Looking at the Cabaretti Legends between 'Outlaws of Thunder Junction' and the 'Desert Bloom' commander deck, there's a few I'm looking forward to playing. To be honest though, where Yuma and Annie are concerned, they are highly costed. May be a little too much. although they both have considerable power/toughness.
And no matter how much I love the character of Yuma, he costs 8 mana if you don't have any lands in your graveyard. Though I do love his abilities as they go well with both Kirri and Hazezon.
Yes, Hazezon, Shaper of Sand is reprinted in the 'Desert Bloom' commander deck with new boy Kirri, Talented Sprout. So you can have Sand Warriors along with Plant creatures. And just in case you don't want to do just a Plant-based deck, Kirri also works with Treefolk ...for some reason. Personally, just for quicker play, I'd run these two instead of Yuma and Annie.
But that's not all. We can't forget about Ghired or Bristly Bill. Ghired gives your nontoken creatures the ability to make token copies of creatures that enter the battlefield on each turn and Bristly Bill gives +1/+1 counters on landfall triggers.
As I've said, I'd rather play my Abzan colors but I do like these options and the 'Desert Bloom' deck looks exciting.
