Planar Chaos is the second set in the immensely popular Time Spiral block. This set asks the questions "What if the colors of Magic did different things?" and "What if past events in Magic's history turned out differently?". The red card Ball Lightning is printed in this set as the green Groundbreaker. The white card Wrath of God is the black card Damnation, and Akroma, Angel of Wrath is now Akroma, Angel of Fury. The set did strange and powerful things, the likes of which haven't been seen again.
Look for the following key cards:
Akroma, Angel of Fury
Simian Spirit Guide
Urborg, Tomb of Yawgmoth
