I will try to write beyond obvious and crap tips i find like "don't die", "play safe", "dodge that skill", "pick that champion", "dodge this match up", "ban this champion"

Ahri:

• She is only strong when she hit the charm
• Start juking and expecting for charm when she is near you, most ahri players won't try to charm at long range

Akali:

• Its almost impossible to fight her in the shroud
• Exaust can buy time for you to get you far away from her shroud
• expect a all-in at lvl 6

Anivia:

• In the late game her strong kiting AP tank makes her a living nightmare to any low range champions, even champions like zac and J4 struggles to take her out without follow up
• Well timed crowd control can cancel her ultimate at important times

Annie:

• Don't enter her range, she can easily 100-0 any squishy in a single stun
• If you Shove the wave hard she will have less control when her stun is stacked

Asol:

• Open for suggestions

Azir:

• Mind his Q, it has a very high CD at lvl 1 and without it Azir has very offensive and defensive options

Cassiopeia

• Becarefull on short trades, cassiopeia players rarely back off
• Without poison she does basicly no damage, so pay attention to her Q, consider bringing ghost and going boots first to help you dodge it

Corki

• Play a very aggressively in the early game

Diana

• Her high burst weak desengage makes her extremelly vunarable against exaust

Ekko

• Very low kill treat in the lane phase if you doesn't get hit twice by his Q, stay away from your minions or he will push the wave and cause damage to you
• Pay attention to where his R, it can deal a lot of damage and its easy to avoid

Fizz

• Don't build banshee, you will rarely have shield when he engages.
• Zhonias, can counter his E and max range R, limit him into engaging you with Q, this drasticly increase your outplay potential.
• He needs at least 2 out of 3 of his damage abilities to kill you and all of then have their own problem in using then, he need melee range to use his W, he become out of escapes without E, R on max range can miss and R on low damage can cause not enough damage
• expect all-in lvl 3

Galio

• Open for suggestions

Irelia

• Mind the amount of minions who are low, is she gets 4 stacks she will rack and slash you even without stuning
• If consider getting exaust to buy precious time to her in a fight
• expect a all-in at lvl 6

Jayce

• Just don't get poked by EQ
• that is it

Kassadin

• Allways counter pick him if he blinded kassadin, this will get you a very strong edge over him
• do a lot of roaming independent if you are playing a scaling mage or a melee AD
• Any champion can beat him before lvl 6

Katarina

• She will allways focus the easiest target to kill independent of kill priority
• If you are low health don't go to the fight, she will hit you and start the fight reseting
• She depends on stand still target to cause damage, flashing at the right time and staying far way from her daggers can drasticly reduce her damage

LeBlanc

• Open for suggestions

Lissandra

Lux

• Stay away from your minions or she will push the wave and cause damage to you
• Like Ahri Lux isn't really scary if she doesn't hit her Q

Neeko

• Like fizz, Zhonyas his really disruptive against her damage output
• Allways time her flash(Time when she flashes 5 min), she will do a lot of agressive flashes
• stay away from your minions

Orianna

• Don't be near her ball
• the engage champion will have the ball 90% of the time

Pantheon

• All his 3 abilities are important for trading, play agressive if he is using then to push the wave
• A ward in the middle will help you control his roaming

Qiyanna

• Low engage range for a assassin, expect a lot of flanks
• Without ult her damage potential is bad, stay away from walls

Ryze

• The only ablity that "has a cooldown" is his W

Sylas

• He pratically can't engage without E2
• Stronger against low health oponnents

Syndra

• Don't stay near your minions
• She is only vunrable against long range engages, flanks or facechecks otherwise just stay a screen away from her

Taliyah

• Open for suggestions

Talon

• Very low kill treat in lane if he doesn't land W twice
• A ward in the middle will help control his roaming
• Low engage range for a assassin, expect a lot of flanks

Twisted fate

• Mind dodging his W, without it he can't one shoot you from full health, he can combo it with everfrost or any other CC from his team

Vex

• Open to suggestions

Viktor

• Don't be near your minions

Vladimir

• The best time to trade with him is right when he is spend his empowered Q
• Pokes and all-in him is useless because of his sustain and W
• If teamfighting him is becoming impossible start split pushing to force him out

Xerath

• Stay away from your minions
• He is only vunrable against long range engages, flanks or facechecks otherwise just stay a screen away from him

Yasuo

• The only moment that he is strong in early game is when he has tornado, he is weak after he spend his tornado and when he came back to the lane
• stay a screen away from him if he has tornado
• engage range is low without minions
• He isn't strong on early game 2v2, 3v3 like he is on 1v1

Yone

• The only moment that he is strong in early game is when he has tornado, he is weak after he spend his tornado and when he came back to the lane
• Stay a screen away if he has tornado
• Exaust is extremelly disruptive against his all-ins
• Unlike yasuo his engage range is stupidly high
• He isn't strong on early game 2v2, 3v3 like he is on 1v1

Zed

• He will allways reapear at the oposite side that he ults, example: he ults from the south this means that he will reapear at north, this makes him vulnarable to skill shoot right after he reapear
• Allways stay full health against him in the lane phase recall and losse minions if needed, in the early game he doesn't have enough damage to 100-0 you
• Extremelly realiant on his ultimate to score kills, if he doesn't ult you, he won't be able to kill you

Ziggs

• Open for suggestions

Zoe

• Like Ahri she does nothing unless she lands her E
• Her ult makes her predictable for a skill shoot
