While we wait for past BURs to be approved, these tags got lost in the debating shuffle. These were originally featured in the infamous forum #338346, but all but these got attention.
Striker Peach was approved in forum #276555, and Striker Daisy in forum #297493, while Striker Rosalina had her name corrected alongside these two in forum #305687. All Striker tags for reoccuring characters have a shared issue, and that's the fact that, unlike the other costume tags, none of these share the same design from game to game. If you want to find a specific design, you'd have to search the tag with the copytag, which is functionally the same as searching the copytag with the parent tag, so honestly we should nuking them for consistency's sake.
However, if we're going to lump similarly-designed costumes in forum #405336, that weakens the argument against the Striker tags significantly. So, what I'm going to do instead is just copy Kalp's proposal for these wholesale, and allow y'all to debate on it.
