One Attack!

[Cherrim]

Speaking as someone with insomnia, I think Rest would be a pretty great attack to be able to use...

But I won't say it, that sucks. I'll go ahead and be clichéd in conjunction with my username and say that I'd like to be able to use Sunny Day. I really dislike rain when I have to leave the house so it'd be nice to be able to switch the weather to clear and sunny so that I wouldn't have to be rained on. n_n (I probably wouldn't use it much in winter though... I love snow! It's mostly just rain that I hate when it comes to precipitation.)

Ugh I was going to say Thunderbolt because it's a favorite of mine but there are others more useful. xD;;

Going to hop aboard the Teleport boat then! Flying is awesome but I doubt I'd be able to actually fly very far due to weather, exhaustion, and other things.

Having a hard time deciding between Wish and Flamethrower.
Wish: Everything you want comes true.
Wait, Flamethrower allowes me to breath fire...
This argument is invalid.

Blizzard and Leaf Blade are personal favorites, but I don't think they'd really be useful in real life. ^ ^; So, I'm going with Pay Day. Pretty self-explanatory, really. However Telekinesis, Teleport and Wish seem tempting as well.
