4 Deadeye: Aphelios/Ashe/Akshan/Urgot
Utility: Lissandra (gives Freljord/Invoker
Carry Items: Rageblade/DB > IE/GS/RH/GuardBreaker
Tank Sejuani

There are many teambuilder websites that let you theorycraft, the images make things take up too much space so I like to make my own notes I can reference in game so I can see details of all 4 comps on the 1 screen. That said, here is Robin's sample Azir board, this is the kind of thing we're going off of to create this text:
