Shurima is a pretty straight forward setup. Similar to Strategist your core revolves around Nasus as your main tank and Azir as your main carry. This comp prefers to rush for a quick Level 7 and roll for Tier 4 units to stabilize. Afterwards you can push towards Level 8 to add Aatrox/Jarvan.
9 Shurima is a difficult trait to reach, but worth going for as a win condition if the game allows it. You can also open with Shurima Emblem from Urf Legend and give the Emblem to Jarvan/Aatrox to help you stabilize in mid/late game.
