I think that recent uptick could be due to the Halvening promotion, and people getting in on the new Summoner airdrop, and of course PowerDowns from Steem - an obvious place to put that is Untamed Packs.
I bought some pretty inflated DEC yesterday to get 50 Untamed packs - I was intending to get 100, but didn't like the price so I settle on 50.
Thankfully I got a gold legendary so that should pay for the entire purchase.
We'll probably see an increase in active players because you have to play 5 a day to qualify for the daily Half drops - I just lost a quick 3 on the trot to get my five in!
Congrats!
I only got one of these once :)
But I dont buy much of a packs, mainly get my cards from the market. No problem for the 5 games daily for me.
The packs are a gamble for sure, quite a lot of fun opening them too!
