personally, I think that way further on, Blackbeard will challenge shanks after mastering both of his abilities (and possible other ones) and will win. Luffy (who by then will hopefully be a lot stronger) would then get uber angry and challenge blackbeard, and win. I plan for this to happen near the end of the manga/show. Thats what I think.
