Heres how it plays out: You are required to have The Gitrog Monster out, Dakmor Salvage in hand and more than 7 cards in hand total At the end of the turn, discard down to hand size, discarding Dakmor Salvage This gives you a draw card trigger from The Gitrog Monster Priority passes to opponents On resolution of the draw trigger, replace this with the dredge from Dakmor Salvage, milling 2 cards and returning Dakmor Salvage to hand As it is still the cleanup step you still need to discard down to 7 cards in hand, again discarding Dakmor Salvage and repeating the combo above on a loop The idea is you loop this to fill your graveyard and try to win from there
