There is no need to do egg moves because moves will be reset when the Pokemon is transferred to S/V. Though learning egg moves is easy in S/V (just need to hold an item and picnic together and it is instant. No need to breed or come from the same egg group.), so don’t worry about that.

Have you decided what starter you are going to choose for Violet? Maybe a Pokemon that covers your starter’s type weakness.

Happiny's in, no worries there.

Are you trying to keep it to the regional Pokedex, or are you okay with transfer-only Pokemon like regional forms?
