Valiant tanks any hit from Hoodra after Spirit Break and any hit from Ursaluna after Reflect, rest in Attack.  Hearthflame tanks a Bandorus-Therian Stone Edge, 4 speed for creeping max speed Corv just in case, rest in Spdef for better LO Spectrier rolls if they have max spatk investment.  Pecharunt tanks a specs PZ hit while optimizing HP, rest in Spatk, last move can honestly be changed if needed.  The team is a bit weak to some random mid/low tiers like Landorus-I and Manaphy (though Manaphy would lose to a more normal Ogerpon set).
