Thank you guys for congratulating me. Ill give a brief break down of my battles, it was only 12 people, so it was cut to top 4 instead of top 8.
First match i faced was mono red stax (I think...he was playing welders). First game i had a hand with a little dispruption, and was able to sac hexmage to dark depths to win by turn 4. lucky me. second game i decided to side in the 4 bitterblossoms, and pithing needle, taking out helmline combo. This proved to be the right move, as we both played out our hands a little bit, he resolved lodestone and two smokestacks with a welder in play. Due to bitterblossom, I was able to keep up with his smokestacks and chump block his golem until the entire board was clear. From there, I was holding hexmage and dark depths in hand. i played those out, he played strip mine, i play pithing calling strip and win on the next turn. that was a really fun match to play.
second match I was up against a nice guy playing tog. First game involved going back and forth dropping lands, i get hexmage and dark depths into play, he attacks with tog trying to bait me into blocking with hexmage, i let the dmg go through. next turn (like turn 4 or 5) i sac hexmage to dark depths, he plays fire/ice tapping my marit lage to hang on for one more turn. he must draw about 15 or so cards next turn which makes me very nervous, but draws no answers (bounce). I win next turn. I don't think i sideboarded anything in for this game, feeling content with the match up, he goes to work bringing in cards from his sb though. Second game I have leyline in opening hand, which is good since I know he was running intuition/AK draw engine as well as yawgmoths. the game plays out like the first one, with me swinging for lethal with marit lage.
third match ended up being ubg tezz/planeswalkers. first game on turn 1 or 2 i sad sac removing a tinker fatty, tezz, and jace. we continue playing, i think i have this game in the bag. about turn 4 or 5 he gets infinite turns and asks if i will concede this game. i say i will scoop if he shows me a wincon. he has a jace in hand, so i scoop game 1. Again, I dont side anything in because the decks best match up is tezz (it was pretty much designed to beat tezz). Game 2 i get a marit lage into play by turn 3, and he scoops. Game 3 I started a little slow, i lead with a little disruption and slow him down, and sac a hexmage to kill an early played jace. i dont draw much after this. i assemble my hexmage and dark depths, pass the turn, waiting to break at the end of his turn. he plays his 2nd jace this turn, and misplays by attempting to unsummon my hexmage, i respond my sac'ing to dark depths, and win next turn.
fourth match i ID with another guy who was 3-0 as we were both undefeated and guaranteed to make it to top 4.
we contemplate a t4 split, but one player requested we play it out so we did. this is when i played my first true mud deck.
i knew he was playing mud, he knew i was playing mono black.
game 1 i lead with some disruption via thoughtseize and wasteland, but ultimately i should i have mulliganed the hand as it did not have much gas in it. he resolves a razormane masticore and i dont draw anything the next 4 turns and he takes game 1. i side out helmline combo for 4 bitterblossoms and a gatekeeper, and take out sad sac for another gatekeeper, and i beleive i took something else out as i believe i added in a couple edicts as well. game 2 i keep a hand i shouldnt have, it had 2 wastelands but only 1 black mana, i state i shouldnt keep the hand i have but i am probably going to, he says the same thing, and i assume from this he is vulnerable to wasteland. I play wasteland, go, he says uh oh, plays shop, trini, i kill shop, but trini resolves, he passes the turn. i play a second wasteland, pass the turn, he plays ancient tomb, passes. i kill wasteland, drop my lonely black, and pass again. i remember i had both a hexmage and a ritual in hand, but due to trini, i was locked out. he play draw go for a couple more turns, and he ends up resolving a chalice @ 2. from here, there is honestly no way this deck can win with a chalice at 2 and a trini in play. This deck is all 2 drops. I make him kill me, and he does.
I went 3-1-1, and the funny thing was, this was a borrowed deck. i went into this tournament planning on playing a GWSx/TPS hybrid and brought my binder of rares and collection of cards to the tournament, but i forgot to bring my deck box, d'oh! A very nice fellow said he had an extra mono black deck if i wanted to play it, and i did not want to walk away from an hour drive empty handed.
I was very pleased with how the deck played, but really, the lack of artifact removal is absolutely killer (as shown in the MUD match up). Other than gate to phyrexia, i do not believe there is a single way to get rid of artifacts requiring black cards. From here, there are 2 choices, either run nev's disk (which i think is far too slow and expensive), or splash another color. You could splash green for goyfs and oxidize/nature's claim/krosan grip, or blue for more card draw and bounce. Or splash white and include academy rector and divine intervention as another wincon with hexmage

(kidding, kidding). Running with the green idea, i came up with a decklist today that would be B/G dark times/do you fear death/etc. here is the deck list i came up with.
4 wasteland
1 Strip mine
2 Urborg
3 Dark depths
3 Bayou
1 Forest
4 Swamp
4 Verdant catacombs
4 Vampire Hexmage
4 Dark Confidant
3 Tarmogoyf
3 Duress
4 Thoughtsieze
1 Vamp Tutor
1 Demonic Tutor
1 Necropotence
3 Null Rod
1 Nature's Claim
4 Dark Ritual
2 Oxidize
1 Dem Consult
1 Diabolic Edict
1 Life from the loam
1 Black Lotus
1 Lotus Petal
1 Mox Jet
1 Mox Emerald
Sb
4 leyline
1 helm
1 chains of meph
3 gatekeeper
2 edict
2 pithing
1 rav trap
1 sad sac
i wanted to fit the emissarys of despair in there somewhere, but i couldnt find a way to make it fit. the helmline combo is what got pushed out of main deck into the sb as a consequence of splashing another color. i wasnt too happy about letting this wincon getting pushed out of the main deck, but i believe that with green, the beating with goyfs becomes the replacement wincon (as before the beating with hexamges and/or bob isnt that intimidating or quick). There is now a way to stop mud decks, as your gofys will most likely be able to kill lodestone golems and/or oxidze/nature's claim will also be able to destroy chalices, trinispheres, tangle wires, and other lock mechanisms.
The SB can be tuned more finely depending on your meta, so you could take out what you want and add emissarys, smothers, perish, damnation, etc. i think smother would be the best card to run in the side to counter fish, because you are also running edict and gatekeeper, and with smother you can kill their goyf (you know they wont sac it to edict or gatekeeper), and none of these are stopped by gaddock teeg. not to mention you run your own goyfs, and their only way of dealing with marit lage is to let you gain 20 life, which should be more than enough time to get another depths into play, or cast LTFL and get depths back from the GY. I also believe LFTL is better than crucible, as its cheaper. Another option would be to run grim discovery either in maindeck or sideboard. let me know what you guys think.
