If this card had no text other than “Myriad. Fast. Science,” it would be worth a pick for Kate. Up to three clues can be put on it for up for 0 play actions. As it is, it gives a lot of flexibility to people who want to draw through their deck quickly (which is most people in Seeker).

The cancel effect is great for Agatha, or anyone. Unlike defiance(0), you get to pick at the moment which you want, and it even replaces itself!
