r1 bye
r2 u/w standstill: g1: he shows me a tundra while shuffling so I choose to draw. I ddd for 4-5 turns just building up an army and never casting a spell, and then when he taps low for shackles, I probe him, he missteps, I probe him he missteps, i go land therapy, he lets it resolve, i nab his forces, see has has no more counterspells, and DR Primus, + therapy again to kill his shackles + a land, leaving him dead next turn to my army with no action.
g2: Expecting peacekeeper i sided in elesh norn. He keeps a hand with moat, EE and peacekeeper and no counters, He cant interact and thinks his perms are going to save him, primus for the moat, and forcing him to use EE and, elesh norn to kill peacekeeper and swing with some huge zombies.
r3: Lands with painter/stone. g1 I have a pretty explosive draw with Coliseum But by turn 3 he has Painter + grindstone + 3(tapped lands). I primus his grindstone, then therapy him killing his academy ruins, seeing that he has tabernacle in hand. He plays tabernacle, and draws living wish for glacial casm. I save my narcomoeba with my city of brass, and let woodfall primus and all my zombies die, Dread return primus killing tabernacle and pass with a like 12 zombies and a primus + ichorids in yard. He has no play except casm, go. I sac primus to therapy him, killing casm and swing at him for 20+.
g2:. Basically the same thing happens except he has EE and mazeinstead of tabernacle and casm I brought in the 3rd dread return so i had more options, but my draw wasnt as explosive. Primus took it home anyway.
r4:elves G1 i mulled to 5 on the draw, had a slow but fine pimp+thug hand, He went off t3 and had lethal coming at me t4 after i whiffed on my first 2 dredges.
g2: He plays a bunch of dudes, I firestorm him for his entire board, save an elvish visionary. Then I Iona green the next turn.
g3: he is land light and cant go off til turn 4, Im able to get down iona on green but his board is huge, and he is drawing to hardcast emrakul, Im able to get elesh norn out before he can draw emrakul and he loses.
r5: U/R/W stoneforge/lavamancer/jace type thing: Choose to draw since this is a "known" player and has a rep for playing control decks. g1: He has lavamancer + SOF&I. I primus his sword and white source, therapy his hand away and run him over.
g2: he mulligans, has no 2nd land and dies real fast.
r6: u/w standstill: I know the guy and know what he is playing so i choose to draw. G1 i just DDD and he cant beat it because thats just how the matchup goes.
g2: he gets down peacekeeper early, I therapy him hoping to nab his countermagic and return elesh norn for the win the following turn, instead I see wrath of god, so i have to dread return iona on white instead, and get elesh norn the following turn. I fade whatever outs he has and win.
r7: merfolk with maindeck SOF&I g1: I have a really nutty draw, multiple outlets, into multiple probes, into LED+Breakthrough, He concedes when he has no permanents in play and I have 26 power on the board on turn 3.
g2: he tanks hard on his 7 and keeps, I have 2xpimp, bridge, 2x needle, rainbow land, firestorm on the draw. I figure that his tanking had either means that he has no pressure or no counterspells. either way this hand is good against that. Turns out he has no pressure, but missteps my first imp and wastes me, I draw another land, and he dazes my 2nd imp. I try a needle and he missteps while beating down with mutavault. I resolve the 2nd neeedle and name mutavault figuring that there is no way he sandbagged relic for 5 turns. Obviously he plays relic(by this time I have a dredger in hand) I therapy him for lord of atlantis(he has no double blue) and instead see coralhelm+ surgical extraction(!). He plays coralhelm. Next turn I therapy him forcing him to use the extraction when my yard is land, pimp, therapy and nothing, no bridges no dredger.(he still has relic this whole time)he extractions pimp(!) I guess since I had no outlet and I would still have a therapy(the one on the stack) but it still seems wrong. he beats me down with coralhelm, and doesn't level so he can keep up relic activation mana(I guess). I draw a 2nd land, play it and pass. When he goes to level on his turn i firestorm away his coralhelm discarding Ichorid + my first dredger of the game, a thug. He passes back, I dredge 4 and hit another thug. I play the first thug and pass. he just passes back. I make a big show of going to my drawstep prompting him to use relic at the wrong time, He does. I rip breakthrough off the top and breakthrough for 1, he tries to misstep it, but it costs 2. I breakthrough into coliseum which I keep + grave troll which goes to the yard. By this time im at 5 life. I hold the coliseum to avoid wasteland and pass back. He draws and plays reejery. I play coliseum and pop it, getting a narco and some bridges, I therapy him for the misstep i know he has and get some tokens. He plays a LOA and passes back. I get back ichorids, and DR elesh norn for the win. This was a strange game.
r8: Goblins. g1: I keep on the draw, t1 discard grave troll t2 dredge, hitting stinkweed. he played t1 lackey, t2 lackey for ringleader then warren instigator so i have to go for it to not die + I know he has gempalm and warren weirding from the ringleader. The stinkweed dredge misses another dredger and I die. no action in my top 20 cards, this happens sometimes.
g2 he has has leyline and lackey into piledriver, play piledriver. shrug.
r9: u/w stoneforge standstill. I know the guy and he plays blue decks so i draw. g1: My draw is slow and my dredges are below expectation and i eventually just die to his batterskull + multiple plows.
