Tier Listing

Hello,
I'm not sure if this is the correct place to post this, so if it's wrong sorry! :x
I am after a Tier List for Gen VII, but I only want it to include Gen I and II Pokemon. I have searched around online and I can't really find anything too concrete for one, but if anyone could help it would be muchly appreciated :D

I don't think something that specific exists/is easy to find, so I'll just look at the tiers and manually type a list out for you here with just the Gen 1+2 Pokemon. Will include Megas and Alolan forms.
