Black Hole (Black Hole)

From Blaseball Wiki

Black Hole (Black Hole) is a weather condition first seen after Season 24's Earlsiesta as a result of the Supernova collapsing due to intensifying Riffs. The weather has only been encountered as an outcome of Jazz, though a very likely one.

Under Black Hole (Black Hole) weather, if a team collects 10 runs, the Black Hole (Black Hole) will swallow the runs (similarly to Black Hole weather), become agitated, and nullify a league modification.
