Well for one thing, riot is making 1 tricking less viable. So you're not going to see much of an increase from the average win rate, than if you had half of the experience on the champion. Just become proficient at a few champions who cover each other's weaknesses, and take which ever the enemy is least prepared to deal with.
Though, besides extensively more practice than you, he doesn't play in the moment. He plays ahead, constantly. He plans his reactions in advance, factoring in as many possible details and as many moves ahead as he can, before the context and circumstance of the game change, and the planning restarts. To do this however would require your mechanical skill, in respect to things like last hitting, wave control, and ability CDs, to be so refined that you can pass it to your subconscious. So despite all of what i just said, DON'T TRY AND DO THIS.
As you said, you're gold 3. If you want to rank up, then you're asking the wrong question. You shouldn't be concerned with what makes faker good. If you want to rank up and get better.
You should be asking, "what is the primary difference between yourself and the average plat player?" This will allow you to get better.
Something else to ask is, "what's the difference between the average gold player and the average plat player?" Then exploit that difference.
Once you get to plat, ask yourself the same for diamond, Exc.
Oh, and a mean little psychological trick to make your opponent actually play worse, is to ask them to explain how the did something which seemed well executed. Generally if someone's actions seem rehearsed, then they are doing them subconsciously, and asking them to explain how they did it brings it out of their subconscious and make it harder for them to repeat. It's like when you think about your breathing pattern.... yes, it's that exact same phenomenon.
(Also, harder to read text makes you think about it more ;D )
