I just played against this deck as Shudderwock and I won with 4x Lifedrinker (Zola, Grumble). It's just too much damage, considering the battlecries of the Control Warrior often don't trigger in the right order. Even if Cornered Sentry comes before Drywhisker Armorer, there's likely a Bloodrazor inbetween who kills the Raptors before you gain armor with Drywhisker.
After the expansion there won't be many Shudderwocks anyway, as people will want to try new decks first, but if Shudderwock will come back after some weeks and if Control Warriors will still be obsessed with the idea to counter Shudderwock with Azalina, then I'd tech in Spirit Echo as the Shaman. How about 6x Lifedrinker? That's 18 damage per mana = 180 damage in one turn. Good luck!
