Crossing the Chasm by Kevin MacLeod
Adventure, Ho! Last time on "Adventure, Ho!", the mage-orc Gnarlnosh was granted 1d4 wishes from a Deck of Many Things and it totally screwed up the game balance. Why? Because the DM sort of sucks, but he thought "Oh, sure - this could be fun... how could giving a mage-orc a fully provisioned army in the middle of a desert possibly sidetrack the quest for finding a cure for a magical disease that is ruining the kingdom AND the healer elf." Deck of Many Things; BAH! More like Deck of This-Campaign-Jumped-the-Shark.
