You still have Scizor with Superpower. Most people use such pokes as Lucario/Terrakion to come in and hit Bliss/Chans with a Close Combat. Same basic principle. Using Choice band on Scizor I'm guessing your using him as a "get in - hit hard - get out" poke, so it works very well, especially with the extra power Band gives it.
Using Superpower on Blissey with your Scizor:
