I think I know the answer to this question, but I'll ask anyways: are two Pokemon of identical CP/stats caught in the same location by two different people guaranteed to evolve the same?
I've been working overtime to get a Gyrados without Twisterliving near water, Magikarp are plentiful, but I've had three straight Gyrados with Twister, and it's getting to the point of ridiculous.
I have a 100% IV, 182 Magikarp to evolve, but a friend who was with me and caught the same Pokemon evolved hers and got Twister. I'm hoping I end up with something else decent to evolve by the time I get to 400 again (I'm at about 240 now), but I'd love to have some hope that this beauty could still come through for me given its other benefits.
