First off, let me praise one of the best removal cards in the game: Earth Shock. Why? Here's a list of troublesome things you can easily kill with no repercussions:
- Argent Squire
- Bloodmage Thalnos
- Leper Gnome
- Loot Hoarder
- Scarlet Crusader
- Twilight Drake
If you have one spell damage, add to that the following:
- Argent Commander
- Edwin VanCleef
- Questing Adventurer
Not to mention all the other things that could use a good silencing! This is by far an amazing card that can really help to thwart your opponent's plans.
Acidic Swamp Ooze is pretty important in this meta - Eaglehorn Bow, Truesilver Champion, Fiery War Axe, and even Jaraxxus' weapon are very commonly seen. Hold ooze against weapon classes unless you're certain they're not running them.
The midgame is where things really get going with this deck. Yetis, Argus, Sen'jins and Harvest Golems allow you to make good trades and wreck when combined with Flametongue Totems. That said, you're most likely going to be playing board control until you can pull off a finisher with Ragnaros or Bloodlust.
If you don't have the legendaries, you can replace them with Argent Commanders, Earth Elementals, or any other reasonably big and scary minions.
