U/R Gifts Storm (Modern)

An explanation on lands:
I'm not running Scalding Tarn as a fetch land. Due to cost.. If you own them, please rebuild your mana base!

90% of the time Scalding Tarn sacrifices for Steam Vents untapped. This is 3 damage. As we are hoping to go off turn 3 if possible, I am attempting to justify painlands instead. By turn 3, the most a pain land can hurt you is also 3 damage. However, leaving Mana up for a Remand and not needing to play it saves us the shock damage of getting an untapped Steam Vents. In this case we have not lost any speed in our lands, and we have possibly saved life. The drawbacks show up later in the game turn 4 or 5 against heavy control, and from not thinning our deck. If deck thinking is troublesome we can remove a City of Brass for an additional Thought Scour bringing us to only 17 lands. Running only 2 Sulfur Falls gives us a chance to get an Island/Mountain/Steam Vents out first. Without the fetch land giving us "12" Islands/Mountains and only 8(1/3 less) I cut Sulfur Falls from 3 -> 2 (1/3 less).

All of this said, I understand I'm not running the best land base.

Suggested Land Base:
4 Scalding Tarn
4 Steam Vents
3 Sulfur Falls
3 Shivan Reef
2 Island
2 Mountain
