Shadowverse

The main thing is, when I saw the packs, I immediately thought: it would be hilarious if an animated Dashka dropped.

And I also got a second Neph and a Matriarch.

You're showing off... I only got the second Albert, without animation.

The game has been downloaded 7 million times, or something.
I also got Albert, the third one. Although, I crafted the second one.

I didn't get anything...

And Revan previously wrote that it had already been sold to a billion people or something.

I wrote that Shadowverse's annual revenue (2016), compared to Hearthstone's 395 million, was one hundred million, and that it was only launched in the summer on phones, and only appeared on computers at the beginning of November. I couldn't write anything about the number of players.

By the way, my last attempts to play Seraph ended either in premature death from aggro decks or Odin (if it's control, then almost certainly he's in your opponent's deck, and it's not a given that there's only one).
