I use rhymezone often, but I don't like it because I consider it cheating.

To be clear, I don't want to use haiku specifically. I was looking for a short form from the western European tradition for air elemental spells. After discovering both the American cinquain and the Spanish quintilla, I decided to combine them. With the cinquain, there are longer forms which involve mirroring the structure:

2
4
6
8
2
8
6
4
2

^ for "butterfly" mirror

2
4
6
8
2
2
8
6
4
2

^ for strict mirror

What's getting me is the final two syllable line. It's difficult to finish off an idea. Perhaps I should use iambic commands on both the first and final lines. I have to play around with it.
