I've come up with a deck that I thought might be fun, it is based around the idea of indirectly killing your enemy through the abilites of creatures like
blood artist 
,
guttersnipe 
and
deathrite shaman 
; I originally tried to make this into a discard burn deck but found it worked better as more of a direct burn deck, tell me what you guys think.

I think this deck will work with 19 lands because the mana curve is 3, when ive tested it, it seemed to work fine; I put 2
woodland cemetery 
s into the deck so I could use
deathrite shaman 's life gaining ability, also helps against undying I suppose, considering putting in 2 more
woodland cemetery s.
