There were a couple of cards that I submitted to the custom cards subreddit that were later printed almost exactly like I posted them. I mostly remember Foundation Breaker (mine was 2GG cost and 3/2) and Damn (mine was 1BB // 3WW for the costs)

Definitely pauper. There are some staples that are expensive, like Snuff Out and Spellstutter Sprite, but you can build plenty of meta decks and brews without them. It's also very fun, I definitely recommend it. Otherwise, you can always try to proxy decks from other more expensive formats like legacy and modern. They are also fun to play imo.

I mostly dislike it for requiring outside game pieces to function, making it overly complicated, all for trying to fit the lore into the mechanics too hard. Similar to the problem I have with dungeons and initiative.

This looks fantastic. I'm kinda new in the fediverse, but I really hope this gets off if reddit doesn't back off their API policies.

For now, I have a suggestion, which would be creating a community for cube, and a question, which is: When I try to create a post, there's a text box with URL before it, and I'm just puzzled for what should I put there and what purpose it serves. Thanks.

Stitcher's Supplier is also such a great card in commander. I've had tons of golgari or BGx graveyard decks using it and its buddy [[Satyr Wayfinder]].

That's a cool and clean design. I agree with Mike that this could cost less mana, being a conditional cantrip and needed heavy deckbuilding requirements to do anything more than that. 1 or 2 mana seem reasonable as is. Maybe it could be at 2 or 3 mana if it just drew the card with no conditions asked.

Something that has been on my mind for quite some time, and that I would consider learning to mod just to make it happen would be discretizing the potion and enchantment system. By that I mean that instead of having the ability of making potions that restore 50 health, 51, 52, etc., depending on how high your alchemy, you would only have discrete values, eg. 25, 50, 75, 100, 125..., or whatever you choose, and you jump from one to the next instead of going through all the intermediate integer values.

That would avoid a lot of inventory clutter that you get from making potions and leveling alchemy in the process. I remember I've seen a mod that does this once, but it didn't seem very active and updated.

I mean, that's kind of expected of abilities that would only benefit their target by themselves, without politicking or other synergies you can't get benefits from them. What would you want them to do, give you a benefit if you targeted your opponent/opponent's permanents/cards with them? The only problem with that is that Kenrith has too many abilities to fully write this effects down. I guess it could only do that part where you benefit an opponent for a benefit to you too, but that would be a significantly different design.

There's [[Generous Patron]] and [[Willbreaker]], which are great payoffs for targetting your opponents creatures with the green ability. The blue ability is also used as an infinite mana sink to mill your opponents out.
