Houndstone

Houndstone is the reason this team exists. Sand Rush lets it outrun Basculegion, Garchomp, and most Choice Scarf users the moment sand is up, while still carrying enough bulk to live a Mystic Water boosted Wave Crash from Basculegion. Adamant with split Attack and Defense investment keeps Last Respects lethal even at only 100 base power once teammates start fainting, and Will-O-Wisp punishes the physical attackers it now outpaces. Ally Switch turns a predictable hit into a wasted opponent turn by redirecting it into Houndstone's bulk, buying the extra turn the sand core needs to close games out.
