Welcome to the game and thanks for the post! You had amazing luck opening your rare packs! Two shadow cards (that are good cards) and a legendary from just rare packs? Amazing.

Some advice on the Star Store ('vials' resource). For now, don't burn your stars buying shadow/meteorite welcome cards. Instead, save your stars to pick up copies of cards you don't have (you want 2x of each card). This will help you build more competitive decks, which helps you win more rewards.

Hope you continue to enjoy Gods Unchained!
