Little Kingdoms

From BoardGameGeek:

Little Kingdoms is an addictive high-stakes card game where two rivals clash in thrilling, fast-paced duels for control over four kingdoms. Recruit fantastical characters with powerful abilities, strategically manipulating the tide to tip the balance in your favor. But beware...the Queen, a ruthless force, reigns as an unforgiving referee, and her judgment is swift. She will banish any weakened characters from her presence and unlock ancient portals that connect to the elemental forces of this universe. With each portal that opens, the stakes rise dramatically, unleashing epic confrontations. Your goal? Reduce your opponent's mana to zero before they do the same to you. In this game of merciless strategy and unpredictable twists, only the most cunning will emerge victorious. Every decision could tip the scale toward glory-or doom! Will you conquer the kingdoms, or will the Queen's judgment seal your fate? -description from the publisher
