With Delver, Pyro, and Mentor pushing the creature wars back into Vintage, Punishing Fire/Grove of the Burnwillows seems strong.  Needlebite, while underrated, is strong and hilarious against storm.

Here is the list I am tinkering with:

1 Ancestral Recall
1 Cabal Ritual
1 Brainstorm
1 Chain of Vapor
1 Hurkyl's Recall
1 Mystical Tutor
1 Vampiric Tutor
1 Demonic Tutor
1 Intuition
1 Imperial Seal
1 Mind's Desire
1 Ponder
1 Preordain
1 Time Walk
1 Timetwister
1 Tinker
1 Wheel of Fortune
1 Windfall
1 Yawgmoth's Will
4 Duress
2 Gitaxian Probe
2 Needlebite Trap
1 Memory Jar
1 Sol Ring
1 Regrowth
1 Yawgmoth's Bargain
2 Jace, the Mind Sculptor
2 Punishing Fire
1 Black Lotus
1 Lotus Petal
1 Mana Crypt
1 Mana Vault
1 Mox Emerald
1 Mox Jet
1 Mox Pearl
1 Mox Ruby
1 Mox Sapphire
1 Mox Opal
1 Blightsteel Colossus
4 Grove of the Burnwillows
3 Scalding Tarn
2 Underground Sea
1 Volcanic Island
1 Tropical Island
1 Mountain
1 Tolarian Academy
1 Library of Alexandria

Sideboard:
3 Grafdigger's Cage
1 Tasigur, the Golden Fang
1 Ingot Chewer
1 Dack Fayden
1 Hurkyl's Recall
1 Rebuild
1 Crucible of Worlds
1 Thoughtseize
1 Steel Hellkite
1 Runeflare Trap
2 Red Elemental Blast
1 Strip Mine

I want at least one Nature's Claim somewhere in the maindeck, and maybe a Nether Shadow for Intuition.

The sideboard is a hodgepodge of ideas to see what works and what doesn't.
