Path to Exile your Deck

the idea is to play a big mill spell like mind funeral or archive trap (or even when beleren blows for -20) and then drop a bojuka bog thats been held in hand to exile all the milled cards. now, this may not matter against some decks, however, many decks have ways of drawing cards back from the graveyard (or at least unearthing them for some major damage). so, against white decks running marshals anthem, black decks running grim discovery or bloodghast, green decks running natures spiral and rdw running hellspark the bog is a must! also, as you can see the sideboard is control. there are reasons for this... ) suggestions and inquiries are much appreciated!
