Sorcerer's Broom (Standard)

The deck wins in mainly one of two ways, but getting to that point is most of the challenge:
-Swarm with an army of powered up Sorcerer's Brooms
-Use Simic Ascendancy to win with counters from your Sorcerer's Brooms

In order to do this, a couple pieces are required:
Jiang Yanggu, Wildcrafter, Leyline of Abundance, and Sorcerer's Broom are the main building blocks.
Upon sacrificing anything, each broom in play will offer you a chance to pay 3, creating another broom.
Each broom with a +1/+1 counter can be tapped for two mana, effectively reducing the cost to 1.
The more brooms in play, the more brooms can be bought, increasing exponentially.
Wilderness reclamation allows you to use one witch's oven on your turn, and one during your opponent's turn. Or to simply enable more uses of Leyline's active ability, followed by Karn's Bastion.
Nissa, Who Shakes the World further increases the rate at which you can generate brooms and add counters.

This is mostly a deck for fun and shouldn't be expected to perform especially well, disruption of any kind can completely destroy the combo.
