Against aggro keep clear boards on hand. Against control or combo deck keep all draw cards. Shudderwock is always welcome in starting hand.
Well known infinity Shudderwock combo. I added more draw to deal with Quest mage and Mech C’Thun. Elementals grants you 100% chance to return Shudderwock back in hand, just play him in combo with Murmuring elemental (you need to reduce its cost to 1 mana). Once you start Shudderwock combo, there is no back for your opponent.
