[Standard] Newbie here, MTGO Need advice on my Ally/Vampire deck

http://deckstats.net/decks/43486/429852-standard-vamp-ally

This is for casual just for fun games, at least for now, as I'm really new and wanted something pretty cheap.

I've played it three times and all three times I've been short the mana I needed at the beginning of the game or getting stuck with just white mana when I need at least one black-or vice versa- (bad luck perhaps).

Are there any cheap lands I'm missing that I could pick up, or other cheap cards I may be overlooking? Would Evolving Wilds help?

Should I just drop Blighted Steppe and put two more basic lands or evolving wilds??

Are there cheap cards I'm overlooking?

Ally Encampment has been my saving grace so far to get at least a few creatures in play.

Thanks in advance!
