Edit2: also, can snorunt's card be upgraded into a froslass card?
(Sorry for submitting 9 questions at once haha @stochastic love your game to this degree )
1.changing the date on your computer is not supposed to work and may cause bugs with the auction
2. Empoleon has no gold-type moves. Tidal Wave has 100 bp and no you can't use the move in the first slot after fusion
3. You can find data electivires as a static encounter in the future. At least before you finish the game, idk if there is one in future 2.0
4. Nope. Secret.
5. x1.1 for each star
6. Well, you can't. Just keep trying. May check compatibility in the official games as areference but its not the same. Here's a list taken from the community poll for tutor moves though.
Aurora Veil: Alolan Ninetales
Quiver Dance: Altaria, Gardevoir, Roserade(?), Ribombee(?)
Dark Pulse: Porygon-Z
Dragon Dance: Dragonite
Darkest Lariat: OM_Ursaring
Dragon Ascent: Dragonite(?), Flygon(?)
7.Route 104
8. Anything is possible in randomizer mode or in the auctions at Sylen City, otherwise legendary locations (if any) are secret.
9. Yes, but you need a special upgrade for pokémon with multiple evolutions. I think its in the vending machine in the card shop
