Rule Changes
- At the beginning of Chapter 1, all players will be asked to select between special versions of , , , , , , or , exclusive to the mutator. Upon selection, the player's character will be replaced by their selection.
Notes
- Since the character is instantly replaced, the characters that players select during deck building are irrelevant in this mutator.
- After characters are swapped, all players' starting hands are reset with new cards from the deck.
- In this mutator, players will never start with a Hyper in their initial starting hand before character swap, since the deck does not contain any blank Hypers at the start of the game. It isn't until after the new character selection has been made (but before the new starting hands are determined) that blank Hypers are shuffled into the deck.
- The boss encounter is determined before characters are swapped. This means players who selected with a Poppo Event cosmetic during deck building will increase the odds of appearing as the boss by +25%.
- Players keep their starting Norma objective. This means players who selected during deck building will have a starting Norma of 1 Win, regardless of which character they end up controlling.
- After characters are swapped, the starting music is refreshed to correspond to the new character changes. If the current board has no field intro music, this means the theme will change to match Player 1's new character.
- Players keep their equipped dice cosmetic, homemark cosmetic, and pet cosmetic. Characters will have no cosmetics equipped.
- Taunts are disabled in this mutator.
