This deck is pretty incredible. I have not been deck tracking this, but out of approximately 50 games on ladder with no star bonuses I went 47-3. I am not sure it'd have this type of success at higher ranks, but I still wanted to acknowledge how much better this deck has gotten over time. You can swarm the board over and over again, most the time your opponent just can't stabilize. Tour Guide and Righteous Cause can win you a game by turn 4. There are some Mech synergies that work nicely together, but aren't dependent on each other.
The two Fungalmancer feel like they can be swapped out. If anyone has any recommendations to refine this further, I would love to listen to suggestions.
