Pietra, Crafter of Clowns

Haste
Robots you control get +1/+1.
{R}{W}, {T}, Tell a joke you haven't told this game to someone outside the game: Create a 1/1 white Clown Robot artifact creature token. If that person laughed, the token gains haste until end of turn.

Each Pietra you control knows what jokes you’ve told that game, even if that Pietra wasn’t under your control when you told that joke.

Each joke you tell should be appropriate for the audience, keeping in mind that not everyone in attendance may be aware of your personal comedic stylings.

Even the mildest laugh counts. A giggle, a guffaw, a chortle . . . they all give the Clown Robot haste.

Pietra keeps a list of jokes for every player. If another player gains control of Pietra, they can tell a joke you’ve already told, as long as they haven’t told that joke yet.

Robot is a creature type. There may be creatures that appear to be robotic in nature that don’t have the Robot creature type. They won’t get +1/+1 from Pietra’s second ability. That ability affects all Robots you control, not only the tokens created by the last ability.

While you must use a new joke each time you activate Pietra’s ability, you may choose the same person as the audience, especially if they think you’re funny.

You may find yourself drawing quite the crowd as your joke-telling skills become legend. Make sure you identify one specific person outside the game before your joke. Only their laughter (or lack thereof) matters, even if others are rolling on the proverbial or literal floor.

You may read the joke from an outside source if you need to.
