Hearthstone cards are numerous and often hard to spell. Reddit HearthSearch provides a way to search for Hearthstone cards without leaving Reddit. While writing a comment on Reddit, type '[[' to open a small menu beneath the comment area. Type part of the card's name in the text-box to search. All matching cards will appear in a drop-down. Select the card from the list and it will be inserted into the comment like '[[Deathwing]]'. This format is compatible with /u/hearthscan-bot which will reply with an image and description of the card.
