Go to your card list (in the menu), tap the card, there's an option to do just that.

Be advised, during Tournament of Dragons Heroes Carnival any card in a deck, that has been entered into any of the three tournaments, also becomes marked as untradable, until removed from that deck, or the end of the tournament.
