Since you can afford to buy a playset of Stoneforge Mystics, might I recommended replacing the Mystic for Enlightened Tutor. The tutor is at least 1 turn faster than the Mystic and you can pull the Mantra if need be. I would also recommend 2 Test of Endurance(don't need more if you are tutoring) as an alternate win condition.
Here is the soldier deck that we came up with a while back(never built it). You can draw ideas from it. Also I would take out the *** type cards, because you don't want to bomb your own villages.
I would cut Imp's Mischief for another Doomblade and maybe some Sinkholes if you can afford them. If not, Rain of Tears should replace the res of the Imp's Mischief.
My name is Arthur, so I would like to select the sword for this deck if your cool with it. I think this deck should be kept Black/White. Also, the Black Night should be Haakon, Stromgald Scourge

I would use Blackcleave Cliffs instead of Lavaclaw Reaches because it has a chance to come into play untappped. Same goes for Raging Ravine. Copperline Gorge is better unless you really want and plan on using those manlands. I would add in Overwhelming Stampede/Overrun as a finisher.
