With 65 packs. Not much. Although, I don't really need new legendaries; the one from the update before last is good enough for solo dailies, but still, the randomness could have been a bit more generous.
And there's also a new solo quest event with fun opponents. Smeshariki in Heroes of Might and Magic, how long I've been waiting for this! (no)
I've already completed almost all the missions; I just have the ones for 30 wins and winning with a deck of gold and legendary cards left. Tenko with Kelams and Themis handles all the Smeshariki well. For the transformation quest, I dug up an old deck with Leva and Mutabolts and added a couple of Medeas. Without evolution, I took Roach 2.0 again; the rest is not that difficult.
I'll finish the remaining missions and can then calmly return to Gwent... It's especially interesting there now; they added an update with card changes, a journey (I haven't really looked closely at what it is, but it seems to be a small story with a lot of rewards for completing tasks), and new leader abilities for all the Factions.
