You can still play Dungeon Run (and I recommend it 'cause it's really awesome) and get the card back as a reward. I don't know though if they update the card pools from which you can choose for your runs. Around the time they first announced WW they said that they are not sure what happends to Dungeon Run once K&C rotates from Standart. So you have at least a year to clear it with all 9 classes.
Additionally there will be another single player mode that is similar to Dungeon Run (you fight bosses and build a deck as you advance).

After the new expansion hits with his new dungeon mode are they going to be two modes and we'll still be able to take the old reward(card back).
Some answer will be helpful :)
Edit: Or may be nobody knows :D
