My Champion Pool Building Theory

Hi guys! I'm LvI 1 Bidoof

I have a theory about building your champion pools in ranked to get the most out of your matchups! Tell me what you think?

The Triple Threat Pool This theory is based around maining 1 champion, and have 2 side picks

Example- Bidoof I main (plz no hate) What else should I play? Looking at matchups, i decided that i should learn 2 other champions to benefit my fizz

1. A champion that counters fizz incase someone steals it! (this actually isnt great into fizz i just like the matchup so)

2. A champion that does well into fizz counters Champs like Brand can outrange and harass most of fizz's counters.

What does this mean? Essentially, I play fizz most of the time. If they blind pick something that Destroys fizz in lane , i will take my champion that is good into fizz counters . If they take fizz, i will play . If i pick before the other mid and my team wont trade OR they blind something that i can play fizz into, i take

Just something on how I play my champ pool. Thoughts?
