Hey guys, i am, obviously new here, but i've been out of vintage for a while.

Im a large fan of prosperous bloom, and would like to take it to a vintage tourney thats near me next month. There wont be a lot of power players, so i think the deck would be viable to compete. Heres the "modified" decklist that ive got so far, any help would be appreciated.

Land:

4 Gemstone Mine
4 City of Brass
6 Island
5 Swamp
4 forest

Mana Acceleration:

4 Squandered Resources
3 Natural Balance
1 Sol Ring

Engine:

1 Soothsaying
1 Mystical Tutor
1 Enlightened Tutor
1 Vampiric Tutor
1 Demonic Tutor
1 Yawgmoth's Bargain
3 Prosperity
2 Meditate
4 Infernal Contract
4 Impulse

Control:

2 Arcane Denial
2 City of Solitude

Kill:

4 Cadaverous Bloom
2 Drain Life


Anyone have any ideas ? i know the deck can be better than this, but so far its all i can think of.
