Eruption

"Eruption" (噴火Funka) is a keyword exclusive to the Kagero clan, and introduced in SS Trial Deck 05: Dragon of the Blazing Core.

How it Works
An "Eruption" ability forces any (RC) circle chosen to force all rear-guards to be retired and prevent the user from calling any units to the erupted (RC) until end of the next end phase, acting as a pseudo-lock.
