Well, I'd hold on the evolutionary stones. In addition to what I already have in my bag, I could need up to:
Fire Stone x1
Water Stone x4
Leaf Stone x4
Moon Stone x1
Sun Stone x2
Shiny Stone x1
Dusk Stone x1
Dawn Stone x1
I was on GTS Negotiations, and for a minute I thought I was about to get a Latias. And since I just collect them for the Pokedex, I would have given it to you for nominal fee.
