I don't understand why people want to increase the star count in every deck. If it can be vastly improved w/ a few more stars that I highly recommend it but a lower star can work just as easily as you will be playing more lower star decks.
Herman --> Hefty just cause Herman has a 5 point penalty
There's not much else that has to be changed as it's a Standard deck.
Ace --> Ficcanaso/Ivy(?) really just preference based on play style
Ace/Gianfranco --> Jimmy/Aniki(?) a possibility
Herman --> Lady(?) while DRs are not really optimal sometimes people are conflicted whether or not to pill against a DR (though Hefty is probably better)
Harold --> Maurice(?) same reason as above
