Will it disappear? I'm scared of removing my cards, need to know what happens.

The card will just be in my collection but not in your deck anymore it won't dissapear so don't worry you can always put it back in your deck later again by going to my collection

Oh thanks a lot

oh, but I do wonder why I lost my halo smiley. I guess it's because I use dial-up, maybe my opponent moved but I never received it.
