My take on Dredge.
There are a lot of lines of play to be aware of to make sure you get value every turn. Don't be afraid to swing out every turn to get damage through even if they have better units.
After dozens and DOZENS of games, I feel like some past iterations failed consistently, while somehow this balance has been doing very well. I don't understand the algorithm in play, even if I only swap out the exact same cost cards for different ones, sometimes that seems to make the deck just absolutely fail. But after much testing, this has been what I am going to call, consistently consistent.
Condemn Extra access to the market, plus potential voidbound or the last hit needed.
Darkwater Vines - Mill yourself, mill your opponent, see what they are up to.
Gravitur Trainee - Discard EN, DW, and CS, or extra power.
Endless Nightmare - Discard ASAP or run out ASAP if your hand is bad, attack with this unit constantly.
Malaise - Mill yourself on your turn only.
Sporefolk - Self mill, chump blocker, discard target if your void is already looking spicy.
Dawnwalker - Discard asap, or swing constantly, chump block with. It will be coming back.
Ebon Dune Smuggler - End of opponents turn market access plays well with Endless Nightmare, or chump blocker.
Katra, The First Seal - RAMP, I guess it does other things? Mostly makes sure we can cast Clocktower Sentinel Worst Case Scenario.
Fear - Finisher/discard, I feel like this is a flex slot, so play him however seems fit.
Valles Rex - Surprise blocker for days, do whatever it takes to make this guy cheap. Play end of opponents turn for surprise concession.
Clocktower Sentinel - Discard this ASAP or cast it later thanks to Katra.
Shoaldredger - Easy discard, easy big boy.
Crest of Mystery - Put Clocktower Sentinel on the bottom of your deck FFS.
-------------MARKET---------------
Dismantle - Against Adjucators Gavel mostly, we don't care about Dichro's Ruin, but it feels annoying.
Forget - Do with this what you will.
Shield of the Line - Surprise win condition, grab if you have 4 power and opponent is tapped out, and you have CS in your void.
Fall to Ruin - SOMETIMES you need to clear the board. Yours will probably come back though.
Xenan Banner - Playing Katra???? IN EST ECONOMIA?!?!?!?! This is usually necessary to get your influence straight. You can cut it if you have better luck than me, but when I cut it, I immediately needed it in the next 4 games.
You might also want to try Gravitur Trainee.
