You need to be running Vampiric Tutor .
I would strongly advise not to run Mana Flare . Some decks (i.e. your elf deck) would probably benefit way more than what your deck would--and would most likely get you too far behind. Without green especially, I would highly not recommend not run a worldwide mana accel.
Also, I might consider Oracle of Mul Daya . Finally, you need to go to at least 36 lands, I might push 37-38.
