Blue Moon is a blue-red control archetype built around disrupting opponents with countermagic and removal while using Blood Moon to punish mana bases that rely heavily on nonbasic lands.
For this archetype, Blood Moon or Magus of the Moon turn nonbasic lands into Mountains, various counterspells stop troublesome spells before they resolve, and Lightning Bolt and other efficient burn spells provide clean removal or the final points of damage for the win.
