Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Wait, add back Hidden Power, but make it have 80 BP if it matches your type (can be either if it's dual-typed) Also an be physical or special depending on which is higher.
Basically have it change type like your hidden power IVs as opposed to being a tera type, so pretty much better hidden power that physical attackers can use.
Terastallization is removed, but Tera Blast typing is based on your Hidden Power type instead. Would that make it more or less overbearing? I don't actually know.
