UBw artifact deck made to abuse blink effects for Bleak Coven Vampires and Mulldrifter. Ghostly flicker can also target lands and artifacts creating interesting plays against the meta. It is performing very well in Pauper Casual on MTGO. Looking to take it to tournament practice but looking for advice first.

Arguments can be made to eliminate the trinket mages for sea-gate oracles but this deck is very mana intensive. Plus, the trinket mage will be finding additional artifacts for gearseeker serpent. Any advice is appreciated.
