First thing is to find a duo that you can climb with. Based on your op.gg you don't duo with anyone around your elo. Try to identify someone that is good and willing to duo with you. Soure: http://na.op.gg/summoner/userName=Kewlipo
step 1 After a game, look at their op.gg and inquire about them duoing if you think they will be a good fit to climb with.
Step two, use discord(any other voice comm program works also and wreck some boosted plebs that can't communicate. Also it goes without saying practically that if you duo your chances of getting bad teammates is reduced and you have someone you have experience with to help carry a lane. I would recommed, jungler or adc. Mid/support is usually not prefered since you can gank mid to help since I assume you are topping with yasuo. They can control one side of the map and you the other to put it bluntly.
Step three evaluate your duo and if it doesn't work become a douche nozzle and drop them like hot garbage and find someone else if you think they are dragging their weight. Try to be nice to them, you are the douche in the situation for baiting and switching them just so you can climb. Do it with tact and be as nice as possible while you are telling them you just want to be friends (this goes for boyfriends/ girlfriends too, but make sure no sharp objects are around to cut your pretty face with.(trust me things get messy fast))
repeat steps 1 and 3 endlessly, you can never have enough good players on your friends list(unless you reach cap then you're shit out of luck, idk i have hardly no friends and hate people too much )
Optional steps from here on,
Step four, learn matchups op.gg/league of graphs is a good starting point. Then learn at least one champ other than yasuo for god's sake, idc what it is but you won't win or move up unless your champ is op and right now yasuo just came off nerfs. Learn riven, fiora, irelia i really don't give a f but find something that you can also learn so you can win matchups and not pick yasuo into someone you know you are gonna have problems with.
Step 5 replay.gg, if you don't use this or the new tool then you need to. There is always something YOU can do to help the monkeys on your team. Scarra, and a lot of pros do this. Best thing to realize where you are making mistakes. Also watch n3acy if you need to learn how to analyze your replays. But short explanation is look at what you are doing to help others/take objectives and where you are failing and for what reasons. Did you get greedy? Did you overstay? Did you not gank other lanes to help them (if you think you could)? These are questions to ask yourself when looking at replays and even after you died in game.
Step 6 start a discord server and try to get your diamond retard teamates in before the game, if they don't want to be in call then its their stupidity not yours. With a discord server you can give web browser link so you guys can say stuff instantly. Trying is better than having to type out everything yourself. Even if you get one person else in the call of the 3 to 4 you don't know, its an advantage your enemy might not have. They don't have to have discord to use web link so make sure you use that.
Step 7 use op.gg before a match, identify what the weakest members might be then try to apply pressure to their weakest link. Also bm the weak link if possible to tilt , just don't do it so much that you are in risk of chat restricts. Question marks and t(-_-)t, cy@ usually work after your kill them. This will demoralize them and is good if they are as easily triggered as your teammates. This one is kinda in a gray area but definitely works if you can trigger an enemy player into raging or even in the best case scenarios tilting, or make them so mad they start to feed. Just be careful with this trick as it is like playing with fire, you can and will get burned if you get too close. IF YOU GET A CHAT BAN BECAUSE OF THIS STOP IMMEDIATELY OR YOU WILL EVENTUALLY GET TWO WEEK BAN AND IF YOU CONTINUE YOU CAN GET PERMA'ed if you do it with no tact and carelessly.
Step 8 DISNEY MUSIC, but seriously try to find an anti tilt music or method to stop rage or tilting. Usually listen or do it after the game but as long as you keep the music low won't affect your game play since you can still hear pings which i advise turning to high volume so you can know right away and not misanything your teammates not in comms are trying to tell you.
BONUS TIP
You can fuc up your hands gaming btw and its not fun once the pain starts. Some people get hand injury's since they don't take breaks ever. Don't fuc up your hands and detilt a little of your game ever couple matches. Here are some hand exercises that help you not get vice grip hands and makes your hands feel better after playing for awhile.Also try these if you get a cramp or something feels off with your hands(you'll know what i mean if you ever felt it) https://www.youtube.com/watch?v=EiRC80FJbHU
DISCLAIMER
If you want to call me a scrub that is fine idgaf, I play dota 2 and league of legends at high mmr anyway so I really could care less. I tried lower priority queue in dota 2 and anything you say here is childs play to what the trolls do in there, IT IS LITERAL TROLL HELL and i learned to never dodge games/how to deal with troll talk because of this hell that is like dante's inferno in reverse.
I'm not really gonna say shit after this unless someone asks a legitimate question. I just use two burners to talk anyway and not gonna put any of my valuable mains and smurfs at risk, because I like to say what I want when i want and not risk shit.
Also bonus upvote to anyone that can name where my name(IGN) comes from.
