Tall Tales: My Favorite Mechanism

About Tall Tales, from BoardGameGeek:

We are social creatures, natural storytellers. It's how we retain memories of life's important events and share them with our community. Of course, some of these stories become larger than life, taking on a mythic status as details grow and embellishments are added. We give these obviously outsized stories a name: tall tales. In the trick-taking card game Tall Tales, players begin with modest card values in their hands that represent young stories before their repetition. Over the course of several rounds, hands will be sculpted to contain more valuable cards representing the stories' growth over time. Whoever has the highest card values at the scoring round and the end of the game has won as the best storyteller with the greatest tall tale.
