Final Comp
Rolling
With rolling on Hyper Roll, since levelling up is not a concern as you level up after a certain amount of turns, playing econ with your gold is not super important. However, you want to try and roll really quickly at the start and secure the cheap Demacians as they're popular for early game wins. Throughout the rest of the game, the goal is to just star up as many of your champions as you can.
Early Game
Mid Game
Champion Items
Quinn: Infinity Edge and Last Whiper is the most important item for Quinn (because of the Demacia origin, Quinn will equip a radiant Deathblade to complete her item set).
Kayle: Guinsoo's Rageblade will act as a backrow carry with Quinn while the fighters in the front lines melt the opponent's build.
Jarvan IV | Galio | Sejuani: Warmog's Armour will grant health to tank most of the damage from the opponent's team while our back carries and AD fighters attack without too much issue.
Mordekaiser | Aatrox: These two hardcore carries can use the same items between the two if you cannot duplicate the items to use on both. Aatrox will be the main backup if your opponent is battling this comp well.
Rek'Sai | Qiyana: These AD fighters can also share their items, however try and complete a set of items on Qiyana as she is easier to 3-star than Rek'Sai.
