Ahri control budget

Play cheap unit, control opponents on showdown, use convergent mutation to buff your units. Lecturing Yordle and Mundo or Tasty Faefolk make a good defensive combo. Tagon's Peak should be your first battlefield, following The Dreaming Tree. Keep Defy for important spells, like signature spells or powerful units. Go slow, think on what to counter or to debuff, and win by keeping battlefields with Ahri.
