The name Master Jouster was already taken.

Joust diehards rejoice! This is the card you were waiting for. Whenever a joust effect is triggered, your minion revealed will always be this one.

A few clarifications:
-It gets revealed if it's in your deck OR hand, not if in play or dead. This way it doesn't become a dead card if you draw it before a joust (plus flavor!)
-The Cost reduction triggers whether you win or lose the joust, meaning the first joust costs 12, the second 9 and so on.
-It CAN become a deadweight and lose you all jousts, but that's intended! You're not supposed to win them all, and the purpose of this card is to make a terrible mechanic actually reliable.
