Doesn't Arcanine already have Close Combat? Though it would be a boon. Scizor could use physical HP Electric and finally no longer be walled by Jellicent, Tentacruel, and Gyarados. Physical Landorus could use physical HP Ice to hit Dragon-types harder. This would greatly reduce the need to use the unreliable Stone Edge and the weak special Hidden Power Ice. However, it would be an even major boon for Kyurem-B, which lacks a physical STAB to work with. Although it is still weaker than even Dragon Claw, a physical Hidden Power Ice would give Kyurem-B a reliable way to hit many things hard without the need to use Outrage, such as Hippowdon, Celebi, and Ferrothorn (which is 2HKOed).
