Whenever Captain Lannery Storm attacks, create a Treasure token
That said, theres one thing that does put a dampener on the whole experience: the price
Rapunzel - Gifted with Healing (The First Chapter) Unlike Robin Hood, Rapunzel is not that much of a surprise for a card from the oldest set in Disney Lorcanas current lifespan
Of course this isnt really a new mechanic at all, just a reimplementation of the saga mechanic introduced with Dominaria (and later reintroduced with Theros: Beyond Death and Kaldheim)
Why it makes the blood token is probably the discard it can provide, but Im sure it will be a fine addition to Strefan, Maurer Progenitor and Anje, Maid of Dishonor decks everywhere as well
Its good early and late, and helps you with situational cards, like discard spells against an empty-handed foe, or removal against control decks
