Namaari - Morning Mists is Steel's second legendary revealed, after Beast - Tragic Hero was revealed yesterday. She is a bit of a strange one. Her Blades ability is very strong but it is counteracted by her Bodyguard ability. Ideally you would want to keep her protected from incoming challenges so you can make the most of Blades. But you won't be able to do that. Also, her stats are quite weak. She won't be able to take out any big threats on her own. She needs some additional Strength buffs from Support cards or something like Charge! to really be effective as removal. Overall, I think she is kind of mid despite her Blades ability.
Sardine Can is the first card we have seen from The Rescuers and, boy, is it an intriguing one. Ward is a powerful ability and being able to give it to your whole board is strong. It's Aurora - Dreaming Guardian, except impossible to remove unless your opponent specifically runs item removal. Now imagine running this in an Evasive heavy deck... your characters will have Evasive and Ward, so are protected from most challenges and can't be targeted! I can see this card being the center of a deck that just looks to build an un-interactable board, forcing your opponent to have item removal or they just lose.
Donald Duck is Ruby's first legendary card reveal in Rise of the Floodborn. And he is another one in a series of legendaries which have 1 natural lore but can gain up to 4 additional lore, if the right conditions are met. He seems like a natural fit for the Ruby deck that synergizes around damage to your own characters. That deck probably wants to be paired with something like Steel, for more ping options, or maybe Amber to heal and gain additional value. I don't know how good that deck will be, but it will be an interesting one to try and build.
