Marvel/Harry Potter AU.

As aurors, both Clint and Natasha exceptionally adept at their jobs. Natasha is the best at creative spell-casting and is excellent at coming up with just the right spell on the spur of the moment, no matter how much pressure she might be under (she has even been known to concoct a few spells of her own). Clint, on the other hand, is especially good in wizarding/spell-casting duels, because when it comes to casting spells, he never misses.

(I like to think certain specifically enchanted tattoos (wizarding tattoos?) work the same way as photographs in the Harry Potter world. It would be so neat to have something moving with limited mobility on your body, like a lion that roared, fire that crackled and shifted, or a flag that waved (all silently, of course).)
