Your mana curve is way too high for modern. You're going to lose a lot of games with a bunch of four and five drops stuck in your hand. You also don't really have a cohesive strategy. I would would consider either a more controlling shell (and you could use
Sanguine Bond/
Exquisite Blood combo for a win con), or moving to a more aggressive shell similar to a
Martyr of Sands build.
Either way, I would highly consider adding some lands that generate both colours of mana, such as
Concealed Courtyard,
Isolated Chapel,
Caves of Koilos, or
Temple of Silence. Or just bite the bullet and get your copies of
Godless Shrine while they're still being printed for standard.
