Made some changes! Crater's Claws had become dead weight thanks to the inclusion of Lightning Bolt and Thunderous Wrath earlier, and I added two Roasts to the sideboard in the event of Big Scary Things. Arlinn Kord
Flip is great but I often wound up having one in my hand when I either couldn't or didn't need to cast it, so I removed one.
Mainly, I needed more creatures. Courser of Kruphix can help with card advantage. Boon Satyr is a fairly efficient creature that hits hard and acts as a Ferocious trigger; I'm not fond of the 2 Toughness, but the Flash ability is good and if I have mana to burn, using its Bestow ability is a great way to get value out of a single card.
Rancor is a very efficient enchantment that makes any creature on the board into a viable threat. Its graveyard recursion means it can be played at any time with little-to-no risk, and that also keeps it from being a target for enchantment removal.
Curious to see how this plays out! The only other major change I see that I could do is swap the Rattleclaw Mystics for Sylvan Caryatid for more better ramp and blocking. We'll see.
