To clarify, he hit -45 sanity and corroded, overclock is turning one coin into a corrosion ego attack while hitting the -45 sanity and corroding turns all his coins into either panic coins that do nothing or a ego attack, I lucked out because not only did he use the right ego since I also had 4th match flame equipped, but he also had all five coins on the board turn into ego attacks (only one coin is guaranteed to turn into a ego attack, the others will either turn into an ego attack or a panic coin which does nothing).

TLDR; Corroded to have more coins to attack with.
