I guess, but this card really shines in warrior and priest. Summoning two recruits is really good, so I would say yes.

what will happen if you use on a double shadow form hero ?

Not proofed, but i guess you get your basic evolved hero power. Card Text says: "replace your starting hero power with a better one.

I've done this. Your hero power stays either deal 2 damage or deal 3 damage if you did double shadowform. Also, it doesn't let you use your hero power twice like other powers (Heal, Justicar, Heal again - it doesn't let you do it twice like that)

Just got out of a game where I had used Shadowform once.  Playing Justicar didn't change anything.  No upgrade, no refresh, nothing. 

Should I disenchant  a golden Eadric the Pure for this card?

yes. no doubt

I have already disenchanted eadric...  justicar is a really good card.

What happens if you use Justicar Trueheart on Lord Jaraxxus?

MISTAKE

bruh, they affect different stuff bro, nothing happens

I suppose he meant Brann, so battlecry will trigger twice.

The answer is: nothing happens the second time.

Thats the point. It's intended. Facepalm

Upgrade to DIE, INSECT! would be DIE, INSECTS!

well die insect would be like the heroic form deal 8 damage to 2 enemies and Lord jaraxxus's would be summon Mal'ganis.  

Well, technically, that doesn't comply with the rules of English. Unless placed before a "e,i, or y," "C" is pronounced like a "C," not "S," therefore, Justi-kar, while not necessarily correct, is an understandable mistake.
But seriously, is it correct? From where does this information flow?

Thanks.

"Justicar" is a high judicial officer in medieval Europe and the word has always been pronounced with an "S." It obviously comes from "justice", hence the pronounciation.

You're thinking of Justiciar. Justicar is pronounced correctly. I can think of 2 other references to this word in video games, and BOTH make hard C sound not the S sound. (Mass Effect 2: the asari Justicar, and SWTOR: the Justicars on Coruscant.) The word is being said correctly. Just because it is derived from the word justice, does not mean it retains all of its properties.

Why do you care?
