“Almost impossible to kill her if she's good. You will just get hard poked early and she will have perma prio while you cant go for the cs, especially if she has barrier/exhaust too its hard to all in her. Ori's biggest weakest is probably ganks and if your jungler can force a 2v2 or gank mid and you can grab kills and snowball hard. If you get a lead she will be useless and can be oneshot for the rest of the game. Never go for an extended trade with an Orianna! Go in and out because of her passive aa's so keep it short always in lane or just dont go for trades at all which is the more safe option. ”
“Probably one of the most even matchups Yasuo has. Let the wave push to you early and don't let her poke you down since her Q autos hurt a lot for a mage. Go on her when she uses her Q on the wave bc it has a decent cd early on. Use windwall in between her and where her ball is so you can block her E and deny her the shield and you should always win the trade. Dodging her ulti is pretty easy as long as you don't stand in the same spot and keep dashing around or dash into her when the ball is on her.”
“Keep your eyes on the ball, she relies on people not paying attention to it to deal damage way more than you think. While still dangerous in the late-game, she's generally not nearly as powerful without her ulti, so try to make your move if she misses it or wastes it.”
“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.”
“Start Doran + 2 Pots if 1) You think you can outplay her and hit your W's to generate a kill at levels 3-5 or 2) You think she will burst you down post 6 (get an extra ring).
Start Corrupting if you think you will not hit your W's (or you will get poked down) and you rely more on wave clear/spammy poke (you will be way more squisher but more durable -- this is recommended if you are sure you will not get hit by CC spells and instantly die).
Can be a difficult matchup if the Orianna is really good. Look where the ball is and how long it takes for the ball to reach you and play accordingly. A good Orianna will play probably super aggressive while a not so good one will play passively and just farm up. Careful for her ult/flash ult as that can setup real easy ganks for their jungler. Careful on Q/E/W because her W movement speed can help her escape/dodge. Don't get poked down by autos and do smart trade proccing your rune as often as you can. Play with Ignite if you want to try to go for the kill or Heal if you feel you are going to get a bit overwhelmed. Heal also helps with ult-dodging because it gives you the movement speed that is necessary to get out of it (if you are quick enough).
As always: Roam!
In teamfights if you engage first and jump on top of her she will have a hard time adjusting her ult to hit 3-4 team members (which she WILL want every teamfight) -- Don't forget Zhonya's for these kind of engages!
Biscuits might also be useful.”
“She can actually do a lot of damage early game with auto/q harass, you'll actually be on the back foot until about level 7. Try not to stand near the 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 slightly better than hers.”
“Orianna is one of the hardest scaling champions in the game with great utility and early game.
You will outrange her early due to E range, but ultimately you are reliant on front to back as you will never ever 1v1 this champion without landing your full combo.
Play this as a scaling match up, take advantage of your early game priority to create a kill window on her or resolve yourself to max range casting from the mid game onwards for picks.
“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.
“Just land Q and proc eletrocute and get out with W, she can never trade back, always dies to a full all in lvl 6”
