The Three Cards Spread
The three cards represent the past, present and future in terms of time — or context, focus and probable outcome in terms of problem-solving. The middle card can also be read as the current influence, and the rightmost card can be read as representing the querent's hopes and fears.
This layout is well-suited for expansion by drawing additional cards from the deck. For example, a card can be added in response to a follow-up question regarding a card previously drawn; lay the additional card a bit lower and overlapping the overlapping the previous card. You may want to try the “Choose from spread deck” option and manually choose additional cards from the rows of face-down cards.
