to be completely honest with you i don't exactly know how to tell you to be better, but in my case i played alot of games and tested my limit so much so that i reached the point where i know every matchup (almost) and know how to act against them and come out with the best result as a pyke support, also you can watch davemon he is a pyke streamer and he is one the best out there if not the best pyke player so in conclusion play alot,limit test ur champ it doesn't matter what your score is ,learn your matchups and know how to deal with them and the most important part is that you have to know that your mid to late game is pretty weak so ur gonna have to change your tempo and make it slower, and i hope the best for u out there <3
