UB Trinket Mage deck, only with Tezzeret. I've never built a UB Control deck before, and I haven't been looking at many versions of the deck.
I like where you're going with this, but I feel like it needs more win conditions and removal - go for wurmcoil/ more effigies / chimeric masses. sideboard 2 rebuttals, switch a chalice and a mimic vat for 2 wurmcoils, add 2 effigies. a nice start though.
