Mulligans
Inspired by Grimgia’s deck. I changed it to fit within highlander paladin.
The combo:
Have Immortal Prelate, Sylvanas, and Recurring Villain all die EXACTLY ONCE.
Then play Da Undatakah. He will permanently gain the deathrattles “shuffle this minion into your deck, resummon this minion, take control of a random enemy minion.
When he dies, draw him and play him. He will keep his old deathrattles on top of the new ones gained by playing him.
