UWR- Blink in Std

I stopped playing magic right before the release of Kamigawa block after having played for about 3 years. I went through periods where I would play a FNM events every couple months, but I never really got serious about the whole process as I had in the past. Anyway, I decided I might give magic another try with the release of Lorwyn. I built this deck for standard.

Mana Base: 22
4x Shimmering Grotto
1x Island
2x Plains
2x Mountain
4x Battlefield Forge
4x Adarkar Wastes
1x Gemstone Mine
4x Terramorphic Expanse

Beat sticks: 11
3x Akroma, Angel of Fury
4x Lightning Angel
4x Keldon Marauders

Utility Spells: 13
3x Inner-Flame Acolyte (creature)
3x Mulldrifter (creature)
4x Momentary Blink
3x Heat Shimmer

Disruption: 14
3x Rune Snag
4x Delay
2x Wrath of God
4x Oblivion Ring
1x Disintegrate

Anyway, I'm really pleased with this deck. It was originally based around galepowder mage/ avalanche riders, but this proved too slow on apprentice testing. I've found that when I start with Keldon Marauders in hand I tended to win. One thing I really like is that this build has a lower mana curve than other builds I've seen. I don't run Venser (I have trouble getting 2 sources of blue). Instead, I've opted to include cards like rune snag and oblivion ring. I'm curious to see what you think.

SB: Maybe...
2x WoG
3x Lash out/ Incinerate
4x Condemn
4x Pithing Needles
2x ?
