This comp focuses on Draven as the main carry and uses the Legionnaire trait to buff him up. Knights are the preferred frontline choice with 2 units, but you can use just about any frontline you can get ahold of.
Go for this comp if you have good Draven items and a strong start with Legionnaire units.

Stage 2
Before Krugs
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.
Stage 3
Before Wolves
At Round 2, level up to 6 regardless of your start. Put together the strongest team you can.
Stage 4
Before Raptors
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.
Legionnaires are easy to build around with Kalista and Aatrox. You can put Leona and another Redeemed unit as a strong early game.
In the mid game, simply look to add in more Legionnaires to buff up Kalista who can act as your item holder before Draven. You can also replace your Redeemed unit with a Knight.
Even though Kayle is a strong 5-cost unit, this comp doesn't look to stall like other Kayle comps. You can still itemize Kayle with extra items for more damage, but it won't be as strong unless you have Kayle 2 star.