g2: Again he has batterskull but i keep the game under control till i can find primus. Still this game take forever because of lifelink and him asking the jusge a question and then us not netting a time extension.
g3: I'm paired down this round , im X-1 and he is X-1-1 On turn 5 of turns he has no nonland perms, a hand of misty rainforest, and is facing down Ional on blue + woodfall. I cant do quite lethal to him(thanks batterskull!) Obviously he refuses to scoop even after i inform him that there is no possible way that X-1-2 makes day2. He wont hear it and I don't have much time to convince him since there are actual 4 judges watching the match who don't care about the fact that im getting fucked over and just want to go home or play EDH or whatever they do. So we draw and he obviously does not make day 2.
r10: U/W standstill. Since im in the draw bracket I just choose to draw, gotta stay on theme. He is u/w standstill and g1 is a joke. We both cast nothing and he just dies to ichorids + zombies.
g2: he chooses to draw(that in itself is a win) and has tons of countermagic for my early action + plow for my first ichorid. He gets out jace + crucible drawing an actual 3 cards per turn every turn foir like 8-10 turns, while I just dredge and pass. He sticks 2 peacekeepers, and i try and figure out how im going to win the game. After im able to therapy all his countermagic I have to primus away his shackles and his jace then pass, he brainstorms a bunch and passes back with me having 5 cards left in library including 2 remaining dread returns and a therapy. i dredge 4, hitting the 2 dread returns, meaning i know my last card is is therapy. Luckily i have been sandbagging a land since t1 for just this occasion. with just therapy left in my library, I use my last therapy out of the yard, which he missteps, then go for dread return on iona, which gives me 12 zombies. He counterspells it, leaving him with just 2 peacekeepers and 3 cards in hand and me with 12 zombies. I pass back, he upkeeps his peacekeepers and passes back. he has 2 forces in yard and 1 RFG(from the very early game) so i go land therapy naming counterspell, he shows me the last force, i flashback the therapy on force then dread return elesh norn and attack him with 10 4/4's with 0 cards left in my library.
r11: u/w stoneforge and ancestral visions. g1: I choose to draw(or maybe just lose the roll this round, dont remember) knowing he is playing control since he is a name player. he suspends an ancestral visions on turns 1,2 and 3, I miss on my first few dredges, he plows all 3 of my ichorids(not that this was unexpected i mean he did draw 9 extra cards) and sticks a jace. I die.
g2: I keep a slow hand and start DDDing, he goes t2 stoneforge t3 stoneforge in batterskull, turn 4 stoneforge in baatterskull and i just die, again whiffing pretty hard on my dredges.
r12: u/w stoneforge with standstill. g1 He has t2 stoneforge for sword of war and peace(!) while I am on the DDD plan and cant find any action, he hits me for 10 twice and i die on turn 6.
g2 i have a more aggressive LED hand and am able to run him over pretty quickly.
g3: Basically the same as g2
r13: Merfolk with stoneforge. g1 I beat him in a typical merfolk g1 where i just build a bigger board with ichorid and bridges and don't expose my bridges to cursecatcher until im ready to kill him.
g2: my one regret, I keep a really loose hand because it has double firestorm and do nothing and lose.
g3: he stoneforges up moartarpod(!) holy crap that card is good vs dredge, i get destroyed.
r14: Merfolk with stoneforge. This is the friend of my last round opponent playing the same deck. g1 he actual mulls to 4 and just loses.
g2 he mulls to 6 keeps a hand with no colored mana(he had moartarpod) and just loses.
r15: u/w/r stoneforge with magus of the moon. g1: I get dredging a bunch with probe and have coliseum next turn to finish him off but he sticks magus of the moon which slows the game down a bunch. eventually i slow dredge a bunch to find primus to kill his jace + white source and has to chump away his board and dies.
g2: before sideboarding he like mutters under his breath that he lost to dredge earlier even though he had tormods and surgical extraction. I pretend like i didn't hear him and ask him to repeat what he just said, he does, so its obvious that he has nothing. This is a terrible bluff(mindgame whatever you want to call it) and it totally backfired on him, i would have played more scared FOR SURE if he just said nothing but the fact that i got him to awkwardly repeat the hate cards meant that he had actual nothing. My suspicions were confirmed when he played ethersworn cannonist(lol) on turn 2. I was able to firestorm it discarding a grave troll, but he missteped the firestorm. I dredged 6 and played another land. He attacked with cannonist and a factory. I firestormed them both and it resolved. From there i dredged a bunch, and played and activated a coliseum to lock it up. He was pretty tilted and one draw step i dredged thug instead of troll so that i could cast it(so i would have enough guys to DR + rebuy my narcomoeba flip) he cliques me draw step, and puts thug on the bottom, I shrug and just dredge back another thug from the clique draw, and it was very over since he was so mentally out of the game at that point, also he was a dick to me and writes for starcity, so if you are so inclined you could figure out who this person is.
anyway i finished 28th with 11-3-1 so i won 400 and had a pretty good time. The deck felt perfect, every card was used and things generally played out the way I had drawn them up when i was brewing this list, although I think I just want to find a place for the 4th pithing needle in the board(or perhaps main, gogo sun titan.)
edit: and grats to our hotel room, especially reid and Ian who made t8 and 32 respectively.
