How to get better rank!

i just found my true hyper carry mains! if you want to climb in any game you have to choose what item or champs you gonna main! and my mains that actually helps me climb without notice is actually: Kog'Maw at adc top and mid. Rengar at jungle and top. Fiora at top or mid. Hecarim jungle and for the last champ it is Ekko! a real pain in the ass at all lane except adc tho! this is my freelo champs and from now on im gonna tryhard my ass off and get what im playing for! diamond!!!!!
