I would recommend Wheel of Fortune for card draw if you happen to run out of gas.

Enral, I wish that I could run it. However, I have no plans of changing either general out. So the only Wheel of Fortune type cards I can run would be Windfall (and hope that someone has more cards), Diminishing Returns, Time Reversal, Time Spiral, or (if I had no budget) Timetwister.

I feel like Bloom Tender isn't the best in this deck since I only have 2 colors. It needs to be able to tap for at least 3 to be a part of any infinite combos that I have. Also, on turn 2 I can start searching for combo pieces using a combination of hand sculpting cards and shuffle effects from ramp spells, or get Thrasios, Triton Hero out to be ready to combo. I am not really running any creatures that would need haste other than Kydele since everything needs to be ready to use the same turn I combo out, or it is useless in the deck.

On that note, I might be removing Hedron Crab in favor of another combo card like Future Sight or Mind Over Matter. The only concern I have is the amount of required to cast those spells. Hedron Crab only matters when I'm dumping all of my lands out onto the battlefield with infinite mana. Ambassador Laquatus already serves this function perfectly.
