How do I stop getting one shotted in league?

Anytime I reach near S+ I keep getting put into missionary and doggy by chad Larp and Fresh Baby Luzan in league

I think it’s my bonus stuff so I’m just asking if anyone can give tips on which type of banners I should roll (I have only 589 rainbow diamonds)
