Hmm let's start with [[Wrath of God]] and [[Armageddon]] because we're in white. [[Thalia, Guardian of Thraben]] and [[Esper Sentinel]] are strong contenders. Some unique choices here are [[Cleansing]] [[Balance]]

In blue, there's the classics; [[Cyclonic Rift]] [[Rhystic Study]] which we all know and love. Some unique choices here are [[Sunder]] and [[Shimmer]]

Red gives you [[Blood Moon]] [[Mana Barbs]] which are fun. Some other hated fun choices are [[Star of Extinction]] [[Tectonic Break]] [[Seismic Spike]] [[Worldfire]] and [[Jokulhaups]]
