MTG Salvation

Im not( im after this players list as well , if you get it please share here );

Im fairly experienced with the deck and i found that the cmc 2 answers to the GY hate cards slow me down to much, specially when the ones playing those are other fast decks. thats why im hovering to the white splash ( which gives me acess to both Wispmare and Ingot chewer ) or the standard Jund version with some nature's claim.
I think speed is the name of the game.

This is my SB today :


My LGS is full of burn so i sb heavily to crush them . For the Gp i will swap some cards around to fit 2 more anti-hate cards and the leylines of the void ( wich im also considering playing main deck ).
Driven // Despair is a really neat trick against decks with no blockers like tron and phoenix as its fairly easy to mind twist them.

Im going to play in a Magic Fest very soon with this deck and I have been toying with some ideas to improve on both the decks consistency and post board gameplans.
Have any of you guys had any experience with :

• Flamekin harbinger as a pseudo-entomb card for vengevine? Had this idea looking at some old builds.
• Ghor-clan rampager as a way to push some damage specially in post board games which are very often scrappy because of Gy hate.
• Hazoret the fervent out of the sideboard as a creature that doesnt need the GY to work and can win the game on its own against slower decks.
