Lots of curve friendly ramp that has many outs in lots of scenarios. The deck essentially wants to go, ideally, 1 drop elf, 3 drop, then a five drop dragon on turn 3. If it missed a mana elf turn one, then things like Atarka's Command into Thunderbreak Regent on the following turn can work really nicely. Even if not used to ramp, Atarka's Command is still a very flexible card, and will most likely always have a use. Or even turn one mana elf into Rhythm of the Wild turn 2 is a solid play. Lots of options of how to curve out your turns. One important thing to point out is that the deck lost a whole lot of consistency with the Once Upon a Time ban. I've been trying to figure out how to iron this out since the ban, since with OUAT, the deck was incredibly streamlined and to the point. The deck also starts to run into problems against turn 1 or 2 removal, if they take away your mana elves, or even your 3 drop planeswalkers. These removals hurt a lot, and slow down the deck substantially.
Essentially, if the deck can get dragons out and hitting your opponent from turn 3, then you're in a great position, but it you have a slower start with Rhythm of the Wild instead, then it's poised so that all your turns after that are very solid, and hit very hard. Rhythm of the wild gives the potential to drop an Atarka World Render, and start swinging with the board wide double strike right away. Or Dragonlord Atarka even benefits from Rhythm of the Wild with his fantastic stat line and keywords for a 7 drop. Thunderbreak Regent can also enjoy a nice haste buff, or dragons that are already hasty such as Glorygbringer or Stormbreath Dragon can benefit from an additional +1/+1.
Let me know what you think, or if you have any suggestions for what to include! Keeping in mind the sideboard is a rough sketch at the moment, and should probably include some more ways of protecting board state in the early turns. (Rip Veil of Summer)
