While reading through the topics posted at the Spikes subreddit, I came upon a tournament report of a person playing UR Dynavolt in their Gameday and which he faced a kid piloting a mono-Green aggro deck. The card composition according to the way his match went were Blistering Hydras, Servant of the Conduit, Tireless Tracker, and coupled with pump spells like Larger than Life. He posted an assumed decklist but I decided to refine it a bit.
