Was working on UG Green Tide with Dictate instead of Heartbeat, then tried to force it to be Solidarity, and then my friend suggested I steal from the BUG Mystical Teachings/Wilderness deck. So what we end up with is a Mystical toolbox/control shell that ramps up to an EOT Dictate and then combos into a lethal USZ. Being entirely instant speed means that 1) everything can be found by Teachings and 2) you can combo off at any time.

Reality Spasm is better in almost every way than Early Harvest. Early Harvest is better mana, but Spasm is even at 2 lands and net gain after that. And it can be used defensively if you need to tap down your opponent's lands before going off, or stall a board of attackers. It can also untap your nonbasics and even your Snapcasters in case there's ever a niche case where that's relevant.
