Oh, don't knock the Tabernacle lands. I've been using them for over 3 years now, with and without magus, they've always been nice. Against most decks armageddon + tabernacle is just as effective, you just have to make sure you play them in the correct order. I'm currently running:
//Lands
5 Plains
3 Flagstones of Trokair
1 Horizon Canopy
2 The Tabernacle at Pendrell Vale
2 City of Traitors
4 Ancient Tomb
4 Wasteland
4 Mishra's Factory
1 Savannah
//Spells
4 Trinisphere
4 Chalice of the Void
4 Crucible of the Worlds
4 Mox Diamond
4 Ghostly Prison
4 Armageddon
3 Smokestack
3 Humility
2 Oblivion Ring
2 Elspeth, Knight-Errant
//Sideboard
1 Oblivion Ring
3 Suppression Field
3 Pithing Needle
4 Choke
4 Krosan Grip
