Esper Spirits

[Desolatus]

Esper Spirits 75 cards, 15 sideboard 2 {Plains} 4 {Glacial Fortress} 2 {Moorland Haunt} 4 {Hallowed Fountain} 4 {Isolated Chapel} 4 {Drowned Catacomb} 2 {Island} 22 lands 4 {Dungeon Geists} 4 {Doomed Traveler} 4 {Drogskol Captain} 12 creatures 4 {Think Twice} 4 {Dissipate} 2 {Sorin, Lord of Innistrad} 4 {Lingering Souls} 4 {Favorable Winds} 4 {Midnight Haunting} 4 {Intangible Virtue} 26 other spells Sideboard 3 {Ultimate Price} 4 {Detention Sphere} 4 {Negate} 4 {Sever the Bloodline} 15 sideboard cards Notes: Here's my Esper Spirits deck that I'll be playing in standard for the forseeable future. I figure with Dimir and Orhzov coming in Gatecrash, this deck can only get better (and if not spirits I'll have the land base I need). Any help would be appreciated!

I'll use this for standard Cockatrice League.
