Mega Clefable Sand

Synergy

Tyranitar sets sand to activate Excadrill's Sand Rush, doubling its Speed while chipping down the field. Mega Clefable uses Follow Me to redirect attacks onto itself, giving Excadrill and Kommo-o free turns to run Swords Dance and Clangorous Soul. Flying typing means Excadrill can fire Earthquakes with Clefable on the field without a Protect turn. Kommo-o and Excadrill cover each other's weaknesses, with Steel deterring the Fairy types that threaten Kommo-o. Rotom-Heat's Choice Scarf Volt Switch into Tyranitar is a key anti-weather pivot, and Basculegion absorbs Fighting-type attacks aimed at the sand core.

Win Conditions

Get sand up with Tyranitar, then use Mega Clefable's Follow Me to protect Excadrill while it uses Swords Dance. A plus-two Adamant Sand Rush Excadrill under sand is the primary win condition against most teams. Against Rotom-Wash or bulkier matchups, use Kommo-o to set up Clangorous Soul behind Follow Me and sweep. Basculegion closes out games where opponents have fainted, stacking Last Respects damage.

Lead Options

Clefable + Excadrill, Rotom-H + Excadrill, Tyranitar + Excadrill, Clefable + Rotom-H, Kommo-o + Clefable

Threats

Rotom-Wash walls Tyranitar and Excadrill and cannot be easily threatened by much of the team outside Kommo-o. Mega Froslass is dangerous if Rotom-Heat is not brought or positioned quickly. Strong Rock Slide or Blizzard spread moves can threaten Mega Clefable before it has redirected enough damage, especially when Clefable's flying type makes it a spread target. Kingambit with Black Glasses becomes a problem if Kommo-o and Tyranitar are both unavailable.
