Wee Folk

From BoardGameGeek:

In the hush of twilight, where moonlight threads through ancient leaves, the Wee Folk stir. They dance in patterns unseen by mortal eyes, leaving trails of magic etched in shape and shadow. Wee Folk is a two-player game of gentle rivalry, where you'll slide cards like stones across still water, weaving polyomino patterns to echo the hidden sigils of the fae. Where strategy wears the robes of story, and each game is a spell softly cast. Wee Folk is a 2-player card game where you are attempting to arrange various Wee Folk into pattern in order to collect them. Collected cards might include actions which may be spent to alter a player's personal tableau. Cards shift in a "Candy Crush" style whenever sets are removed from the play area. -description from the publisher
