Grand Spin

From BoardGameGeek:

Grand Spin is a fast-paced 1-on-1 dueling card game where players build 20-card decks from over 120 unique champions and duel to reduce their opponents life total to 0. With a unique resource system, fast paced duels, card synergies and battles decided by the spin of a top. It is easy to learn but difficult to master. Players take turns sending champions to battle from their bench, activating their unique abilities. If a champion in battle shares a type with a card on their bench they can also activate their type bonus. Once both players have selected their champions and have activated all abilities and type bonuses, players spin their champions on a magnetic top to battle. Each side of the card has an initiative number, when the cards stop spinning the initiative numbers facing each other determine what card gets to attack. This repeats until one card is destroyed, the winning card deals its attack to their opponents life total. After battle the winning player refreshes their bench with champions from their deck and starts the next round.
