Augmented Elek + Plot Twist with 2 mountain giants in hand = 4 mountain giants shuffled into your deck.

If your deck is mostly deathrattle minions, and you play Dollmaster Dorian then Plot Twist with a full hand, you could end up with a board full of 1/1 minions with good deathrattles. It’s an extreme example, but theoretically possible.

Don’t forget the Crystallizer card, that deals 5 damage and gives 5 armor. Nice synergy there.
