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.
I didn't really understand why Skycrag until I played this. Whispering Wind and the Throne Room package make for a very interesting high synergy deck; I really love it.
Use Whispering Wind or Know When to Hold 'em to draw it. After that Plunder it, discard it, or put it on the market. You can Plunder 3 with Maveloft Huntress to get SSS, but this is bad because you should never have more than 5 or 6 power with this deck because is not good take much damage from Krull, Xumuc Occultist.
