I would recommend using the Fairy Commune as a beginner deck. Try using cards like Fairy Queen to increase your damage and heals but mainly use Fairy Fire it will deal 1 damge but it will increase by 1 damage everytime you use it and also use Take Flight while in hand it will heal 1 hp at the being at your turn and when play gain 3 hp and draw. This game is difficult but don't be afraid to try new decks.
