I've mained Jade Druid since it came out, and this version really works well. The Arcane Giants are amazing as you can get them for a really low price, and then use Earthen Scales. It has a good amount of taunts which is great for this meta.
You want to mulligan for Innervate, Wild Growth, and Jade Blossom for all matchups. For aggro you'll want to keep jade idol. For control, you can keep Fandral and with the coin Jade Spirit and Mire Keeper.
The key to this deck is knowing when to play aggresive cards and when to defend. For example, you could play Aya or Jade Behemoth on turn 7. If you feel like you take damage, then play Aya first. because she will help you manage the board more in the long run.
Against control: Try to keep card advantage by making good trades with your Jade Golems. Use Earthen Scales and Jade Idol for Auctioneer.
Against aggro: Try to ramp quickly and get big jade golems and lots of taunts.
Screw it, why am I wasting time with this guide. TBH, this deck is a great list for Jade Druid but right now Jade Druid is fucking shit. Damn it, why did I main druid. I'll finish this when Jade Druid is at least tier 3.
