With all the new planet artis available in mind, would someone provide a blueprint for us to reference on how to properly go about making and structuring the mission exotic planet.

Put everything that's better then size1:arti1 first, (no more then 2 +24s), then everything thats 1:1, if there is space left, build a 3rd standard structure.

so what about the planet itself before it is hyper transformed? take from someone? use one of your own?

Make sure the planet is a: Desert, Terra, or Icy. Place adaptive spires on it before using the hyper terraformer. Doing that nets you extra AP production.

I suggest getting a planet that has rings on it for ALL of your mission planets. In the case of saving your rifts for natural dysons pray the transfuser gives rings then sacrifice a goat, 3 chickens, 5 innocent souls, and a Platypus to the RNG. Such offerings should appease it.
