30th Anniversary Edition

Raging River

Whenever one or more creatures you control attack, each defending player divides all creatures without flying they control into a "left" pile and a "right" pile. Then, for each attacking creature you control, choose "left" or "right." That creature can't be blocked this combat except by creatures with flying and creatures in a pile with the chosen label.

Intl. Collectors' Edition

Unlimited Edition

When you attack, non-flying defending creatures must be divided as opponent wishes between the left and right sides of the River. You then choose on which side of the River to place each attacking creature, and attacking creatures can only be blocked by flying creatures or those on the same side of the River.
