Hero Summon: Summon the Darkin Sword Demon at the Beginning

[Synthetic flow + invincibility + summoning system + upgrade flow + no defeat] After switching to a professional summoner in the sewers, he awakened the summoner system, which allows him to contract heroes in Runeterra into summoned beasts. Is the summoner weak? That has nothing to do with me summoning the beast. At the beginning, summon the top laner Aatrox, the dark descendant sword demon of the Five Tigers, and do it! Genius is just the threshold for meeting me. For someone as good as you, I can fight ten!
