I’ve been developing a short-form competitive card duel designed around symmetry. Both players use identical 40-card decks. No deckbuilding. No rarity tiers. Matches last 5–10 minutes and focus on: • Resource efficiency • Infrastructure timing • Reactive stack play • An Overrun rule that discourages stalling There’s an instant AI opponent and online PvP. I’m trying to validate whether the symmetry creates depth over multiple matches.
