Whenever you reveal a Thought, you may draw a
card and scry 1.
{x}{x}{u/r}, {t}: Shuffle your library. Scry X.
{p/r} or {p/u}: Create a Thought token and put it on
the bottom of your library. (It's a token with
"You may reveal this card. If you do, its ceases
to exist." This token does not cease to exist in your
library or hand, but does anywhere else.
This token is a card.)
