Spoiler:
Guide to Destruction
Creature - Eldrazi
When you cast Guide to Destruction, you may search your library for a colorless creature
card with converted mana cost 7 or higher. If you do, shuffle your library, then put that
card on top.
The first creature spell you cast each turn costs less to cast.
5/5
