An early Togwaggle's in your hand can add a lot of Beckoner's or Disciple's to your deck. Those are the 2 main C'Thun buffers, as they are very cheap, and Beckoner has solid stats, for 2 mana and Disciple has a great battlecry.
This is my personal C'Thun deck I’ve made. It had many ways to get your C’Thun quite strong very early, while still drawing to get your C’Thun. My average C’Thun is a 20/20 by turn 6. Sonya Shadowdancer and Spirit of the Shark make it very easy to get many buffs to C’Thun. Disciple of C'Thun is amazing with both as you can repetitively spam his battle cry to clear your enemies board. Blade of C'Thun can wipe out those massive minions your opponents have while ramping your C’Thun up for that massive next turn damage. (If you really hate your enemies play Spirit of the Shark on turn 9 and C'Thun on turn 10)

I’ve thought about it, however having second copies in the deck is crucial to getting the massive C’Thun. The higher probability to draw these cards is essential.
