“You want to wait choosing your first ability until you know what she started. If she started her shield, you want to start Q and shove her in. If she started Q and plays agressive, you can start E and go for early trades. This is a skill matchup that favors Orianna in the early laning phase. ”
“Fleet foot + resolve + doran's shield start should be enough to let you survive the early stages against her aggressive laning phase.
Her Q deals less damage when passing through targets so stay behind minions when trading. You can start trading back once you have level 3 but until that play it as passive as possible and make sure you don't get poked too much.
“Orianna will zone you a lot by using her ball, this will make it difficult for you to farm and very difficult for you to harass her.
Her (E) will absorb a lot of your damage in the early game laning phase. Be mindful of Orianna's AA as they can really hurt!”
“At level 1 I'll E-AA. After that, my Q-AA-E-AA-E/Q-E-AA-E-AA deals more damage than her Q-W-AA-AA and my shield is stronger, but it's harder for Lux to hit a Q than it is for Orianna - if I miss it, she'll zone me further away from the minions. She'll most likely keep her ball up in the lane to zone and this opens her up for E poke since she can't shield herself immediately. Later on she has enough damage and cooldowns to kill Lux and Lux can't kill her, so staying out of her Q range is the way to go. Also it's very important to ALWAYS keep track of her ball during teamfights.”
“You can kill her easily , she can poke you but that doesn't do anything against you , you just heal everything back from her or raptors, if you can you can kill her early if she lets you to poke her, also try to dodge her ball”
“She will poke you a lot since you are a short ranged champion and she has a lot of range. Her damage is also insane and she scales quite well. You can't ever get close to her if she plays properly so just try to farm and outroam her after level 6, since your waveclear is better than hers.”
“Can spell real trouble with you if you aren't careful enough. Orianna has ridiculous poke early game and she out ranges you too by far. farm play passive and all in her like most at 6 if you can and are confident.”
“Orianna will zone and bully you off your farm all lane long with her ball. Her shield makes her surprisingly tanky and couple this with the fact that most of them take barrier means your in for a difficult time when you try to burst her down. This is a dificult lane in the sense that it's hard for you to farm safely and even after level 6 you will likely find it difficult to 100-0 her. You can try to bait out her ulti by using (Q)+(W) and then using (E) to leap back to safety if she ulti's herself. She has no real escape so call for jungler help and don't forget to roam for kills whenever possible and look for picks on the map.”
“Try and avoid using your burst combo's on her whilst she has her E up, as she will then be able to Q.W and constantly beat you down with auto's. When you each hit level 6, try to force her to use her ultimate whilst you have W'ed in to her, this means you can instantly W back out when she uses it meaning an easy kill for you. Hitting your chains is pretty crucial at this point too, just to make sure you get some damage off onto her whilst trying to bait her ult.”
“You won't really be able to kill each other unless a jungler comes, so just focus on farming. ”
