Icicle Spear is useless for Multiscale since you OHKO through Multiscale anyway with Icicle Crash, even bulky Dragonite doesn't stand a chance 87% of the time. I can't really think of anything that uses Focus Sash that you would want to hit with an Ice attack other than Dugtrio. Speaking of Dugtrio no Dugtrio will ever tempt to try trap Mamoswine in fear of Ice Shard. Ussually the teams with Dugtrio on them also uses it for SR, so if they wanted to trap Mamoswine, they have to spend that turn killing with Reversal (since ussually the just go to sash immediatly) or setting up SR, but it can't do both. So killing duggy is out.
The only real use for Icicle Spear is to kill SubDD Dragonite, SubToxic Gliscor, and Substitute Landorus (all behind subs).
I beleive you guys are forgetting the significance of using Icicle Crash: killing Skarmory. Much like Gyarados, Skarmory can not reliably Roost stall or stay in Mamoswine to set up Spikes due to that nasty 30% flinch chance. I think getting by one your best checks/walls and potentially abusing the flinch chance with paralysis support is much more valuable than covering some fringe threats.
