{Eternal Witness}/ {Archaeomancer}
{Ghostly Flicker}
{Sphinx-Bone Wand}
{Gilded Lotus}
Use lotus to add 3 {U} mana to pool, use {Ghostly Flicker} to flicker {Eternal Witness} or {Archaeomancer} and {Gilded Lotus}. Use witness/Mancer to bring back {Ghostly Flicker}. Repeat while {Sphinx-Bone Wand} collects counters and shoots your opponent.
Add {Inexorable Tide} to speed things up. =D
Kind of mana costly, I would say {Gilder Bairn}, {Training Grounds}, {Paradise Mantle}, {Shrine of Burning Rage}. All you need is 4mana max
