I dunno man, I cant even begin to tell you how many times guard gomazoa saved my U/R deck

I would sideboard the Leylines because, they only really matter vs white and sometimes blue. I'd take out half of the shocks and unstable footings too and then add in Chandra Ablaze, a couple Pyretic Rituals, one or two furnace of Rath and then like, four Pyromancer Ascensions. In accordance with your taste
