Sorry to inform you but that guide doesn't exist and if it did it wouldn't work or else everyone would be 1500+.
Here are some tips though.
1) Learn to play every role (carry, support, ap, jungle) but specialize in 1. Kog took me from 900 to 1500.
2) always have a positive attitude and don't talk **** to others. If you get pissed or yell at someone on your team the only thing that does is make them play worse.
3) you will lose games, its impossible to win every game. You will get the short end of the stick sometimes.
4) counters are nice......if you know how to play that character, if not just play your atrengths. So many times have I seen someone fail trying to counterpick because they arwnt as good.with.that champ.
