If you want an unconventional support who can also go mid easily, I'm told Anivia isn't bad.

Pros: Q stuns for 1 second and slows for 3 (or just slows if the detonation misses) and is a pretty vicious poke, W has obvious implications for Supportnivia, and R as an AoE slow and AS debuff would be pretty good for shutting down the enemy carry. Rebirth can be useful for baiting a tower dive, or making people focus your egg while your carry gets away if it comes to that.

Cons: Incredibly mana hungry. Philo wouldn't cut it, you'd need at least a Chalice, which does build to Mikael's later but isn't very good as a support item in the meantime. Crystallise has incredible potential but the ability to use that well is what separates the good Anivias from the bad. Use it badly, and you'll be more disruptive to your team than anyone else on the enemy team could dream of. Almost definitely better as a mid champ, just because she's so good there. And of course, unconventional support = people assume you're trolling = if you do badly at all people will yell at you, even if you were doing everything right and your carry just sucked.
