How to deal with Azir as Nasus?

Options during laning phase:

• Max E for waveclear and poke (building any AP is optional)
• Build MR to survive the laning phase and take what farm you can
• Lane-swap with your mid-laner (since they are likely better equipped to handle Azir)
• Call your jungler up for a gank since Azir will likely be overextended and harassing you under your tower

Options after laning phase:

• Avoid him during fights unless he leaves himself open.
• Split-push

if you have and some other mr then just bum rush him wither recks him

I honestly don't think you can without using ghost or flash. Nasus is weak to kiting and that's what azirs kit does.
