How do I get rid of Mummy Cards?.

Mummy cards are introduced at level 83.
They have bandages on which have to be unravelled before you can remove them from the board.

To unravel you need to match the card with a card from
 the deck. 

The bandage will come undone and a card from the 
deck will be turned over

If you are lucky the new card will match another mummy card, which you can then unravel, and so on.

Try to get as many mummies undone as you can 
before you try get runs. 

Once the bandage is off the card can be removed from the board like any other card.
