I think more than being a strong deck, Druid (both Jade and Token) were easy to play. Your plan was fairly straighfoward and Innervate was both your free-win and out-of-the-jail card.

All in all, I think Machinegun Priest is stronger but it's harder to play and I believe you can perhaps tech to counter it. Druid was super easy and if one deck was giving you trouble you could easily put tech cards  to counter what is giving your trouble.

With the nerfs I doubt people will keep playing it that much. The slowness of the deck is visible now and you can't yolo Ultimate Infestation turn 5 to catch up.

Honestly, even if Druid was not top dog, I'm happy with a little meta shake up.
