Doomsayer is crucial vs aggro decks. If you're facing control, just try to get as much card draw as possible.
Here’s a little bit of Shudderwock Shaman theorycraft. If you play Lifedrinker x2, Murmuring Elemental, Grumble and Saronite Chain Gang, you will deal 12 dmg and heal for 12 every time you play Shudderwock. You will be guaranteed to get him back. Even though the order of battlecries is random, meaning you may trigger Grumble before Saronite Chain Gang, because you played murmuring elemental, the second time Shudderwock’s battlecry triggers is guaranteed that Grumble will give you at least 2 copies (up to 4) of 1 mana Shudderwock to your hand. The rest of the deck is stall and clear. You have x2 Doomsayers, x2 Healing Rain, x2 Lightning Storm, etc. There’s 1 stonehill defender, but it may be good to cut something to add it instead. Since your combo consists ONLY of minions, it makes Bogshaper really good. You can combo it with x3 unstable revolution on another minion or even more if it sticks on turn 7. Good luck and have fun!
On the second thought, you may want to not include Hagatha as she can mess up the combo. If you trigger battlecries in this order: grumble, saronite chain gang, Hagatha, (…) (murmuring repeat): Hagatha (…) it will just just clear your board.
