With casual back I thought I'd post my warp stranger deck. The idea is to play out two stoneshakers then warp out all your strangers for free and kill with either grim stranger or soaring stranger.
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 haven't tried the forge, but here are my concerns with using it. The deck often has a difficult time getting to five power and when I do I usually want to use the power to cast out the more important strangers. The stoneshaker's reduction is permanent while the forge's ability only works while the forge is in play. Lastly, the forge does nothing unless a clever stranger is play where the stoneshaker eats removal or acts as a chump blocker buying me one more round.
