Notes:

Reupload because of stupid mistake.
The reason I put Blissey next to Zapdos is because all this changes affect the (mega) evolutions as well.

Did you know that when you use Seismic Toss with level 100 Mega Kangaskhan, you always do 200 HP damage and 2HKO everything that has below 401 HP or is a ghost type?
Now you can get your chance to try it out unless you transfered one from Emerald.
