A lot like the Fires of Yavimaya deck in Mercadian Masques/Invasion Standard of long ago, this is a / aggro midrange deck. (Moment of silence for Saproling Burst.) Since that deck was the inspiration for this one, I've put in a playset of Untamed Kavu as an homage to Kavu Titan.
The only requirements to meet the archetype are 4 Llanowar Elves, 4 Elvish Mystics, & 4 Rhythm of the Wild. This makes the deck ¾ flex slots, so the deck is filled out with a cocktail of fatties & burn to taste.
This particular version is only running a playset of Steel Leaf Champions as an alternate 3-drop, & a pile of fun-ofs just to mess with our opponents (and because I'm always mucking about with this deck so I don't know exactly what creatures I want in here).
Mana base is a little shaky since you need to be able to afford or on turn 3.
As much as we really power up with it, there's only a 48.7% chance of seeing at least 1 Rhythm of the Wild in your first 9 cards. (Thank you, https://stattrek.com/online-calculator/hypergeometric.aspx for the slightly disenheartening math).
I've made a pretty generic sideboard which can be used in most metas.
Magical Christmas Land:
Turn 1: Llanowar Elves or Elvish Mystic.
Turn 2: Rhythm of the Wild.
Turn 3: Something big & attack with it.
Turn 4: Another something big & attack with it.
Turn 5: Yet another something big & attack with it.
Turn 6: One more something big & attack with it.
Victory!
EDIT: This deck is now officially in flux since I'm going to be tinkering with it for awhile. Comments, ideas, & suggestions are, as always, welcomed.
