Has anyone ever tried Impulse? I was thinking about playtesting 3 Impulse vice 3 Street Wraith. Everytime I playtest I always cut it close with the lifeloss.

So I made some changes and this is where i'm standing right now.

Artifacts
1 Black Lotus
1 Lotus Petal
1 Mox Emerald
1 Mox Jet
1 Mox Ruby
1 Mox Sapphire

Creatures
1 Psychatog
4 Quiron Dryad
3 Street Wraith

Enchantments
1 Fastbond

Insants
1 Ancestral Recall
4 Brainstorm
1 Cunning Wish
4 Force of Will
4 Gush
2 Misdirection
1 Mystical Tutor
1 Vampiric Tutor
1 Echoing Truth

Sorceries
1 Demonic Tutor
4 Duress
4 Merchant Scroll
1 Regrowth
1 Time Walk
1 Yawgmoth's Will

Land
1 Library of Alexandria
1 Island
3 Flooded Strand
2 Polluted Delta
3 Tropical Island
3 Underground Sea
1 Volcanic Island

Sideboard
2 Tormod's Crypt

2 Oxidize
2 Artifact Mutation
1 Berserk
1 Echoing Truth

Some other changes i'm considering are taking out the 3 Street Wraiths and putting in possibly 2 Mana Drains and 1 more Volcanic Island. Any thoughts?

My meta is mostly Long.dec and there has been some STAX and Manaless Ichorid decks other then that it's pretty diverse. Any thoughts on some tweaks that I should do to my list?
