Invalid Let Miraidon have 31 Attack IVs by default and make the default Tera type dark instead of your first typing

[Pokemh]

Miraidon is never a physical attacker and is pretty relevant in Ubers and AG so having to change it manually for tour games and general laddering seems like a hassle and it counts your Tera type as Hidden Power Type for some reason but Showdown makes the first type the Tera type it gets on default.

This seems like a pair of bugs to fix rather than a suggestion, try posting in bug reports please!
