Hi I am ZealousBliksem and I just got placed in P3 but I am looking for diamond this year.
Throughout my ranked career I have always played Orianna and enjoyed playing her a lot.
Orianna is a mage whom if played properly can destroy teams. Her teamfighting and kiting is amazing and I personally am in love with her. She is viable in every stage of the game and can destroy, if properly played, any matchup. It does take a lot of practice to get used to her mechanics and positioning but it is all worth it.

I like to take Aery because it just fits with her kit. Aery can be used offensive as well as defensive which makes it perfect for Orianna. Take Ultimate Hat for her biggest playmaking ability: Shockwave. I like to take Transcendence for that extra cdr which is very important for Ori because cdr helps her move around her ball faster. Last I take Gathering Storm for that extra power throughout the game, you can switch this out for Scorch for extra laning strength. As my second runes I take Cheap Shot which goes great with her ultimate and Eyeball Collection for even more AP ;).

Level 1 u can choose between Q or E depending on the matchup, I tend to take Q to get that fast push going. Always max Q first, then W, then E and always max ur ultimate when possible.

Always take FLASH!!! Ur a mage and u need that mobility of flash. As my second spell I often take barrier. Barrier allows you stay alive longer and is better than heal in my oppinion, heal gets countered hard by ignite. Ghost is also very viable for ori, this allows you to kite or chase better.

-Very good teamfighting
-Good kiting
-Strong throughout the game
-U can play different playstyles

-Very immobile
-If fallen behind hard to come back
-Takes time to learn
