I am currently looking towards building a very physical character, in Vampire the Requiem. I am wondering if there is any clan/ bloodline, that gains all physical disciplines (Celerity, Resilience, and Vigor) at a in clan cost?
No such clan or bloodline exists.
It's easy to see why, from a game design point of view. Such a clan would be superior in all physical activity - especially combat - while not possessing any original discipline or distinctive feel, since all it's abilities would be common across many clans. (What would the defining 'feel' of such a clan be? What kind of people would they Embrace, other than "physically fit"?)
Characters from this clan would have little to contribute in non-physical situations. In a game about social interaction like Vampire, that would be the kiss of death to game design. (Compare to, say, Gangrel - an example of a clan with a strongly physical nature, but a completely distinctive feel dripping with a personality that encourages several types of character design.)
It's perfectly OK to design a physical-only character, of course, but game designers wouldn't want to include a clan that doesn't allow any other kind of character.
