A deck from yesteryear, updated to the modern age: it's Hadronox Druid! One of my all-time favorite decks, it never received much in the way of additional love until Murder at Castle Nathria changed that. Now with the return of Deathrattle Druid to Standard, we can borrow some of that goodness for Hadronox and N'Zoth, the Corruptor, along with all the various other cards that have released since then:

• Prince Renathal gives us more Health to work with, keeping us alive just a little bit longer until we can get the Taunt-wall going.
• Hedge Maze allows us to proc Hadronox without relying on the downside of Naturalize.
• Death Blossom Whomper could end up borrowing Hadronox's Deathrattle, allowing us to revive even more.
• A ton of card draw has entered the game, including tutors (Capture Coldtooth Mine, Aquatic Form) and copying tools (Moonlit Guidance).
• And, of course, the elephant in the room: ramp. More specifically, Wildheart Guff is just amazing, and will continue to be so until it is nerfed lol.

I've been tweaking it a lot as I get feedback from elsewhere, but any additional input would be appreciated :)
