 Legendary cards: 

L1: Fire Warrior

L2: Spirfire

How can I get 5 stars for these cards that are only in the gift chest? It turns out that it is necessary to have 83 copies for each card. It is clear that you will have to open gift chests. Is there some algorithm for how best to open? It seems to be more profitable to open level 5 chests. Has someone already calculated how many chests need to be opened to get 5 stars for these cards?
