Sanar, Unfinished Genius // Wild Idea

Card text

Sanar enters prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)

{T}: Create a Treasure token. Activate only if you've cast an instant or sorcery spell this turn.

Search your library for an instant or sorcery card, reveal it, put it into your hand, then shuffle.
