If you want to be a nerd.
Hatch eggs, a lot of eggs. Raid, lots of raids: then
Ignore anything that is under top tier "amazing" and which does not have at least one top tier ability (max). Trash everything else
Then use the IV calculator.
Only spend dust on 95%
I trash anything with a 12 IV or lower on any ability unless super rare mongy
I use the following method to name IV
A=15
B=14
C=13
D=12
E=11
F=10
9=9
etc
so ABB = 15/14/14
or 9AC = 9/15/13
ow and 100 = 15/15/15
