WWE is trying to mix things up the best way they can. The brand split is still active, but now they have a Brand To Brand Invitation.
This week on SmackDown, they revealed the rules for this Brand To Brand Invitation. Superstars will be permitted to appear on different brands four times a year. Charlotte Flair appeared on SmackDown tonight and will wrestle Bayley next week. It appears that will take care of half of her appearances on the blue brand.
It wasn’t made clear what a “year” means in this instance. NXT is also not included in the Brand To Brand Invitation. This is kind of like the Wild Card Rule, but they’re trying to limit it so things don’t go overboard.
