>>58775534I don't hate X, I just recognized very early on that Y was going to be preferable.
We had setup sweepers in the 2014 meta, it felt like Zard X didn't do enough damage even with tough claws and to this day doesn't have a great dragon stab without some drawback. The opportunity cost for using mega Y precluded using others.
Zard Y on the other hand had a sun boosted-stab spread move plus 1 turn solar beam(which doesn't see much play anymore).
