Looking for some constructive criticism. I've played roughly 40 games with this deck and I believe the dedicated combo version is the best plan. Trying to go aggressive with unblockable creatures just doesn't work against other high tier decks, especially since this isn't Voltron. The basic gameplan is to drop Ezuri as quickly as possible and fill up the board with value creatures while at the same time progressing towards five experience counters. Countermagic and general disruption provide protection for Ezuri and the turn you go off with Sage of Hours. This deck is actually very consistent at assembling the combo, but it's reliant on countermagic to successfully win. However, this isn't exactly a downside since you're UG and have access to a decent amount of disruption.
