What do you want from a Switch Pokémon Stadium game?

I hope that the tumor mill is correct and we're getting a Stadium game for Switch that connects to Home. What features would you want in it?
Things that would be nice
>Ability to set my own rules/time limit on battles.
>Return of 3v3 battles
>Direct connection to Home. No need to fuss with apps

Things that are needed so the game actually has content and can be sold to John Casual to prevent it from flopping.
>Rental Pokemon
>QR code team scan feature like in SwSh
>Mini games
>In game challenges like the various cups and Gym Leader Towers
>Add in something like the PWT
>Lots and lots of unlockable (and buyable) customization options for your trainer avatar. (Maybe some Gatcha element?)
Thoughts?
