Darius tends to be VERY aggressive. Give up CS and don't push. Farm under tower. What is good about this matchup is that, if he makes a mistake. You can punish him HARD. And they tend to misposition a lot.

Immobile and weak early, you can abuse his bad early game and can easily dodge his Q with your Q. He can set up ganks tho, so watch for the jungle.

Can pretty much block your mobility and her DPS is pretty good. Dodge or rush Tiamat to push and roam. Rush Adaptive Helm after Triforce.

Skill matchup if she is not running Grasp, hard matchup if she does. W her stun and just trade when you have health advantage.

Skillshot reliant. Still, if he ever hits something that is not his stun, he can stun you easily and you are pretty much dead. Rush Wit's End and abuse his early game so you can outscale him.

Avoid his stars with Q setups and you are good to win the trade, just watch out for his ult. Rush Tiamat and push, as he will most likely roam a lot.

Don't get stunned, and you are good to abuse Anivia. Rush Wit's End to counter her magic damage and to add DPS and extra sustain.

Her passive and R pretty much is anti-mobility. She has damage reduction and can abuse the fact that you have no damage reduction for magic damage aside for your MR. Try to snowball pre level 6.

You counter her with your mobility. If you have ult up, you are a threat to her. If you use her minions while you are dueling her, there´s a high probability that her tentacles will not even touch you.

Hybrid damage. She has insane damage, but she is still an assassin, and not a pure magic one. You can still win this matchup with outplay potential. She can easily abuse you in lane however.

W nerfs made the Ahri matchup pretty bad. You rely on your MR in order to not be popped up by her. Abuse of Ahri each time she misses her charm, however. Rush Wit's End.

Avoid his Qs and you are gucci. His CC is pretty unreliable and easily countered by your mobility. Make sure to E him if he is about to die and uses ult, so you can mark him and burst him. He no longer revives so if you win the trade, you win the game.

Bullshit matchup. He is stronger than you on dueling, he is stronger on splitpushing and will mop you on lane. Pray that he is bad. Focus heavily on teamfighting and relying on your team. Or simply dodge.

Ahri Ok In 5v5, Ahri can dive to your ult and take out the priority targets along with you.

Orianna Ideal Ult if Orianna ults and catches the entire team. She can also protect you and add extra durability with her ball. When you dive into the enemy team, she can E > R and it will win the teamfight.

Sion Ideal Can lock down entire teams pretty well, enabling them you to ult them.

Miss Fortune Strong Most of the synergies I have mentioned are mostly utility champions who use their CC in teamfights to enable you, however, Miss Fortune is maybe the only ADC that you synergize with. Both her ult and your ult done together will force the enemy to, either burn summoners or eat all the damage.

Nami Ideal Her CC is enough for you to keep sticking to the target. She also keeps you alive and empowers your damage. She is an ideal support for when you want to make dem zik playz.

Janna Ideal Adds AD, which means more magic damage from your passive, shields you, disengages if they try to ambush you, etc.

Kai'Sa Ok If you E someone, she can follow you up if she is near. Kai'Sa is a champion that will be more than glad to take out the enemy team and their backline. However, you still might need to peel for her if she mispositions. Kai'Sa and Irelia alone aren't good, but with a good tank like Sion, Leona, or Malphite can make it effective to dive on.

Blitzcrank Strong You want to dive into the backline, not for the backline to come with you. Irelia benefits from Blitzcrank the same as any other champion. However, he can pull a support or peeler so you can take out the backline rather quick.

Ashe Strong Ashe with Runaan's and her slows have good AoE damage and CC. Enough utility for you to remain sticky to squishier and tanks alike.

Illaoi Ideal Your ultimate, if placed inside the entire enemy team, can set up the enough zoning for Illaoi to be effective on her ult. Almost guaranteed won team fights.

Zilean Ideal Revives you, can use you as a way to damage the backline with his bombs, can make you faster in case the enemy flashes, and can revive you without burning out Guardian Angel. Zilean is the ideal support you want to look for.

Yuumi Ideal Protects and heals you while you dive, ALSO her ult can set up your ult and team fight. Make sure to have Yuumi linked to you if you are ahead. Yuumi is the best support you can go botlane with.

Syndra Ideal You no longer can W magic damage, so if Syndra oneshots the mage, you are good to go to clean up the rest. This alone makes her synergy with Irelia more than ideal. If she W's and stuns the entire team, you can just clean everything up too.

Amumu Ideal Need to say more? His Ult is basically sooo good with your ult and your E.

Morgana Ideal Can Q a priority target so you can begin your dive. Also, she will benefit a lot from your zoning with her ult and her AoE damage. Also can shield you against magic damage, which you're weaker against.

Lux Strong Lower syngergy than Morg, but still can shield you, CC and provide good AoE damage.
