Something I've been messing with:

4 x AEther Vial
3 x Bonesplitter
3 x Mox Opal
2 x Tidehollow Sculler
1 x Phyrexian Revoker
1 x Umezawa's Jitte
1 x Sword of Fire and Ice
1 x Ethersworn Canonist

Black:
4 x Dark Confidant
2 x Night's Whisper

White:
4 x Puresteel Paladin
4 x Swords to Plowshares
3 x Kor Duelist
3 x Stoneforge Mystic
2 x Enlightened Tutor

Land:
4 x Ancient Den
4 x Marsh Flats
4 x Scrubland
3 x Plains
1 x Swamp
1 x Vault of Whispers
1 x Arid Mesa

Sideboard:
1 x Ensnaring Bridge
1 x Pithing Needle
1 x Sword of Body and Mind
1 x Enlightened Tutor
1 x Humility
1 x Runed Halo
2 x Engineered Plague
3 x Perish
4 x Seal of Cleansing

I've liked vial, but generally found that using vial required the use of extensive card advantage engines (bob, etc).Vault Skirge has been absolutely amazing in testing, as has Kor Duelist. Cranial plating probably needs to go in here, as well as batterskull, but this is a pretty rough list atm. Also one of the sculler's should probably be the 4th SFM. And I might potentially go to 1 maindeck e-tutor with 2 in the board.

I think generally everyone here is missing the boat on Enlightened tutor as well - the versatility is amazing and it's randomly a mana fixer as well - and it's sideboard applications really shore up many of the toughest matches for the deck.

So far my biggest fear has been Null Rod, which is why I'm running the disenchant's (seal's) in the board. I'm curious if anyone has tested their decks against anything other than merfolk?
