This is a 4 mana sticky minion with 12 stats. That's more than a piloted shredder on average. I'm not saying it's good, but it can't be that bad. Two magma ragers in a 4 drop is some serious value. 

This is probably better than "Earth shock all enemy minions", for only 2 mana, no less. 

Every expansion there are people who say that the expansion is crap and that the cards aren't worth playing. Every time they are wrong. Sure, the vast majority probably won't be super competitive, but even in BRM for example, when there were only roughly 30 cards, and there weren't any good dragon decks, the few cards among the pack that were really strong had a considerable impact on the game and the meta. 

None, because I want to collect cards. When I quit or leave the game for several years, I can always come back and remember all of the cool cards I collected. Plus they are useful/fun for brawls and wild.

It's not that exciting imo. Basically the Skeram Cultist with weaker stats for an extra +1/+1 on C'thun which I don't think you need. Honestly I think C'thun decks are unlikely to use lategame C'thun buffers. Once you play Beckoner, Twilight Elder and C'thun's Chosen twice your C'thun is already a 16/16. 

Also really boring flavour wise as it's so similar to Skeram. 

 I think you missed the part where it has Taunt. 5/7 taunt for 6 is pretty decent, the battlecry makes it even better.

 Well it's still just vanilla stats. You don't play vanilla 6 mana minions, you lose too much tempo. So the question is whether the battlecry is worth it. And I just don't think so. The early game C'thun minions can already buff him up to huge stats, at a time when you can afford to play more vanilla minions. You can't really afford to play vanilla minions in the lategame.

You should focus on playing one class but don't disenchant the cards from other classes. The really bad cards you may disenchant if you need the dust right away.

Nobody asked for a nerf on River Crocolisk  yet...     So here we go, I want that card to be nerfed....

If you have either Tuskarr totemic or totem golem, you can play this guy on turn 4 if you use your hero power for a turn. Obviously that does come with some tempo loss, but it isn't so bad with this being a 4 mana 5/5 taunt. If you happen to have two totem golems, two tuskarr, or one totem golem + 1 tuskarr, you can play this card on turn 4 with the help of the coin, which is very, very good. If none of these work, you can play this for free basically in the late game, which could ultimately be what this card is best for.

Also interesting to note that Master of Evolution will transform this guy into a 7 drop. 

I read this, thought it said at the end of your turn, and got really excited that C'thun decks and so forth could be much more consistent, but now after reading it correctly. eh.. Probably won't be played. It has weak stats and will probably die unless you are both ahead and your opponent doesn't have adequate removal. In which case, you've probably won the game already and don't need a powerful 10 mana legendary to close out the game.

...doesn't feel like it should be an epic.  anyway, 6 cost with 8 health, likely it will survive and on your opponents turn it will be a 4/8, assuming they didn't kill it.  6 cost 4/8 is meh stat wise but if you manage to last 1 more turn, you get an 8/8 minion...but how likely will this even last to a point where it gets to 8/8?

 Rarity has nothing to do with stats or raw power. This card is exactly what an epic card is supposed to be -- not super powerful on the surface, but capable of changing the game if played in the right situation or in combination with the right cards.

Turn 8: This + Conceal + Cold Blood = GG

Ball of spiders + this = 6 beasts, all webspinners. Those 6 webspinners give beasts -> Also all webspinners.

Mind blown.
