This deck is inspired by LtsTenz great gauntlet decks :)
The idea of the deck is to run around x16 2-drop units, x12 3-drop units, and x8 4-5 drop units. All of the units are over stated (compared to vanilla units) and the deck has an excellent removal package. I feel like Banish is the best removal in the game (right now) at fast speed 3-cost and is nearly unconditional (for fast decks) with added relic removal to boot. There is an emphasis on 2-drops because of power screw in gauntlet, you need to be able to survive on 2 power for at least a few turns.
Having played the Gauntlet a lot, I will try to see if I can come up with any handy suggestions (especially for side) and let you know.
Maybe, I can at least spark a few thoughts for you.
At first glance, I can't understand why it plays Dreamsnatcher. I know it's a solid two cost card but, other than the lifesteal, it doesn't have much to offer. I feel like I'd rather have two more Vara's if nothing else. Also, the Auric Interrogator seems out of place, too. I know you could dark return him, or perhaps, blackhall him up, but, again, I feel like there are better cards? Maybe I'm wrong, as I haven't tried it yet.
