Fun things you'll see while playing this deck long enough:
1. Several nearly immortal and infinite Dr. Morrigan.
2. Dr. Morrigan summoning Kel'Thuzad after your opponent board clears.
3. 7+ Thaddius.
4. Kel'Thuzad summoned by Fel Lord Betrug resurrecting any other minions summoned by Betrug. (If you suicide them that turn.)
5. 2+ Kel'Thuzads on board at the same time
6. Playing Arch-Villain Rafaam and relying on the quest hero power for a win.
