Question with Annihilation, one or all cards?

Hello, sorry is my English is bad.



My question is with the card Annihilation. http://ift.tt/1wHBirz



If I use Annihilation in, for example, the card Dwarf, I "put it back in the box and forget it", only that card of Dwarf? Or, The card of Dwarf? (all the card of Dwarf in the game)



Thanks.
