This team aims to use the currently unranked Hisuian Decidueye as an offensive threat instead of its usual niche as a Defogger that beats Mega Tyranitar. Even without any bulk investment, Hisuian Decidueye completely stonewalls Tyranitar and lures in many of its common checks, most notably Mega Venusaur and Clefable, to OHKO them with a +2 Z-Brave Bird while still being able to threaten Aegislash with Scrappy Triple Arrows. Aegislash and Life Orb Clefable are two Pokemon that appreciate Venusaur being gone and complement each other as breakers by wearing down shared checks for each other, such as Celesteela and other specially defensive Steel-types. The sand core of Mega Tyranitar + Excadrill provides speed control, hazards, hazard removal, Pursuit trapping, and an extremely strong Knock Off all in two slots, and Celesteela rounds off the team as a general special wall that becomes quite the threat with annoying Leech Seeds if Hisuian Decidueye can remove the opposing Grass-type.
