mtg imperium commander deck MTG: Warhammer 40,000 (40K) Decks Collector Edition MTG Warhammer 40k Commander Deck:

It's an instant, 4-mana Desert Twister that exiles

Wonderscape Sage Most of the Moonfolk required a mana investment to return a land from the battlefield to your hand for a special effect, such as Meloku the Clouded Mirror

Zuran Orb combined with Armageddon or opposed land destruction to flat out give you a giant life swing on cards already headed for the graveyard, and Balance and Land Tax are even better

He was so powerful that in one tournament, every single one of the top 8 decks was running 4 copies of him, almost unheard of in Standard.

Normally you can only cast non-sorcery spells during your main phases
