- 15 April 2013No monocolored creature will be able to block that turn, including monocolored creatures that enter the battlefield after Awe for the Guilds resolves. A creature that’s monocolored when Awe for the Guilds resolves but somehow becomes multicolored before blockers are declared will be able to block.
- 15 April 2013A monocolored creature is exactly one color. (Colorless creatures aren’t monocolored.)
