Sanar, Unfinished Genius // Wild Idea

Sanar, Unfinished Genius: 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. Wild Idea: Search your library for an instant or sorcery card, reveal it, put it into your hand, then shuffle.
