Back when my brother and I had our birthday party together I made him a Magic: The Gathering treasure hunt with clues I made to look like Magic cards (using this set editor). I tried to vary up where the "hint" was--from the picture to the flavor text I wanted to make it exciting to read the card (and not too hard). Making them reminded me of the Unglued set and now I am wishing that there were more humorous cards in Magic. Anyway, it was fun, and here are the clues. Feel free to steal them for your own treasure hunt, but making them is so fun that I recommend that.
