Root Cause
Nature is fighting back, and it's using weapons of moss destruction!
Root Cause is a Black/Green deck that uses the synergy of Treefolk, Fungi and Saprolings to create tokens, bolster its creatures and eventually overrun the opponent with an all organic beatdown!
A fast Black-Green deck that applies immediate pressure using aggressive early plays like Lash of the Balrog and Deathspore Thallid and aims to close games before opponents can stabilize.

Game Plan
Early Game
Turns 1-2
Deploy Lash of the Balrog and Deathspore Thallid as early as possible and commit to attacking. Every turn you don't attack, you fall behind on your plan.
?
Mid Game
Turns 3-4
Maintain pressure while watching for open attacks. Use your interaction to clear blockers rather than save it for defensive purposes.
Late Game
Turn 5+
With most of your hand played out, aim to finish the game before topdecking. Prioritize evasive threats.
