Ugh… Got wrong mercenary opening packs - #3 by SparkyElf-2852
You can do that if you want to. I’ll tell you whether there’s a problem with duplicate protection in your particular case, although you could figure it out yourself after reading what I’ve suggested.
PS
I was about to say that we’ll take your word for it here (it didn’t make it into the final edition of the post), but actually, if you claimed the free Tyrael mercenary from the shop, you can find it in the purchase history in your profile [1] .

PPS Have you got one of Tyrael’s portraits from the achievement by completing the heroic Secret Cow bounty? It can be frustrating to get a portrait from packs that could otherwise be claimed from an achievement, especially if it’s an epic or a legendary one, so if you haven’t, I would recommend it.
