Jeez, I miss this card in my control mage :/

It's much better than Medivh, the Guardian since it can be used longer and it's cheaper.

Summoning Stone saved my LIFE! :D I was out of cards and my enemy had a hand full of Legendaries (he played the Golden Monkey earlier) so I had already accepted my fate... and then the Summoning Stone (witch I had stolen earlier) showed its true power! :D

Wow that Doomguard :D

The stone can be quite useful!

LOVING this card in my Mage Yogg deck. It just seems to always provide enough of a board presence to keep me alive until Yogg comes and flips his gigantic flaming coin onto the table. 

Love it !

I made a sort of improvised Miracle Rogue with this in it, and I can say that if it isn't killed immediately, it's well worth the 5 mana to play. (Assuming you're using a spell-heavy deck, of course.)

My best experience so far was playing Sprint and getting Archmage Antonidas. XD

Great for control, you can fill a board AND kill your opponents minions with it (Flamestrike says hello). Need the right deck though. I 

I was so confused just now. But I would strongly advice you not to try and counter this minion with Loatheb.....mage played arcane intellect and the stone summoned KTZ....took me a whole turn to figure out how arcane intellect summoned it but had to facepalm myself after I figured out where the 5 increased mana cost came from xd.

Brann Bronzebeard is always the answer

if you use thaurissan to lower the cost of lets say a mirror image from 1 to 0 then summoning stone would summon a 0 cost minion, not a 1 cost one

Very OP card in tol barad tavern brawl. Huge value!

Tol Barad right here

Exactly my point. Based on the downvotes, I'm guessing no one thinks of it that way, even for a joke.

He will also be able to kill you if he's a freezemage, so you might not want to do that. Imagion archmage into any spell into endless 0 cost fireballs. GG

 For your opponent, yes.
