Play mainly safe until level 6. On levels 1 and 2, focus on auto-attacking the wave. Use your abilities for poking the enemy midlaner. You have the ability to shove in most midlaners with the wave clear provided by your Q, but remember that shoving leaves you vulnerable. You do not want to push the wave near their turret as you will be susceptible to ganks. Orb of Deception has little damage early on, so freezing is the most important thing you can do. Try to pull the wave closer to your tower and communicate with your jungler to get an early game kill. This is necessary, as Ahri scales better if she builds her core item as fast as possible. Charm the enemy midlaner to your tower and let him get a few hits from it. This will either transition from your jungler ganking and killing the midlaner or them losing summoner spells, so they will be in trouble next time. When the midlaner has a Cleanse, try to remove that spell first by taunting with a Charm and then disengaging after he uses his Cleanse. When an opportunity arises and he has low HP, all-in him with your Ignite and your other combos. When you reach level 6, you will be able to bring more pressure all over the map.
