I will tell you about bLiSsY
First go into the safari games and get yourself a chansey.If you can be bothered try get it a bold or careful nature or somthing.Then when you got your chansey.Go to the second city and when you cut the tree go to the back of the museam and talk to one of the guys and he will teach you thunderwave i think (maybe counter) Then you go to this guy in the biggest town and he gives you either counter or thunderwave.If you want an aromatherapy blissy you will have to bred your blissy with a rosela.
I know this is very helpful but i couldnt be bothered searching up to get the correct places and stuff.
