Showdown

From BoardGameGeek:

Take aim and draw in Showdown, the chaotic Wild West card game where quick thinking and sharp reflexes reign supreme. Players engage in intense shootouts by playing attack, dodge, or block cards to survive until the dust settles. With its simple mechanics and unpredictable gameplay, Showdown delivers endless excitement in a fast, easy-to-learn format. Whether you're dodging bullets or landing the final shot, every turn is packed with suspense and laughter. Saddle up-Showdown is a must-play for fans of the Wild West and action-packed fun! In Showdown, two players engage in a shootout until only one remains standing. Each player starts with 7 life points and a hand of six cards, with the remaining four cards forming a face-down reserve. Each player simultaneously reveals a card - quick draw, aimed shot, swift dodge, etc. - then determine who gets hit, which can be both players! If you play a lucky coin, you draw a random card from the reserve for your turn. After you shoot all the cards in your six-shooter, you shuffle all sixteen cards, then deal out new hands and a new reserve. Keep playing until someone's life hits zero, with the winner burying them in an unmarked grave.
