The excitement is clearly palpable. But so far I see very little to indicate they've learned anything. Tar Watcher is a maybe, Elise is a super-RNG control/tempo card (because those are SO FUN) which does nothing vs. aggro, Rogue Legendary is almost certainly insta-dust tier, the Hunter legendary is probably only good when it craps out of RNG effects, etc. etc.
I guess their "answer" to the aggro meta is the heavy-handed crab (which is still not auto-include) and the Tar Watcher, which is itself probably fantastic in Zoo. But Zoo is a little more game-friendly than Pirates so eh.
It's also pretty dumb that they continue these week-long card reveal drips, especially after the build up from the initial reveal.
