Phantasmic

From BoardGameGeek:

Members of the elite Phantasmic Dueling Squad routinely test their skills against each other. Employ your knowledge of counterhexes to prove that you're the best of the best. Prove your magical prowess in this strategic bluffing game. Play spells and counterspells against each other in rotating duels. Make use of each spellcasting style's abilities to turn the tables on your opponents and trick them into making a mistake! Each turn the Leader picks a Challenger and targets them with a spell. The Challenger plays a counterspell and declares whether it is stronger or weaker than the Leader's spell. The Leader must decide whether to believe the Challenger or not. The Challenger then reveals their card, resolving any revealed effects. If the Leader guessed correctly, they win the duel and keep the Leader role; otherwise they lose the duel and the Challenger becomes the next Leader. Play until someone wins or loses 3 duels. The first player to win 3 duels is the winner! Otherwise, if any player loses 3 duels, all other players win!
