Team B. Felix has the chance of being the best young pitcher to come to the majors in 20 years.
Danks is good, right up there with Volquez and Diamond in the Rangers system, and could be dominant as well. Cain is good, too. Unless you believe in the TINSTAAPP theory, then I would go with Felix. If you think that a quantity of pitching prospects is better than a quality, you might do the trade. Honestly though, I believe in this, but would still not trade King Felix.
