Hearthpwn

Worthless in Constructed, OP for the most OP class in Arena. 
This card really should not have been printed. 

Sticky minions in Hearthstone almost always see play, this kind of stat line is better then the opposite, you want to token out first, buff trade get a real minion, could be very very annoying to play against. 
This card is almost definitely getting play.
I think in both Face and Midrange Hunter. 
Sticky minions is more of a Face Hunter staple. 
Midrange hunter was so hard up for two drops it was running Doomsayer, so this card is in that deck no question. 

Y'SHAARJ SHAMAN

I really think Shaman is the proper home for Y'Shaarj

1.) Shaman can cheat out big minions early so they are not just dead plays early 4 mana 7/7, Mountain Giant works well with Ancestral Knowledge, 5 mana 7/8 taunt 

2.) Shaman has amazing early game board clears and removal so you can play deck without dead Y'Shaarj drops

3.) Thing from Belo Protect your win condition with a free 5/5 taunt 

4.) Ancestral Respawn - Helps in a deck that only has big minions if you can get additional value out
