A-tier Patch 9.15 Comp: Imperial Guard
It will take some time to fully built this comp but once you finalize this comp with Imperial buff, nobody can stop your Draven and your hearty fronline will start melting enemy frontlines in no time. You can consider going for this build if you get very early 2 star Darius and good items for Draven (lots of Recurve Bows) In early game, all you really have to pay attention to is to get the Garius combo. You can use any third or fourth unit that's strong enough to let you survive into mid game without taking to much damage. In mid game, you want to start focusing on building a strong front line and get Draven on board. Until you get all 4 guardians and imperials, you can run 4 brawlers if you have'em. Sejuani will make a great addition to your team.
-Do not obsess with only having 4 imperials. You can instead run 2 brawlers or 2 blademasters until you finally find Swain. -Your key units are only available in late game so you'll have to wait out the game and level up then roll to get this comp on board. -In the early game, it doesn't matter whom you run. However, since you are only looking items that are good for Draven, you might wanna run Vayne or Tristana who carry Draven items in the meantime. Your carries are: Draven: Guinsoo's Ragebalde, Rapid Firecannon, Bloodthirster Swain: Dragon's Claw
