That should be in the guide for RNG. I never heard anything about that.Wondercards have random natures unless that event can only be one nature.
So this means I can RNG a specific nature for the upcoming pichu and jirachi?
I feel sad now
Side question:
Do people have an easier time RNG egg IV on odd or even frames?
Because I noticed with I do a odd frame, the egg iv is right.
When I do even, the IVs are high but wrong.
