Thanks for the feedback. I readily admit that I played only 15 or 20 matches.
(1) Yeah my first inclination was to swap one or two loams for one or two more lands maindeck.
(2) Fair enough. Maybe a better way to put it is that I just never felt like I had enough creatures on board, in particular given that this deck wants to dread return moreso than a stock dredge list (hence the 3 maindeck vs. usual 2). You get stuck with a Narco in hand, not a ton of lands to trigger Bloodghast, etc. Just always felt like a struggle to get to 3 creatures on board. Then when you did dread return, you were all in, since it basically wiped your board (except maybe an amalgam coming back).
(3) Point take on not having to rely on bridge. But given that this deck is slower than stock dredge (though maybe you disagree there), I really want some grave hate to slow the opponent down.
(4) On this I guess I would need to fundamentally shift how I think about dredge. Always felt like I needed to maximize game 1 since games 2 and 3 can be so tough. What did you cut for more grudges?
