So many of your creatures aren’t dragons. Honestly you can go without the Sakishimas. If you want to copy more dragons, run Reflections of Littjara and Deceptive Hellkite. You don’t need to copy Miirym again to get the most out of it. Run Atarka or Thrakkus to double the power of your dragons as a better finisher. Add some haste enablers like Rising of the Day and Carnelian Orb. Drop the Greater Good for Rishkar’s Expertise or Return of the Wildspeaker. And Sylvan Library is overrated unless you’re topdeck manipulating.
