Not sure if any of you saw this, but vroman did a tournament report on a Landstill variant he played at the GP. It looks pretty bizarre to me, but hey what do I know, he did decently well.

He cut Brainstorm for Thirst, Counterspell for Negate, and used Chrome Mox to power out a higher than usual enchantment count. Manlands as the only win-cons. Huh? Also note he lost the mirror, facing superior card drawing and board control.
