1- Play Simulacrum x2 on both Sorcerer's Apprentice + Leyline Manipulator = 3 + 3 + 4 mana

2- Next turn, new Sorcerer's Apprentice cost is 0 mana, then you can play Archmage Antonidas and infinite Fireball if you copy one of the Sorcerer's Apprentice with Molten Reflection. So you have 4 Sorcerer's Apprentice that cost 0+0+2+1=3 mana and play Archmage Antonidas in the same turn (7 mana).

Probably the draw that Aluneth provides is enough, but it could be added more with Coldlight Oracle, Novice Engineer, Loot Hoarder or Acolyte of Pain. Also wanted to keep the freeze+Doomsayer package in the list.

I'm not that sure if that reachs the OTK before the quest does, but I will give it a try.
