In-Battle Reroll
If your 3-ball selection is unfavorable, the reroll option lets you change your assignment in battle. Reroll is a match decision, not a permanent shop unlock — its cost or limit must be read in-game each session.
When to Keep
Keep your 3-ball selection when at least one S-tier or A-tier ball appears. Saving the reroll for a worse hand is generally more efficient than burning it on a marginal upgrade.
When to Swap
Use the reroll when all three options are C-tier or below, or when you have a single strong ball paired with two unplayable options in 2v2 mode.
