds
4 Mana Drain
4 Force of Will
4 Brainstorm
4 Thirst For Knowledge
1 Ancestral Recall
1 Echoing Truth
1 Fact or Fiction
1 Gifts Ungiven
1 Mystical Tutor
1 Time Walk
1 Tinker
1 Demonic Tutor
1 Vampiric Tutor
1 Yawgmoth's Will
1 Black Lotus
1 Mox Jet
1 Mox Pearl
1 Mox Sapphire
1 Mox Ruby
1 Mox Emerald
1 Sol Ring
1 Library of Alexandria
1 Tolarian Academy
1 Strip Mine
1 Seat of the Synod
4 Polluted Delta
4 Volcanic Island
2 Underground Sea
3 Island
SB:
3 Arcane Laboratory
3 Pyroclasm
3 Blood Moon
1 Echoing Truth
1 Pyroblast
1 Red Elemental Blast
3 Rack and Ruin
While I disagree with some of the choices in his deck, he has a lot of versatility, and it obviously paid off. What was it that allowed CS to pilot through a field of Meddling Mages, Chalices and StPs to claim the top spot? For one I think it's much less mana intensive than Gifts Ungiven variants (Ugo's deck runs one, but isn't really a Gifts deck like SSB or Gifted.fr is), and while it hates seeing a Chalice for 0, it's less annoying than against those other decks. I also think his SB was very well-prepared for the Rochester metagame.
Putting Ugo's build aside, I'd like to talk about what I ran. Rather than running Shay-style Control Slaver like Ugo (albeit modified), I chose to go with Goth Slaver. As Ultima pointed out in another topic, the use of Accumulated Knowledge is at a real low right now. Since Goth Slaver has pretty much fallen off the Vintage map with the appearance of Gifts-Belcher decks, the only other deck that really runs AKs is Meandeck Oath, and not even that many people are running it, since Chalice Oath is also an appealing option, and it runs TFK instead. Here is the build I ran at Rochester:
3 Goblin Welder
1 Crucible of Worlds
1 Mindslaver
1 Triskelion
1 Platinum Angel
4 Mana Drain
4 Force of Will
4 Brainstorm
4 Accumulated Knowledge
4 Thirst For Knowledge
3 Intuition
2 Deep Analysis
1 Ancestral Recall
1 Time Walk
1 Tinker
1 Yawgmoth's Will
1 Black Lotus
1 Mox Emerald
1 Mox Jet
1 Mox Pearl
1 Mox Ruby
1 Mox Sapphire
1 Sol Ring
1 Mana Crypt
1 Tolarian Academy
1 Library of Alexandria
1 Strip Mine
1 Darksteel Citadel
2 Polluted Delta
2 Flooded Strand
1 Underground Sea
4 Volcanic Island
3 Island
SB:
3 Tormod's Crypt
3 Engineered Explosives
3 Seasinger
3 Red Elemental Blast
3 Rack and Ruin
My record was less than stellar, going 3-2-3. Yes, that's right, 3 draws... Two of them could've/should've been wins, since on the last extra turn my opponent finished somewhere between 1-4 life, and my Platinum Angel was on offense. I switched to the deck at the last minute after not playing it for a few months, so I probably could've played a bit faster, but whatever, you know what they say about hindsight,

. I'd make a few changes to my this build if I decided to run it again, but I'll get to those later.
In case anyone cares to know, my rounds went as follows:
R1: 0-2 vs. 3-Color Control (he wrecked me with Balance and then YWill+Balance, and 1st turn LoA both games)
R2: 1-1 vs. Control-MaskNaught (he finished at 2 life on the last extra turn, with Platz on offense)
R3: 2-0 vs. 3-Color Control (too much draw for him to handle)
R4: 1-1 vs. Gifted.fr (I finished with an active Welder and goodies in the graveyard, so with a few extra turns I probably could've pulled it off)
R5: 2-1 vs. U/W Angel-Standstill (really weird round, since my opponent made two big mistakes and got two game losses because of it)
R6: 2-1 vs. Transmute Artifact.dec (really interesting build; looked like so much fun to play!)
R7: 1-1 vs. BomberMan (again, on the last extra turn my opponent ends at 1 life, with me swinging with Platz)
R8: 1-2 vs. Stax (first turn insanity with Metalworkers, Defense Grids, Chalices, etc.)
Regardless of my record, which doesn't make such a compelling case to run Goth Slaver, I was resolving all kinds of Intuitions, AKs for 3 and AKs for 4 all day long, and they were just outstanding. Intuition is just such a bomb in this deck, whether it's finding 3 AKs if we need to draw more cards, loading up the graveyard with saucy artifacts (going for Crucible + Strip + Slaver/Trike/Platz was golden for me all day long) or finding an emergency Welder. I even had 2 Deep Anals in the deck in case I did face an AK-mirror, which didn't happen (in retrospect they should've been a Demonic Tutor and Welder #4). I did expect Meandeck Oath to show up in force, based on Smmenen's endorsement of it on StarCity as a good choice for SCP9 Richmond, and that runs Intuitions and AKs, but I guess I just didn't get paired against them (I checked on StarCity just now and 13 people played various Oath builds, so my guess was correct).
Based on what I saw at Rochester and the results, I think that the metagame is looking ripe for Goth Slaver to make a comeback. Whether or not it makes sense to run it over something like SSB or Gifted.fr I'm not exactly sure, but I just know that personally I love Welding in artifacts and winning that way, rather than comboing out. As many people have pointed out: Mindslaving an opponent once will many times be enough to end the game, or at least give you the time necessary to finish him off. I think that with the lack of AKs in the format our powerful draw engine can be unleashed without worrying too much about the mirror, and that Intuition just makes the deck even more nuts.
The changes I'd make to the deck if I were to run it again are:
-2 Deep Analysis
+1 Goblin Welder
+1 Demonic Tutor
I'd also love to put in a Pentavus, to have a 4-turn clock instead of a 5-turn clock (Platz, you know I love you, but you can be a bit slow). I'm debating whether or not to pull the Trike, since I didn't get paired against a single deck in Rochester where I really wanted him, but then again you can argue that that was because I was never at the top of the standings where the Fish decks were,

! If not the Trike I'm not sure what I should pull... Another Underground Sea might be a good idea, since I've now got the DT in there, but then again I do have Crucible of Worlds.
My SB was total ass for me, but that's probably because I didn't face any Fish decks. I definitely think 1 Tormod's Crypt and 1 Seasinger can come out, letting me add something like 2 Echoing Truth. Pyroclasm also seems really hot vs. Fish, so I'd make room for them (maybe cutting the Seasinger's altogether, since they come online a bit late).
I'd like to hear what other people have to say about Goth Slaver in the current environment, to see if I'm just crazy or if there's something to what I saw at Rochester. Anyway, I hope this sparks some conversation.
