Unlike most CCGs, "UFS" does not have monsters, creatures or similar. Damage is dealt by playing attack cards, which the opponent may try to block with using a card from their hand. Each attack has stats for speed (how hard it is to block), the damage it will deal, and a zone (high, mid or low) that the opponent's block must match to avoid taking damage. Attacks often have abilities on them, and may be enhanced by abilities on other cards.
