The deck is getting countered hard!
Which is good! However, I've changed things up to counter the counters. The deck in its original state still pulls great, but I've since removed 1 Primordial Drake and The Lich King in favor of 2 Bonemare cards. They're performing EXTREMELY well in this deck. Find a Jade to cast the +4+4 & Taunt on and trade efficiently, or rush face vs. decks that can't heal but threaten you losing control.
Number 1 enemy right now are Control Paladins with Skulking Geist. They can hold you back long if you can't build your Jades on curve and eventually take over with their clears.
Here's the stats for the deck so far.
This deck is nuts right now, Ultimate Infestation, Spreading Plague and Druid of the Swarm allow you to handle ramping and building Jades, you need no other tools. I'm currently 14-0 from Rank 9 to 5 5 stars, intending to hit Legend with this soon.
Keep: Wild Growth, Jade Blossom, Druid of the Swarm. Keep Innervate if you have Nourish AND Ramp, otherwise toss it. Keep Spreading Plague vs. Shaman (and if you know Aggro Druid/Warrior). It's a bad keep vs. control most of the time so I don't keep it vs anything but Shaman.
Enjoy this broken deck, it's really strong right now mainly due to Spreading Plague, that card singlehandedly wrecks aggro.
The Lich King can be replaced for Cenarius, Malfurion the Pestilent or Kun the Forgotten King (in order of importance), he's only there to paint a target on his back and stall, his tokens aren't great except for Obliterate. Still recommend him though, people go apenuts to kill him.
Don't be afraid to take damage setting it up, just make sure you try not to mill your own deck. Leaving a 6/1 up after Ultimate Infestation is fine, for example.
