In theory, Transform + Imprison Smeargle does this.
Also true, but this wouldn't have to Transform. Also, as good as Smeargle can be in ideal circumstances, I'm thinking something that could take a hit on the switch in, something Smeargle cannot claim to do. And again, I turn your attention to the second to last sentence.
EDIT: To above poster, I mean bad attacking stats, good defence. Survivability, not blitzkreig.
