Cute, but it broadcasts itself and doesn't get to switch in ever. Switch out to something else, then do another switch to something that can handle the first thing you switched into. Boom, neutered.Smeargle @ Choice Scarf

If you do not out speed a scarfed smeargle then you cant attack.
Really, if you want a Scarfed Transform user, just run Mew. It's massively bulkier, doesn't give the opponent a free turn to switch out, and it can revenge kill things that have boosted their Speed.
As far as Imprison users go, I feel like Lando-T with an Imprison trademark and HP Ice could be a really funny way to check Electric-types (and it's not like HP Ice is bad on Lando either), and the rest of its standard set is generic enough (Stealth Rock, Earthquake, U-Turn, Knock Off, Stone Edge) that you can probably switch in and fuck something up in most games. Most teams probably have something better for Lando to do, though.
