So the idea struck me that voidstalker could be used as a worse-in-everyway Mangara of Corondor with all the flicker cards as worse in everyway Karakass or flickerwisps.

So I put this together. It's basically tempo, apart from the voidstalker trick, you flicker creatures around to stop anything happening to them with Cloudshift, Ghostly Flicker, and Restoration Angel. Mess up your opponents creature base with Unsummon, Fiend Hunter, Oblivion Ring, and use Witchbane Orb to stop anything straight to your face or stuff that makes you sacrifice creatures (to get around being able to flicker stuff). To win just do it the old fashion way swinging with those decent sized angels.

It's all post rotation.

The Void Stalker trick: use it's ability and then flicker it, it then returns to the field while the other creatures gets sent to the other players library. hooray for reusable blue removal.
