The Alliances deck just seems really weak. How about a Browse/Digger deck, something like this:

4 Force of Will
4 Arcane Denial
4 Browse
4 Lat-Nam's Legacy
4 Exile
3 Reprisal
1 Errand of Duty (possible kill card with Digger/Browse)
2 Soldevi Digger
3 Spiny Starfish (Bad, I know, but you need a steady blocker)
3 Lodestone Bauble/Foresight

4 Thawing Glaciers
3 Kjeldoran Outpost (main kill card)
1 Soldevi Excavations
11 Island
9 Plains

Plan of the deck is to thin the deck out by Thawing out lands and Browsing until you have a Digger and an empty library. Then you just recycle whatever you need (counters, Errand, Reprisal) for the kill.

That would be a good name, except it was just used in Darksteel.

I think the "rules-making" cards like this are a good direction for white to go in.
