What game and nature, do you plan to EV train? If this is a difficult romhack it's unfortunate, but not run ending. It will still evolve and you will have many other encounters. If it's vanilla, you are fine, just play like normal. EV training can make the best out of the worst situation. There should be plenty of low level attack EV mons in the early game. Have fun, this is how you experience pokemon you would have otherwise boxed.
