Staple

A Staple is a card considered so important to make a deck successful, that is is included no matter what Deck the owner chooses to construct.

Such cards can include Snatch Steal, Heavy Storm, Graceful Charity, Nobleman of Crossout, Call of the Haunted, Premature Burial, and Torrential Tribute. Of course, opinions on what exactly constitutes a Staple card are often down to the individual. Many staple cards are, by their nature, Splashable.
