The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
Copied from a comment on earlier version of this list: "The extra cards are situational Relics and Power cards. Since you can draw the Relics at will with Display of Knowledge, there is very little downside to including them. An unplayable Relic can be stored in the Market for later use. It can also be Scouted to the bottom of the deck, and then you can get it back later when the situation calls for it. Display of Knowledge has other uses of course, but in this deck it functions mostly as a 3-cost Celestial Omen for specific answers." Not everyone agrees with this evaluation, but you can see a fuller discussion here: https://eternalwarcry.com/decks/details/TOBg9Lqxm94/auralian-imports-exports
