[14.2] Lulu Army

You might have expected it, but Lulu has been buffed recently. Not only does her spell deal slightly more damage, but Hyperpop has been buffed as well. The cherry on top is that Hyperpop can buff other Hyperpop units. Thus, placing Lulu copies near each other will lead them to fill each other's mana and grant each other Attack speed, creating a casting loop. When we add Spellweaver's AP stacking, it can make them reach a very good amount despite still being in 3 Spellweaver.

If you've got Hyperpop Lulu, you can stay at 3 Spellweaver, but make sure to have good defensive items on both Ekko and Neeko. If they fall, your backline will follow them very fast. Of course, when you've got a Ziggs, adding him will provide a good boost, since he'll make the Hyperpop bonus better and will debuff the magic resistance of enemies hit by his bombs.

If you've got Spellweaver Lulu, you can add Gragas and later Illaoi to get a better frontline. You'll be at 5 Spellweaver, granting a better base AP as well as a stronger stacking.

Your Headliner Lulu will get a Shojin's Spear, but she has 40 max mana, so giving her a Blue buff will be very fine (and you can give Blue buffs to the other Lulu as well). Reducing your Lulus' max mana will prove very beneficial as they'll cast much more frequently. They will also enjoy Hextech Gunblades, keeping your frontline healthy.

Hologram will give you a free bonus Lulu with the same star level as your main one, though she won't be able to have items (but if you have enough Lulus near this one, this won't be too much of a problem). Talent Search will give all your units their Headliner bonus, including the Lulu soldiers. On the same logic, New Recruit will give you one more unit slot to bring in a Lulu.

Cybernetic Bulk, and Vampirism are very good augments overall, and since we'll play with K/DA, that will be a good combo. Do It for the Fans will help keep the frontline healthy too, since 3 out of 4 frontline units will be Superfans. Healing Orbs will also make the fights last longer, while Cybernetic Uplink will both make your team slightly bulkier but also make your Lulus even faster at casting.

Buried Treasures and Spoils of War will give you more resources to look for your items and units. I'd recommend against Spoils of War II, as it has barely 5% chance more than Spoils of War I, so if you've got another of those augments, leave SoW II aside.

Combat Caster isn't a choice you'd want to prioritize, but if worse comes to worst, it might help protect your Lulus who'll refresh the shield at a very fast pace.

Finally, Trade Sector is always useful when playing a reroll comp, and Return on Investment will give you a free Tactician's Crown once you've rolled your shop 16 times after picking the augment. Make sure to have a decent gold reserve before picking it, though. You won't want to pick an augment that needs you to spend 32 gold on rolls (not even counting buying the units) if you've got barely 20 when picking it.
