This deck is so fun with the addition of Plaguemaw the Rotting and its synergy with Greybough is insane. Moreover, you can have maximum 5 N'Zoths if you utilize Elise the Enlightened. I recommend Fizzy Elemental over Scrapyard Colossus because it has both Rush and Taunt, and can be resurrected by both N'Zoth, God of the Deep and Hadronox.
I hope you guys have fun with this one. If you have any questions, pm me or leave a comment. Thank you for reading.
