The definition of "tails" can be rather loose, for example hydrapple can count as having two tails. Please tell me the number of tails for the Pokemon and not just the names, thanks.
Idk what to put for tags and it needs one, so I put gen 9
Clear Cut
Multiple Pokemon in one
Unsure going off of Bulbapedia
I believe I have all of them, but let me know if I somehow missed one. Hope this helps!
