Ok, the "combo" is these 3 cards: Swans of Bryn Argoll, Seismic Assault and Dakmor Salvage. So, I discard the salvage to hit the swans for 2. I draw 2. Instead, I decide to Dredge 2. So do I ever actually ever get to draw any cards off of this if I continue the process? Or does dredge just replace everything. I was told this works, but I dont see it.
