Moudou I'm not really sure what you mean by Flying being weak offensively, considering most people feel it's a very powerful offensive typing. If you mean the STAB moves, then yeah, Flying does have some shits STABs.
Water / Fire sounds interesting. I actually really like this combo. It teams with Lando, Terrak, and other Fighting types like Loom. It helps switch into Fairies, and beat Grass quite easily with its Fire STAB. It does, however, struggle against Water types, which makes Rain a really hard matchup. It also means that we're weak to both EQ and Rock Slide, limiting switch in opportunities.
Fangame10 Sand Force is kinda meh overall anyways, so losing that as a potential ability really isn't that big of a deal.
I think Water / Flying and Water / Fire are both really nice. I'm kinda iffy on Water / Flying though because Rotom-W hard walls us lol. Water / Fire sounds nice as well, but then we get walled by Keldeo, so it kind of seems like a pick-your-poison type of thing. Electric / Flying also sounds really interesting, and I think with Hidden Power Ice, it'd have a pretty easy time dealing with Lando-T. We could also remove things like Ferro with the right support. It doesn't give us a switch in to Fairy- or Rock-type attacks, though, which kinda sucks. However, with Sand Rush + HP Ice, I'm wondering how much that'd matter once you're able to get it out onto the field.
I think the main issue with Flying-type, though, is the STAB issue. Making us a physical attacker is a no-go imo, especially considering how important it is to beat Lando-T. Because of this, I really like Water / Fire for the fact that it doesn't rely on a shitting Flying STAB. However, it isn't all that great defensively, which is something we need to be careful of. It also lacks a way to hit Fighting super effectively, making Keldeo and AV Conkeldurr problems :[. Maybe we could give it like Psychic?
