Went back to the Target I got the tins before, got another Yveltal tin, I filmed myself opening the tin and the packs and it happened again, of course I needed proof, my cards in
XY pack 1: Lunatone, Inkay(74), Fletchinder, Herdier, Super Potion, Bibarel Rev, Swellow, Inkay(74), Fletchinder and Herdier
So I got a rare reverse meaning you could supposedly get a common reverse in these packs, I just happened to get two uncommon revs in the previous tin, it seems this proves rares and revs are put in separately.
It also seems less likely to get a holo rare in these packs as I got 4 non-holo rares in 2 tins from XY. But I'm not positive.
I also got doubles in this pack which didn't happen in the first two packs. This pretty much confirms my idea that some cards are in "one part of the factory" and other cards are in another meaning you may get certain packs with the same commons in them and once in a while find a pack with different commons that aren't so common. I had Inkay 74, Fletchinder and Herdier in the same order twice in the same pack so these three must be paired up often.
Pack 2: Doublade, Team Flare Grunt, Gurdurr, Great Ball, Ledian, Yveltal Rev(Needed this one), Rhydon, Ledian, Diggersby and Corsola
So these tins are great for players, not so great for collectors like me so I won't be buying anymore at least not from this Target. Not that I need more commons, just the rare ratio doesn't seem great to me.
I haven't opened the rest, the other two packs, 4 XY boosters and another tin from 2013, so will post later on those.
Edit: Opened the others and only thing to note is a Blastoise ex, looking for full arts of Blastoise and Venusaur and think I'm close to finding them.
