Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
idk I'd have to have something to work with. You just said "idk", which really doesn't leave much to comment on.
What I did was think to myself:
"what makes a pokemon good in asb?"
"how many of those things does [pokemon] have?"
"what things would be mediocre on a normal mon but are great on [pokemon]?"
further things to think about include:
"what specific ability/move/type/stat synergies make [pokemon] a pain in the ass?"
"what would I sub for against [pokemon?]"
"how many of my mons can beat [pokemon], and why can't my other mons beat it?"
