Oops, All Spells! (Formerly The Rogue Hermit)

[slave]

I've been goldfishing a sideboard that looks like this:
4x Dark Depths
4x Thespian's Stage
4x Sylvan Scrying
3x Spoils of the Vault

I'm wondering whether replacing Scrying with Crop Rotation might yield better results.

Crop Rotation is a much better card of course, and it was my first thought ahead of Sylvan Scrying, but since we're a No-land deck I'm assuming it's not worth pursuing.
I've been proven wrong plenty of times before though.

I guess this really goes back to whether we run a main to accommodate, IE Land Grant x4, and a single Bayou.
