Mirko Vosk Cap

This is a mill deck. The "Jester's Cap" (exile from library) effects are for removing lands from the opponent's deck, so Mirko Vosk's "Grind" effect does more. Of course, old Eldrazi titans and other reshuffle effects should be hit as well.
• Leyline of the Void effects
• A few ways to make Mirko Vosk unblockable
• Copy Mirko Vosk (Helm of the Host, Sakashima, Spark Double)
I considered some extra turns effects (for more attacks), but people hate that, so I decided against it.
As of this writing, Mirko hasn't been errated to use the term "mill". (I don't expect it use "mill" due to the way it works.) So it doesn't double with Bruvac the Grandiloquent.
