Overwhelming Skyline

HOO BOY. With a bit of support these unleash cards really go off.
Key cards
The Unleashers: Barbarian Guerillas, Carnivorous Terror, and Striding Skyline
And given the key word they all share... Shepherd's Horn. Makes them cheaper and gains nonsense amounts of life, giving you enough time to go off, and is a relic for the Nonsense Skyline
And the obvious inclusion: Journey Guide - he's in every Unleash deck and is excellent here as well.

Just that core is enough for a pretty strong deck. When the unleash cards go off, they go off so, so hard.

A few other card choice notes of worth:
- Logistics Expert - really improved the deck. Forgot she had Overwhelm! Is weirdly often worth it to wait and cast the turn after Shepherd's Horn to get the life and the 4/5
- Vicious Overgrowth - went from "does this work...?" to "Oh shit, boy does it ever!" - Shepherd's Horn says "Your cards with Overwhelm" not "unit" - which means this is often a 1-cost deal 3, gain 3. Which is, uh, worth it, lol
- Sandstorm Titan - Deck is pretty weak to fast flyer draws and you don't want to get run over. So put up a wall
- Valley Spring - Mostly too slow, but can be strong to grab just before the turn you go off as it helps make every subsequent unleash cheaper

It's early, probably still lots to improve, but it's also a really enjoyable deck for some nonsense!
