DailyMTG: Sealed Deck Builder!

Well, it has been a while, but anyway... I've become increasingly interested in Sealed and Draft, so for the fun of it, and to test out my deck-building skills, I tried out the Sealed Deck Builder on Daily MTG.

Here's what I came up with:
Land (18)
9 Mountain
9 Plains

Creatures (16)
1 Angelic Skirmisher
2 Court Street Denizen
3 Daring Skyjek
2 Ember Beast
1 Firefist Striker
1 Foundry Street Denizen
1 Nav Squad Commandos
1 Skinbrand Goblin
1 Skyknight Legionnaire
1 Spark Trooper
1 Towering Thunderfist
1 Wojek Halberdiers

Other Spells (6)
1 Act of Treason
1 Angelic Edict
1 Holy Mantle
1 Madcap Skills
1 Mugging
1 Skullcrack

I like this card more than I probably should...

As far as I could see, Black was absolute junk, and Blue didn't fare a whole lot better in general. I was sold on White and Red as soon as I saw Angelic Skirmisher, Wojek Halbediers and Spark Trooper all in there, not to mention all the other Battalion guys and generally good cards.

I'm a bit disappointed in the lack of one-drops, but then there wasn't really any in the entire pool except Experiment One and Spire Tracer (and Foundry Street Denizen, both of which are decent enough (in fact, I run Experiment One as a 4-of in my Constructed deck...), but not worth messing around with the mana base for, especially with only one dual land available in the right colours (and one that enters tapped at that). Besides, it's 2 cards and if I don't get them first turn, along with a Forest, they're a complete waste, and that also shuts down any chances of a turn 2 Wojek Halberdiers, so I decided splashing for green just wasn't worth it, not even for the other RG cards available. Not when there were so many good cards in just White and Red, anyway.

So I'm interested in hearing your thoughts. I'm pretty new to building Sealed decks honestly. The last time (and first) I did it was at the Gatecrash Pre-release, but I'm getting there. Feel free to post up your results in the comments as well!
