The combo is 2x Sorcerer’s Apprentice + 2x Molten Reflection + Antonidas.
To play all of them on the same turn, you need to hit Emperor Thaurissan discount on at least four combo pieces. Then you drop 2x Apprentice, Molten Reflection on one Apprentice, drop Antonidas, Molten Reflection again and now you have four of them on the board and a first Fireball in your hand. Now you start flinging free Fireballs.
