[Overview]
With no Sleep Powder, poor stats save for a decent Special Attack, and an awful typing, there's seriously no reason to consider Beautifly, even in NU. It's outclassed in every way by at least 10 other Pokemon, and directly outclassed by Butterfree and Masquerain, both of which themselves are poor Pokemon. Don't use this Pokemon, even on gimmick teams.

[SET COMMENTS]
- Switch in on Hitmonchan and click Stun Spore
- Psychic + HP Fire makes use of Beautifly's Special Attack and has good coverage
- Morning Sun to keep Beautifly around and annoy your opponent even longer
