If you come across a term that you think would be useful to add to this list, or if you're an experienced hand and would like to suggest a better wording for a definition, please let me know your suggestions via the site's messenger function.

Tutor - A card that allows you to search your deck or discard pile for a specified type of card and move it to another location, usually your hand. (From the MTG card, Demonic Tutor.)
