Favors something more complex and likely longer than most would like. Imagines multiple decks of cards. Draws from the green-backed cards in Viridian Forest, the brown-backed cards in Mt Moon, the yellow-backed cards north of Cerulean City, and so on. Probably wants maybe fifteen individual decks of these.
Made a quick mock-up of a card in Paint.
- HP: Amount of hitpoints. Recovers all health after battle.
- Catch: Rolls a six-sided die to catch it. Must roll equal or higher than the Catch number. Receives an additional 1d6 for Great Ball and 2d6 for Ultra Balls. (Perhaps require you to roll equal or higher than (Catch - missing hitpoints)?)
Flips a coin to see who attacks first (or have a Speed number). Always chooses wild Pokemon's highest-listed attack for its action (Spark, in this case). Heals all damage (except fainting) after combat.
Occasionally faces a trainer instead of a wild Pokemon. Draw X Pokemon from the deck, as dictated by the trainer card. Receives money for winning. Uses that for Pokeballs and healing items.
May visit a town to heal fainted Pokemon and buy items.
Races to defeat the Elite Four and Champion. Draws their team from their own personal decks. Wins by defeating the champion.
Obviously needs refining. Left out gym leaders, evolutions, switching, and other things. Came up with this in a few minutes, though. Conveys the idea, hopefully. Mashed together the TCG and Arkham Horror, more or less.
