How do you get your Pokemon card to five stars Ruby?

You're asking about getting a Pokemon card to "five stars" in Ruby, but that isn't a feature within the Pokémon Ruby game. There is no star rating system for Pokémon cards within the game.

It sounds like you might be thinking about a different system, such as:

* Pokémon Trading Card Game (TCG): In the actual trading card game, cards have different rarities (Common, Uncommon, Rare, etc.) and some have special features like Holofoils or Reverse Holos. This may be what you're referring to.

* Pokémon GO: In Pokémon GO, Pokémon can be rated with Combat Power (CP) and have different IVs (Individual Values) that affect their stats.

If you're looking to learn more about a specific Pokemon card game or system, please provide more information! I can help you better if I know what you're referencing. 😊
