Voice of the Bloody Junk (Standard)

Since I play MTG, I really love to sac creatures for evasion or value. With " Voice of the Bloody Junk" I tried to create a deck which is able to do that AND still got the classic midrange or aggro theme.
I want to write a little bit about some cards:
First of the Voice, I'm not one of the players who says "damn this card is sooooo awesome!! I want to splash white or green in every single deck!", I think the Voice will be veeeeeeeeeeeery good in the beginning of the meta, but just like boros reckoner the meta will learn to deal with it. So you have to find a way to get the power of this card on your own. Dont think your enemy will cast a eot think twice to give you a token.
Next up is the High Priest:
I put him in to the deck because you can have the OLOLOLOL start with: t1 doom travler, t2 High priest, t3 aristocrat = 5/5 demon. But the more realistic reason is, he can still make 5/5 flyer in turn 4<, which is still good.
Now the Varolz:
I just want to try him out.
Sorin:
Just some additional reach for such a cc2 heavy deck. His +1 can do some stuff with blood artist, skirsdag, aristocrat or even Varolz. We need to get the opponent to 0, that's why his -2 is also good. I never activated his ultimate.
Now the sideboard, first of the Ground Seal:
I don't like cards like Rest in Peace in this deck and I need to shut down the whole grave of my opponent, I also like to draw a card to get maybe some action after I shut down his grave.
Shitte... sorry Gideon:
I don't like him, he don't likes me, but I got stomped by a one-of with a slower deck. I think against some decks he can be a real pain in the ass for them.
Sin Collector:
Supreme Verdict, Revelation, Rites, Azorius Charm, XXX Counter Spell, any questions?
Unflinching Courage:
Maybe a little bit to slow, but a good card to race some decks, trample is also very good against lingering souls.
If you have any questions, write them down so I can see them!
I don't think anyone will read that far so:
