I can't believe the birds are available, again! GameFreak is doing way too much to cater to the "Gen I is the best" complainers. At this point haven't the three of them been available like 3 times, Gen III, Gen IV, and now if I'm correct? If you honestly haven't captured them by now why would you even bother beyond filling the Pokemon, which any legendary (like a new undiscovered one) would do.
Is Moltres, Articuno, and Zapdos even that popular to begin with?
Don't get me wrong, I like them all, but I don't see the need for them in particular to be so abundantly available.
