OTK Control Shaman (Season 28)

It's important to take control the board as much as possible versus aggros or zoos. You do not have to keep rockbiters for combo. You'll have pressure on your opponent with other minions you have.

That matchup is kind of stressful because you need to draw luckily. You have to draw your combo pieces as quick as you can. There are N'zoth decks on meta. So you should save your hex (at least 1) for chillmaw. Taunts are annoying. Furthermore You should save your both of your rockbiters if your oppoent is Warrior you'll need them.
