Seraph's Embrace supplies Mana for repeated Command casts and a shield under pressure, while Blackfire Torch adds burn to the ball's repeated area damage. Rabadon's Deathcap and Void Staff improve the AP and penetration of a Command: Shockwave sequence, and Zhonya's Hourglass is the sole active defensive tool. In the combo simulation, Arcane Comet triggers from the first ability hit and gives repeated poke the most reliable expected damage.
