I want to be a meta slave

Guys I'm currently gold 3 with 55% win rate and I'm climbing to plat. I want to know the current meta champs so I can accelerate the process since my mains are not currently strong ( ezreal, jhin, jinx ). I tried playing draven and I have a 80% win rate with him since he is very strong at the moment but I dont like twitch who is another strong pick right now. I need champs for top and mid too.

I need the strongest meta builds and champs right now because my unorthodox champs and builds can only take me so far. P.S I dont have a hard time climbing I just want to do it faster and preferably this week. I want to be platinum by sunday so I need the broken champs right now.
