For collectible card games (CCGs) or deck-building games, Tabletop Simulator is an excellent platform for testing new strategies. You can easily import custom cards or use existing card assets to construct and refine your decks. Use the 'Deck' component in the 'Objects' menu to create new decks, then drag and drop cards into them. The ability to quickly reset and rebuild decks makes it ideal for iterative design and competitive playtesting.
