FYI, I haven't had a single Lucario come out mint yet. They're not as mangled as previous tin cards used to be, certainly, but they all have surface scratches. I'm not getting much less grumpy here!
MT was a huge set. One box, sealed, would probably get you playsets of some commons but definitely not all of them. If you're opening packs from blisters or tins, or packs bought individually at a card store, you're even less likely to end up with playsets.
Update! Pulled a TSD in one tin, and then a Magmortar LvX in the next. Not so bad. Still only one Honchkrow though... and loads of tins more than its reasonable to open left
