The deck has 62 cards right now, I have to take out two.
The most surprising card in there is Grafted Wargear ...I didnt expect much at first but the card fits very well, it boosts my cats to allow them to deal significant damage, I can sacrifice them for two foods to feed my engine and I can use them to sacrifice creatures when I have no other sacrifice outlet (I equip the creature and I move the equipment)...it is useful when I already gave persist to the creature and I want it to die for it to come back and cause loss of life for my opponents.
The other cards are pretty obvious.
I want a better replacement for Reassembling Skeleton ...2 mana to play it and another 2 to bring it back is too much so I always end up spending my mana on something else.
Deck looks sweet! Has a bit of a funk curve though; 21 lands and a slew of 4-6 drops doesn't seem great even with Rituals and Clamps. Might want to cut some of the fat or add another land or two. I do love the Unwinding Clock though, seems hilarious with the Cat Oven combo in multiplayer.
For Reassembling Skeleton you kinda have to bite the bullet and shell out for Bloodghasts. You can buy playsets on Ebay for 40 shipped or wait for an 8% coupon on TCG to get around that. Gravecrawler is your next best bet but I'd spring the extra couple of bucks on Bloodghasts and get it over with. It's way too good at what it does. Turn 1 Dark Ritual + Ayara, First of Locthwain into turn 2 Bloodghast is bonkers but even just Clamp + Ghast is obscene. 1 mana for 2 cards each circuit, no fuss, no muss. Card is also nuts with Konrad. I know that these cards aren't exactly budget-friendly but once you have Bloodghast your life becomes so much easier because it's basically always going to be an automatic 4-of in these monoblack devotion shells. All of them.
With respect to Stitcher's Supplier I tend to play 4 in every graveyard matters deck. It's too good at what it does, especially when you have things like Clamp and Oven to sac it for the full 6 cards by turn 2. They're still reasonably affordable and it's by far and away the best thing to be casing on turn 1 every game. Milling 6 cards + providing an X/1 body for Clamp + fodder for Ayara/Attrition on and on and on make it a must-have.
I'll +1 the Grafted Wargear and preemptively take credit for it since it's a card that I've been pushing for over a decade. It turns your useless dorks into legitimate beaters because "infinite" 4/3 cats that drain for 1 are no slouch.
While you may need to cut them to make room for better stuff I'll quickly note that Carrier Thrall > Butcher Ghoul unless you have Gravecrawler. The mana helps and you'd rather have have X/1s in your Clamp deck.
Cauldron of Souls makes no sense to me in a deck full of X/1s. What's the idea here? I know that it combos with Butcher Ghoul but that's way too cute. Neither card is especially good on its own so I'd rather see them both cut.
If you have Cauldron + Unwinding Clock, every turn you can sacrifice cats to the oven and they will come back and die once more when sacrificed to add one extra trigger.
If you have Cauldron + several creatures, you can give persist to each of them and wipe your board one by one by doing something like moving your Grafted Wargear around for several triggers.
The persist ability with Syr Konrad, the Grim will trigger both when the creature dies and when the creatures leaves the graveyard.
If you have Cauldron + Butcher Ghoul, you can sacrifice the Ghoul to something, it comes back with a +1/+1 and then give it persist, sacrifice it again to something, resolve the persist instead of the undying ability, it comes back to die again and comes back with a +1/+1 counter. Overall, you had a creature that died 3 times, left the graveyard 2 times and came into play 2 times....the various triggers add up and the creature is still in play so you can repeat something similar on the next turn.
Plus Cauldron allows to protect your partner's creature in multiplayer games.
My concern is that it doesn't help the deck win games that you'd otherwise lose and comes across as being win-more. I've played these kinds of decks for years in a variety of formats and I'm never worried about the games where I have all of my combo pieces alive and well. Sometimes you go turn 1 Gravecrawler, turn 2 Wayward Servant, turn 3 Phyrexian Altar and win the game then and there. We take those. Still, the games that I lose are the ones where my Priest of Forgotten Gods and/or Ayara are killed, I have next-to-no removal and I lose to random beats with my board of anemic recursive threats. Cat is fun and all but it only blocks 1 attacker and gains 1 life each circuit so you're still trivially easy to kill if needed. That's why I don't like to build these decks with a bunch of expensive cards that rely on other expensive cards and other "nondurable" threats. It never seems to work out. Rather, I try to build them in such a way that I still have game even when people are interacting with my key permanents and overall denying me from assembling a critical mass of permanents in play. I'll win either way if they don't so I just have to figure out a way to assemble a decent board and ride it to victory.
I'm just not sure how I would replace them in the other deck.
Do what I do. Sleeve all of your decks in Black Matte Dragonshields and move cards around as needed. That single playset of Ghasts can be used in all of your decks. Just replace them with basic mountains (who would ever put a mountain in their deck amiright?) with "Bloodghast" sharpied on them and move them around to remind yourself which cards are missing. If you switch back to the other deck slot your proxied mountains into this deck to remind yourself to grab your Ghasts before playing it again. I'll stress that you don't have to play with the proxies, they're a reminder for you to get your real Ghasts.
I removed the Myr Retriever ...2 is a bit expensive for a creature in my deck...it must offer a great advantage or it just slows things down. The option of recovering an artifact from my graveyard was not that interesting when I playtested it. I'd rather use that 2 mana to clamp 2 creatures and draw 4 cards.
I removed one Syr Konrad, the Grim, 5 is expensive to play and Zulaport Cutthroat is more interesting for the price and can also be used as clamp fodder if I need to draw cards. I will surely add 2 more cutthroat when I can get my hands on them.
I am looking for a creature that would cost 1 and that would provide two creatures...like a black version of Doomed Traveler if that exists. Maybe Unearth or Animate Dead would be interesting if I mill myself so much.
The closest I found to a Doomed Traveler that I can include in my deck would be a playset of Myr Servitor...which would hopefully return the ones that I self-milled at the beginning of my upkeep to have multiple creatures for a cost of 1 mana but it won't happen if someone kills the Myr I have in play and they arent black, so they dont trigger Ayara, First of Locthwain
Animate Dead is always amazing. Not only is it disgusting with Supplier since it can res things like Konrad on turn 2 or 3 but it can also res opposing threats when needed.
OOC what don't you like about Supplier? I want to cast it on turn 1 every game so I couldn't imagine being disappointed with them. It's one of the best Black cards that Wizards has printed in years and it's brought an immense amount of speed and consistency to our GY-based strategies. The fact that it pitches to Clamp is icing on the cake because we're ecstatic to pay 2 mana to draw a card and mill 6. I would happily play 8 whereas you seem reluctant to play 4 so something doesn't seem right to me.
It's just that, most of the time, I dont do anything with the cards that it put in my graveyard
Statically you're a favorite to be milling over a relevant threat every other game. After all, assuming 4 Cats and 4 Bloodghasts you're 60% to hit one or more every time that you mill 6 cards. Otherwise, it boils down to "what's a better thing to be doing?" and the answer is "nothing." The only 1/1s for 1 that do things when they die are insignificant trash-heaps like Shambling Goblin. By comparison, the upside of milling over a Bloodghast is utterly insane when your deck has access to things like Oven, Clamp and Ayara. I realize that you don't always hit one, sometimes you hit 3-6 useless spells/lands, but you're a favorite to hit something relevant and that value, albeit inconsistent, vastly exceeds what the alternatives offer. Still, there's always Gutterbones and Bloodsoaked Champion if you're desperate for something different but I would much rather have Suppliers myself.
