Originally this was supposed to be just about Land Destruction in Standard but I tweaked it to the point that it has a little bit of everything.
Between your ramp to Tamiyo or Nicol Bolas and the land destruction from Bramblecrush and Acidic Slime/Cloudshift your opponents will be on their toes as to what to try to defeat first.
You can also control the game from Dungeon Geists/Restoration Angels/Cloudshift/Snapcaster Mage abuse.
Once Omniscience becomes legal you can go "infinite" with tamiyo ultimate. Play free slime (destroy a land) ---> play free cloudshift target your slime ----> target their land on reentry or just play free Bramblecrush. Or just add in a sideboard that allows you to do whatever crazy stuff you want. (If you can use Tamiyo ult in Miracles why not here?)
