Augments
Prefer augments which give a massive amount of items! Since you have so many carries in this comp. (Corki,Shen,Riven)
Need to know because how OP Emblem is at this set, emblem itself is equal to and better than items, so emblem augment is even better.
Best augments:
Silver:
Carve a path
Item Grab Bag
Silver Spoon
Gold:
Big Grab Bag
SwordSmith
Sunfire Board
Prismatic:
Sword Overflow
The Trait Tree
Golden Gamble
Items
Shen items can be very flexible, tank items and AP items are both good.
Riven items is even more flexible, she is even great with TG, but make sure you give her at least one survival item such as Sterak's Cage or Edge of Night.
Because how flexible you are with items, you should slam items to win streak early, level up aggressively and play the strongest board.
Carousel Rounds
Most preferable component: Sword, Belt, Crit Gloves
Carry Items
Core Corki items: Death Blade, LW
- LW is THE most important item since tanks have a lot of armor at this meta.
- LW on Corki is much more stable than shroud on frontline.
- Then after it's best to have either: Blue Buff or Shojin.
- So your BiS (best in slot) is either: DB, LW, BB or DB, LW, Shojin.
- Flexible items: Striker's Flail, Giantslayer
- Those are not the best, but acceptable.
Alternative Items

Gameplay
Most units can be rolled out and pick up on Lv8 instead of keeping on your bench.
But playing from Milio carry or Caitlyn carry is the easiest. However you should look for the strongest board possible.
Only level up to 8 at 4-2 ideally, since this comp is a 4 cost comp, rolling too early would be hard to pick up your champions from a larger uncleaned pool.
