Hearthpwn

A card that can be useful with any minion that has a good effect while simultaneously making both copies easier for your opponent to deal with as a trade-off. The negative stats are designed in such a way as to keep it usable without making it too abuse-able. If the target dies from the negative modifiers, the copy isn't made.

Gives Y'shaarj double the value, but also useful for a Rag, Ysera, Valen, or Sylvy, among others.

As the storehouse of thousands of generations of magical knowledge, Dalaran's archives hold the mysteries of how to cast any magic, no matter the source. All you need to know is where to look... don't you know the Dalaran Decimal System?

A card that has potential to create killer freeze mage combos, fuel for Archmage or Flamewaker, or even just an extra add to a chaotic Yogg deck. Be careful not to fill your hand too full and mill yourself!

I accidentally submitted a design already (my first time, I made a mistake... oh well), but I did have another idea, this one for a mage weapon. Curious if it is, or could be, balanced and useful. Also, lore-wise, I just looked up WoW-famous mage stuff and the Scrolls of Meitre stood out. Not sure if it fits or not, but...

Was thinking one offensive, one defensive, and one utility added effect to keep it flexible and game altering (as a legendary should be) without being too overpowered. 

Trying to capture the flavor of the WoW weapon with its chance-on-hit to lower stats. Like a nega-version of Sword of Justice, only handing out negative stats seems more powerful than positive ones so it has less durability. Also, it seemed to fit rogue flavor the best.
