Legendary Riptide Specialization (You may only have 1 Spike Pit Trap in your deck and only if your hero is Riptide.)
When this defends and the attacking hero has played or activated a reaction this chain link, put the top card of their deck into their graveyard, then they lose X [Life], where X is the number of cards in their graveyard with that name.
