To handle a champion on a new way that is diffrent is for the most guys a trap for me i play lulu very easy and dominate very easy with this setup =). Trinity force helps you to dominate early Laning Phase very Well gives you all what you need a good movement and some Ablity Haste. The Synergie between this items Stuff is the Rune Setup. Eletroqute scales with AP + AD. After a strong early fase with Trinity Lulu starts to struggle in mid Fase a bit because her DMG Scalling isnt that well. But you can get pretty cancer and very deadly over time and your not attractive couse you cant be oneshottet for example the acutaly assassin meta ^^. You scale Movement, Antiheal, Ability haste, but at first you need items to dominate laning phase ez. Trinity is the allround package for Lulu to be very cancer and with edge of night you have also for lategame the pressence with some Lethality to stay strogn and colloect something like 15/3/20 kda ina matchup. The Synergie is about the small amount of ap that you get from morello to scale your ultimte and trigger yourself into a HP MOnster that sucks enemys with polymorphe, that you will upgrade for endgames. Triity force + edge help you to kill enemys ez, Morello + cosmic drive give you the amount of hp and cdr together you will need and also at least you have with trinity + cosmic a good movement to be cancer, Eletroqute helps you to deal enough dmg and scale with ad + ap and also at least spirit visage burst lulu quit good and tanky ^-^ with Ravenous hunter that just heal with your scaling dmg.

So have fun.

If you might be would read my notes you would understand it already ;)

What's with the two AD items and two AP, I don't see much synergy, how does it work well? I think I fell into your troll trap...
