I went 5-0-3 at a small event today playing UBwg Doomsday. I played the same maindeck I'm playing in the mtgsalvation tourney -1 Volcanic Island, -1 Badlands, +1 Island, +1 Plains. My sideboard was mostly standard with the notable exception of 1 Infernal Tutor, 1 Ill-Gotten Gains in my sideboard against heavy discard or aggro. As it turns out, I played against a lot of combo decks in a rather undeveloped metagame. I beat UB Helm of Obedience Combo-Control, WR Enchantment Solutions w/Painter Kill (I think) twice, BR Spanish Inquisition, and Uwr Landstill/Scepter Chant w/CB+Runed Halo+Scepter via Enlightened Tutor Toolbox between swiss and top8. I.D.'d against UGb Survival Painter and Affinity in swiss and against UGb Survival Painter again in the finals.
