I could definitely do one of those Sovs, if you prefer that. (I'm not sure if you meant the one with Penguin or the one with Cells, but, either way?) As for the Latias 'gon, I'm not... sure either? xD; I mean, I'm not sure which pets of mine you might have a preference toward over others? I could always do the Deserthorn + KS or something?
Or I could do Sov + Deserthorn + Shrine Fellox for the two Paragon?
