Another game loosely inspired by fairy tales, Frog Juice. This one uses some general fairy tale tropes, mostly the generic witch tropes found in fairy tales.
Here's an editorial review from Amazon:
How would you create a magic spell? You might need some unicorn horn or some eye of newt, or maybe some bats or toadstools or star and moon dust. But be forewarned as you're stirring up your potion--you'd better be wary of a black cat or the powerful All-Purpose Witch Wash! One of your opponents might even be brewing up an Uglifying Spell. ("Results guaranteed to crack mirrors at a single glance!") All of these magical ingredients are part of Frog Juice, an imaginative card game for two to four players that uses fairy-tale elements from fair maids to frogs to create a game that both kids and adults will enjoy. This game of strategy includes 44 ingredient cards and 15 power cards, each with an illustration that looks like it came straight out of a fairy-tale book. Cards are played in the center of the game and then captured by other players by matching numerical values or by using stronger powers. --Marcie Bovetz
And a description from the manufacturer, Gamewright, which isn't as helpful:
A clever card game of spells and concoctions. Cast spells, brew concoctions, melt witches...use a smidgen of math and a pinch of probability. Capture cards by matching or adding cards from your hand. Then count ingredients and measure your powers.
The game is said to promote math skills which is always a good thing, too.
