Uhh not really...
I was lucky with that Groudon, it was caught after 20+ Luxury Balls.
And I also caught shiny Rayquaza using the same PIDs, again using Luxury Balls.
But Zapdos is giving me a slightly hard time, I tried twice before it's caught in a Luxury Ball also, although the Zapdos isn't shiny, but it's Modest, with HP Grass 70, IVs of 31/23/31/30/31/31 IIRC.
