i'm a big bl player and have to say meteor over claw, eq would hit all non flyers/levitaters, and stone edge on the predict is all you need. If you later find they have something like calydol to avoid both just predict and u-turn. Also if you're going to run a more bulky mach punch set on hitmontop make it look like this, changes are bolded.

Running an adamant technician set doesn't need the close combat. No blissey will ever stay in with it fear the outspeeding and cc, giving you time to bulk up and mach punch. If you really want to keep the cc then swap out rapid spin, it doesnt hurt your team too much. Also if the bliss decides to stay in, then bulk up and mach punch for the ohko next turn anyways. The only real threat bliss would have against it is probably psychic, but thats probably a 1/10000 kind of thing lol.
