I was talking to @Hys about typings just now, and he mentioned something interesting to me: Dragon / Flying typing. He said he'd like for me to post my thoughts on it here, and I'm actually thinking this would be a cool typing to consider for this CAP.

Dragon / Flying is surprisingly similar to Grass / Fairy (which I'm still supporting). For one, Dragon / Flying absorbs the Grass-, Water-, and Ground-type attacks aimed towards most sand teams, much like Grass / Fairy, but it lacks the weakness to Flying-type attacks and is fully immune to Ground-type attacks. For sun teams, Dragon / Flying resists Ash-Greninja's brutal STAB Hydro Pump for its Fire-type teammates and also can smack around the opposing Dragon-types that give those teams trouble. It's pretty interesting to me how similar these typings really are in what they do.

Of course, as with any type combination, Dragon / Flying doesn't come without its flaws. For one, a 4x weakness to Ice is pretty glaring, but I certainly don't think that's a complete deal breaker. The Stealth Rock weakness also hurts too, but it's also immune to other hazards, particularly Sticky Web, making its projected role on a sun team cleaner much easier. Ash-Greninja's Dark Pulse also can chunk this Pokemon harder than Grass / Fairy. Overall, Dragon / Flying addresses many of the issues that Sun and Sand teams face, much like Grass / Fairy does.
