I'd be happy if we ONLY got the Predatory Fighter rule. This is awesome!
Yeah, but D3+1 attacks with Killing Blow is pretty awesome. And I assume they still have Vanguard for being Fast Cav, so a Turn 1 charge is completely feasible, if not by Turn 2. I can see us pointing these guys at support units like Cannons pretty easily. Especially if the cost is right. Plus Skinks are historically Initiative 4 so they'll likely get to kill whatever they hit if they aren't too numerous. Glass hammers for sure. I'm curious how the frogs work exactly. Gonna be a fun unit to play around with.
I'm seeing some fun Drop Rocks + Flaming Bola combos in my head. Bye-bye Treemen, Hell-Pits, and Hydras
