Reverb
Everybody do the wave lol 🌊
Reverb is a weather event first observed at the beginning of Season 5. It refers to the residual effects of The Wave crashing over the League.
It's been reported that Feedback from Season 4 grew and grew to the breaking point, "resulting in a tsunami of quantum Waves that appeared to completely obliterate and reconstruct everything that is and ever will be." [2]
While a Game experiences Reverb, there's a chance for either team to have the positions of their players completely shuffled around. For instance, this may make a batter into a pitcher, or vice-versa.
Reverb shuffles were first recorded on Season 5, Day 5, when the Hawaii Fridays had their roster shuffled while playing a game against the Yellowstone Magic.
History
All known instances of reverb shuffles are documented in each Season article.
