I personally like the set of:
Weakness Policy
-Dragon Dance
-Dragon Claw
-Extreme Speed
-Fire Punch/Earthquake
With Multiscale making it tank Ice type moves, pairing it with something that just attracts Ice on a team seems to work out well. Things like Gliscor and Landorus-T, etc. As it's a safe switch and can get the +2. Another option is sending it in as a check and DDancing to get the speed as they switch. Then you can still tank the hit they thought would kill, and of course, unless they know what to predict, you will likely get the ice/dragon/fairy hit and get the WP boost. Such a fun set to mess with. Fire Punch is basically my own preference to hit back Ice types hard such as M-Abomasnow and Mamoswine. Also because of Genesect running around. But mainly, it was to cover my team with Scizor. EQ can of course be useful for many reasons: Aegislash, Klefki, M-Mawile, Infernape, Heatran, etc. Though, those pokes are less likely to be sent out at DNite. The one way you can really counter this is by having Priority practically, or making Multiscale break with things like Fake Out and a Neutral move, then going Ice to hit it. But generally, you can have the speed boost already and be able to outspeed them.
