What new Magic the Gathering keyword would you make?
MtG has quite a few thematic abilities. They began with the basics, such as flying and first strike, and now release several new abilities every set, such as Wither or Hellbent. However, they haven't explored all the assets of Magic by a long shot. What types of abilities would you make? What conditions would you explore? Include the ability's name, a description of what it does/how it works, and an example card or two.
