Chen Gong Blow Up Everybody! | [FGO NA] Christmas 5 Rerun Challenge Quest

No Astolfo this time around. As you can tell, Chloe was supposed to deal with Chacha, but I saw Chen Gong was at 90% and couldn't help myself. If it was an art buffer instead of her, Gong could probably finish it the next turn, which means the optimal run for this comp is 4 turns after all.
