Tres Tesoros

From BoardGameGeek:

Tres Tesoros is a fast-paced card game for 2 to 8 players that combines strategy, luck, and treasure hunting. Players roll a custom D12 dice at the start of their turn to determine how many cards they draw and how many actions they can take. Throughout the game they collect Gem cards, protect them with Shields or Mirrors, and use special action cards to disrupt their opponents and gain an advantage. The goal is to complete a winning collection of Gems before anyone else. Easy to learn and quick to play, Tres Tesoros offers constant interaction and unexpected twists where a single roll can change the course of the game. -description from the publisher
