Shadowlands. It felt like a lucky buy though because the next priced one was about 7mil and then just went up from there. I got the Akk dog for 8.5mil.
It has a lot to do with timing, but you have to be careful with waiting too long for prices to drop on these packs because it seems like people are buying less of them so the prices jump back up faster. Or, to me it does. Maybe I'm just imagining things lol.
