Creating a SIMPLE card game for children - Zing-a-Zam!

About Zing-a-Zam, from BoardGameGeek:

Mirror spell here, freezing spell there - no one is prepared for what might come next! Young wizards from all over the land have come to participate in the “Tournament of Wizardry”, the biggest magic competition in the world! The object of Zing-a-Zam is to gather the most cards into your score pile throughout the game by playing different spells and trying to outsmart your opponents, although you might struggle to predict your own moves as all players play with their cards facing other players. -description from publisher
