Ok, my results, all around lvl 30 on steam.
1st match against 4 colour, he gets three Mosses in a row (right on turn 4 ofc), he gets ulamog on turn 7, i've got tons of measures against him, but no mana. LOSS.
2nd match against Sultai Control (no mill sighted though), nearly no creatures from his side, he dispersed my Nixilis one step from ultimate, counterspelled Ulamog, i Summoned him back, to be dispersed and harbringer of tided two times in a row, but then Ulamog does his work by milling him in spite of his fogs. WIN.
3rd match against goold old white agro, he gets all the origins weenies and i don't get any cheap or mass removals in time. LOSS.
4rd match against Golgari processors. Got a bit nasty because of Blight Herders but can succesfully stall untill Ulamog. He does his work. WIN.
5th match against selesnya. Maybe i'll find ramp here at last? And true enough i met with Revelation, Nissa herself and Kazandu. And ofc Evo Leap. I Flared Gaiea, he brought her back with Emeria's Shepherd with my Reprisal somehow not being able to deal with it in time (maybe missplay, maybe a bug, maybe intended). I had to do two Languishes (see, they work
) but he got a second one. Dealt with it with a lucky draw of Planar Outburst then after some turns Tragic Arrogance'd Evo Leap. Two Empty Trones nearly did it for me, but an Edict and a second Outburst helped for a time. He gets his Emeria's Sheperd back with Guardian of Murasia, i could only maradeur him, but maybe that was a missplay, because he ofc brought him back with Emeria. I managed to flip Liliana, but that didn't help. He brought Gaeia back with Emeria and went for lethal. LOSS.
6th match against Thopters, neither of us did anything wrong, just won very, very, very narrowly (he lacked one instant card to finish me off with Ravaging Blaze. Won with Gideon and the Vampire Land. WIN.
7th against Gegliosh in all his glory with his RDW boyz. Hadn't anything ueful untill languish, stabilized on turn 4 with 5 HP. He left and i finished the game easily with Vent and Liliana's Lifelink. WIN.
8th again RDW, different player, similar game, but not enough removals. LOSS.
9th game against a lvl 40 chap with a strange RGW deck with a renown theme and +1/+1 tokens theme and a ramp/acid moss theme. Made the radical step since the deck isn't anyway destined against agro to cut two Myers for two Emeri Shepherds (which i'm still on the fence since permanents aren't this deck's theme) but he served me well. Easy WIN.
10th and last game against Golgari Ramp, at last, again a ramp guy. Dealt with Titan and Gaeia, never seen Ulamog or From Beyond but sure he had those. Relatively easy WIN.
So 6-4 for now and, well, you notice the 2 ironic points. I've ran into ramp all day but met only 2 and a half ramp decks. And for an AntiUlamog deck i won with Ulamog's pretty often but that's fine by me. Generelly i feel that the deck needs work but doesn't yet feel where exactly. It's certainly not hopeless in anyway and though being slow it's pretty fun to play. So i hope this helps calibrating it.
