sideboard plan mythic: [ -3 elspeth, -2 consuming vapors] [ +3 thought hemorrhage, +2 path to exile] pyromancers ascension: [ -3 elspeth, -4 consuming vapors, -1 linvala, -4 cunning sparkmage, -1 gideon jura] [ +3 thought hemorrhage, +4 leyline of sanctity, +4 leyline of the void, +2 luminarch ascension] naya shaman: [ -4 tidehollow sculler] [ +4 leyline of the void] titan valakut ramp: [ -2 gideon jura, -1 linvala, -3 oblivion ring, -1 elspeth] [ +4 leyline of sanctity, +3 thought hemorrhage] u w control: [ -4 abyssal persecutor, -1 linvala] [ +3 thought hemorrhage, +2 luminarch ascension ] main benefits: seems to have answers to the main deck imo. it has multiple threats that cant all be dealt with at once and has a good game 2 matchup to most decks. main downfall: bad mana base. i need help with it, i think if i can get the mana to work this might be a decent midrange control deck. i have not playtested this!!!!!
