Sentinel Academy

Initial gameplan is to open with 3 Academy/2 Sentinel and use Lux as item dump until you find Heimerdinger. You want to rush for Level 8 and play 4 Sentinel / 3-4 Academy for midgame. AD items can go on Ezreal at the begining but should be transferred to Corki or Jayce once you find him.

Works best if you have a Sentinel Emblem so you can run 6 Sentinel early. Can also go deeper into Academy with Emblem or early Jayce.

Kill Streak Anomaly for Heimerdinger is very strong, but since you can't force it anymore you might have to settle for defensive Anomaly on Illaoi.
