This started to be an experimental deck, but somehow turned into a real decent Gauntlet grinder.
With Unleash hitting Eternal, i have been testing a lot and this is actually some sort of a broken combo i came across, yet it has still a lot of space to improve, since the deck is not optimized.
What we are looking at is:
Valley Whisperer +
Xenan Obelisk +
Sand Warrior
(it must not be Obelisk, it can be anything that gives atleast +1 atk when hitting the board).
What it does is, it keeps
Sand Warrior at 0 cost, since its still technically 3/3, yet it triggers Unleash when hitting the board, because it turns into a 4/4 (or 5/5)
The best start:
Turn1: +1 Maximum power + power
Turn2:
Auralian Merchant + power (grab Obelisk)
Turn3:
Xenan Obelisk + power + whatever
Turn4:
Valley Whisperer +
Sand Warrior
Turn5: gg
Obviously the above mentioned would be perfect starter hand or perfect draw, but even if that doesnt happen, the deck will outperform almost every AI deck in midgame and can even pose a big threat in late game.

In the screen above you can see, that the Unleashed copy of
Sand Warrior is still at 0 Cost when getting popped into your hand. This is because the Unleash is getting triggered by
Valley Whisperer and since
Sand Warrior (in your Hand) will still be a 3/3, it will not get targetted by
Valley Whisperer, thus will also not be affected by the normal unleashed minimum cost of 1.
Yet the Copy that is ON the board will show cost of 1, because it is above 3 atk and therefore counts a target for VW.
(my max power is reducing because i'm sacrificing some mana dorks to show a almost full board of Sand Warriors without them cost anything)
A few thoughts after trying this out:
Whisperer should probably be in the market? That way you have 8 ways to access it, you don't need more than 1, and it's explosive enough that paying for the merchant is fine.
Alhed Ascending belongs here. It's bonkers when unleashed, attacks for the win right away when you go off with Sand Warrior, and is just good.
Sandstorm Titan. You're playing time in gauntlet.
Dawnwalker is also fun with Whisperer. Every trigger doubles your Dawnwalkers, though you would need to jam some more 5+ atk units to trigger it. Alhed and Titan count, and you could also consider Prism Golem, Moonstone Vanguard, Krogar, and even Snapping Hydrangea (which is a good unleash target).
Overall, this would take the deck in a more midrange direction with a combo option, which is usually a good recipe for gauntlet in my opinion.
Edit: Another thought - Journey Guide would let you go infinite with units other than Sand Warrior, including Alhed (with <6 influence) and Restorationist. That might be a better direction than the Dawnwalker package.
