Decided to get myself those cardbacks for heroic PvE.
Seems like all the good decks against Coren has to include Kel'Thuzad.
Worry not. I tried to get something without him - and I won my first try.
Never got to use shield slam or any legendary listed. Just replace it with heavy minions or annoying taunts like alley armorsmith as it gave me 6 armor and saved me from a lot of face dmg.
My win condition was 7 mana 9/5 at first turn. + Arcanite Reaper + Upgrade + Taunts.
BRAWL IS THE KEY CARD. BRAWLED TWICE WITHIN FIRST 8 TURNS TO CLEAR THE BOARD TO A SINGLE GRIM PATRON TWICE.
Face is the place, dont you ever trade.
