I suppose I'll need Heal Bell on Clefable because everyone wants to poison it.

And Thundrus/Raikou/Ferrothorn.
Now I think all of these are great sets, but are you sure your replacements for Dusknoir can effectively combat a Gale Wings Talonflame with its priority? Or will Starmie be able to do that effectively?
Other checks/counters to Talonflame include Heatran and Wash Rotom. As for previous suggestions, Thundurus also helps vs. Talonflame, as it can cripple it with Thunder Wave. Gliscor also fares decently against non-Choice Band Talonflame.
