Today I learned that Solarian Prime was a Demon when The Amazing Reno killed her with Sacrificial Pact before I could attack with her.

FYI, this does not make dormant minions disappear.

Indeed! Just won a game in part because an enemy Maiev Shadowsong made one of my heavier minions dormant, allowing it to survive Reno's battlecry.

How many gold do I have to spend to unlock it? i can't undertand

2800 gold, since you need 700 to unlock each of the four chapters of Galakrond's Awakening.

Too bad this is not the artwork 

I can't believe Twisting Nether lied to us for so many years

 The 'fatigue' Reno! That what i would call it.

Srsly this card is amazing. That is EXACTLY what mages needed: A way to clear big boards. The armor is nice too and the spells are RNG yeah but hey that is the best board clear in the game, better than Plague of Death(no res pool). Mages always struggled with clearing boards too large for an FS. With this and Khadgar, King Phaoris and Power of creation Mage can now clear and build up big boards nicely. 5 star because its perfect for the class(to me 5 star doesnt mean ultra OP in any deck just that its a perfect addition to some decks).

Seen A Post on Reddit complaining about serious lack of Potential with Reno and The Adventure Ending.

Seriously, How could they deprive Mage of this "Amazing" Hero Portrait. I really need this :(. 

There are so many Reno cards one could wonder Blizzard might have run out of ideas.

The Amazing Memo

I have personally played against The Amazing Reno because a Rogue player was able to cast Academic Espionage while I was playing Mage.  My point is that from my experience Reno's battlecry only removes from the game the creatures in play not in hand and deck.  The Passive Hero Power is mostly really annoying to play against but sometimes works in favor of the opponent. 

What did the Hero Power cast? Were the Spells purely Mage spells? Or does this HeroPower Throw out Any Spell from Any Class?

It's from any class

I think he cleans the entire table until he is the sorcerer's Twisting Nether as a sorcerer, it makes me understand that :)

If I had to make an educated guess, I would say that this basically reads as "Silence all minions and remove them from the board." but with HS flavor.  They don't die so they don't hit the rez pool and no deathrattles trigger.  They chose not to capitalize ALL, so I don't think it targets anything other than what is on the board.  Needless to say that would cripple pretty much every deck.  Ever.

From a technical perspective, the Battlecry moves all non-Dormant minions in the Play zone (battlefield) directly to the Set Aside zone. No silence is needed because minions in the Set Aside zone do not affect play.
