Level up to 4 early if you want to start a win streak. Level up to 5 to try and continue the streak.
If you're weak in the early game, you can opt to save gold and lose streak instead.
At Round 2, level up to 6 regardless of your start. Put together the strongest team you can.
At Round 1, level up to 7. Roll down to stabilize your comp if you are weak. Afterward, save up to hit level 8 and complete your comp.
Use the early game Sentinels and use extra team space to complete another trait or simply add in an upgraded unit.
In the mid game, you can start transitioning into utility units like Mystics, or you can simply look for 6 Sentinels for a small power spike when finding Lucian. You can also use Tristana as a mid game Cannoneer to hold items for Lucian.
You can play this comp similar to a vertical Lucian comp that uses 6 Sentinels. However, once the late game starts, begin looking for stronger units like Gwen and Mystics to replace some of your weaker Sentinels.
