I've been trying to build a block constructed deck around Gauntlet of Power. I think the two best colors to use are either blue or red. Here's the blue list I've been working on:
Think Twice might end up becoming Whispers of the Muse, but Whispers is only good with a Gauntlet out while Think Twice is always good. I'd also like to try out Deep Sea Kraken. It's suspend cost is cheap enough that you can play it and still have mana open for counters.
2 Urza's Factory
21 Island
3 Spell Burst
4 Snapback
4 Think Twice
3 Prismatic Lens
3 Careful Consideration
4 Cancel
4 Serrated Arrows
3 Gauntlet of Power
3 Draining Whelk
3 Triskelavus
1 Spell Burst
4 Vesuvan Shapeshifter
