Well Wasteland only casts Tarmogoyf in RUG Delver and their mana denial plan wins a lot of games for them. Wasteland is valuable in this deck, yes it only casts pyro but that's fine.
I haven't sleeved it up yet, as I am deciding between this deck or ANT for the Legacy GP in November but if I did it would look something like this:
Creatures (12)
4x Monastery Swiftspear
4x Delver of Secrets
4x Young Pyromancer
Sorceries (11)
4x Gitaxian Probe
4x Ponder
3x Treasure Cruise
Instants (20)
4x Lightning Bolt
4x Brainstorm
4x Stifle
4x Daze
4x Force of Will
Lands (17)
4x Scalding Tarn
4x Flooded Strand
4x Volcanic Island
1x Island
4x Wasteland
This would be my shell. Would have to experiment on whether you want an 18th land or go down to 16, whether you want the 4th cruise, if you want spell snare or spell pierce in the mb, maybe a chain lightning or forked bolt, even some preordain, etc.
