Alright, so if I can't check the nature I'll have to know these things. It sucks, really.
Assuming that the Rayquaza has no EVs at Level 70, freshly caught, what are the stat values for each stat when they are at 31 neutrally and at a positive? I wish we had the kind of summary-surfing thing we had back in RSE, then I'd know for sure.
Also what is the stat value that will let me know I've definitely got a negative for Speed? I don't want to end up with something like a Quiet or Brave Nature :/
