Alright so I have been playing around in modern coming up with some brews and not just regular brews crazy ones like modern dredge and I know I should have posted this in the modern forum but I just wanted everyones help with this deck
Here is the list
CREATURES 20
4  {Deathrite Shaman}
4 {Golgari Thug}
3 {Phantasmagorian}
2 {Simic sky swallower}
4 {Stinkweed imp}
3 {Street wraith}
SPELLS 21
4 {Dangerous Wager}
3 {Explore}
4 {Faithless looting}
4 {Gitaxian Probe}
3 {Life from the loam}
3 {Unburiable rites}
LANDS 19
1 {Blood Crypt}
4 {City of brass}
1 {Dakmor salvage}
4 {Gemstone mine}
3 {Horizon canopy}
3 {Stomping ground}
3 {Verdant Catacombs}
Notes on maindeck: originally I had   {Griselbrand} has my reanimate target but I kept getting blown out by removal so I switched to  {Simic Sky Swallower} because of its shroud if anybody knows of any other better bombs let me know I have been thinking  {Avacyn, Angel of Hope} is probably just way better. The  {Explore} is actually very good it lets my deck go off a turn sooner and it has good synergy with  {Life from the Loam} because it lets me draw a card so it can alsp activate all my other dredgers.
SIDEBOARD
4 {Leyline of sanctity} so i dont get blown out by sacrifice a.k.a  {Liliana of the Veil}
4 {Nature's Claim} for {Rest in peace}
3 {Bojuka bog} for other graveyard decks
4 {Lingering souls} for the aggro decks

So what I need the most help with is an answer to {Deathrite Shaman} that card just destroys me is there any card anyone can think of that just beats {Deathrite Shaman} times like these where I wish {Ground Seal} just gave my graveyard hexproof

 {Iona, Shield of Emeria} is a good bomb too. Don't play this card with your friends please!
