Actual comments on the Disciple of C'Thun page:

"I use him even in my non-Cthun decks. Look at the value. He's basically strictly better than Stormpike Commando"

"Nice card, not only in C`thum decks"

"Lol, I'm kinda tempted to run this in a deck without C'Thun"

"This thing's great without the C'thun ability"

"This would be playable without the C'Thun effect. It's almost always better than Argent Horserider because the battlecry gets past taunt."

What a bad card.  Only useful if you play it on Turn 3, bad.

I can expect some use in Odd face hunter, but im not sure if this card will fill in any deck since it's a worse version of Fire Plume Phoenix because isn't a 2/2 (should be a 2/2 to be balanced imo) 

Arena card for sure, it's still decent and it serve as an little answer like Fire Plume actually is.

Disciple of C'Thun, but you're swapping out the reason you put this in your deck for a mech tag.

*please do not find place in crazy oppressive aggro deck*

In arena can be useful

C'thun, C'thun!!!

Give your Mecha'thun +0/+0 (wherever it is)
