After a long time, (about six days...) I finally got a Chansey on LeafGreen. However it did not have the right nature. Since I don't want to spend that much time trying to get one with the right nature. I decided to make due with this one.
What I was trying to go for: (Taken from Smogon University)
Blissey @ Leftover
Bold - Natural Cure
204 HP / 252 Defense / 52 Special Attack
Thunder Wave / Toxic
Softboiled / Wish
The Chansey I have instead has a Hardy nature. While that doesn't cause any stats increase or decreases, I'm concerned. Should I train this one with the EV's & moveset provided, or do I need to make some slight adjustments to compensate her nature?
