Activate the Deathrattle (Deathrattle + Quest)

Deathrattle decks are one of my favorites and this expansion has added quite a bit of new synergistic cards for it.

The idea is just to play the deathrattles and use cards to trigger them like Wretched Reclaimer or copy them with Vivid Nightmare.

I really don't know if Activate the Obelisk or High Priest Amet is good enough in this deck and if you decide to purge them, it makes the deck quite cheap to make. I won't know if either is good until the deck is played.

Any suggestions would be much appreciated.

If the deck gets some support I can do a more in-depth guide if wanted.
