Not a fan of any of these cards, really. They screw up any Constructed environment with infect.

I still don't buy the : get 2 poison counters: one mana of any color land being too strong for eternal formats argument. It's a Gemstone Mine that can tap one extra time with the drawback of being worse in multiples.

whats the flavour

I think the body possession is really easy to grok. It's right there in the card name

I like Hospital, because I hate Infect.

4/4

seems unduly swingy

4/3?

Okay, so, I'm about to go through and comment on pretty much every card in this thread, since they're all really cool.

Blur seems like it has the potential for a lot of fun shenanigans. Useful as removal or possibly as a combo card.

Seeker of Apotheosis, someone mentioned possibly making a cycle, and I think that could be pretty cool. I could see some sort of 'ascend' keyword working there. So, it would have "Ascend 7", "Whenever you gain life, if ~ is in exile, put an ascension counter on it" and "As long as ~ is a god, it has base power and toughness 20, flying, and indestructible". I feel like it should be a vampire, since is the lifegain/sacrifice archetype in most sets where that exists, and this guy needs to be sacrificed before the lifegain starts to help. Might be a little slow in its current form; bumping it down to Ascend 4 and making it come back as a 5/5 would probably make it see more play.

Astral Abolishment seems fun, but maybe a bit too powerful. It would be a snap pick in any deck, since it's unconditional removal that can also act as a counterspell.

I really like the paragons, but I feel like the first two abilities being opposites sort of ran out after a while. Which is probably fine, it's your card after all. The infinite bounce is definitely a bit too powerful though, maybe a bounce-edict instead (i.e. "target player returns a creature they control to its owner's hand")

Metakarn seems awesome. The templating would probably be neater with a multikicker though. So, it would cast for , have multikicker , and enter with 2 +1/+1 counters for each time it was kicked. Only difference is that would make it colorless instead of all colors. I guess that makes it not really work as a commander though, which is pretty clearly what it's meant to be used as.

Obsidian Mox seems like a bad idea. Even with that downside, it's still a mox. The only difference is that it's a mox that only goes in decks that can sacrifice it, but in those decks it's as powerful as any other mox would be.

The next card is also pretty overpowered. Yes I am refusing to say it's name. I'm not prudish, but I get easily embarrassed >_>. To me it basically means you spend 4-6 mana and discard a card to cast Emrakul from your hand. As a rule, no card should let you cast an arbitrary spell for free. Even a random spell is pushing it.

Sister of the Hidden Valley seems decent. A dual-color spirit guide that can also be a 2/2 unblockable in the right circumstances.

Skyward Sight... I'd almost say it should cost more. Indestructible and Hexproof already basically means "you can't get rid of this". Even at 4 CMC, it would probably have to be a mythic rare.

Glimpse the Horizon is a pretty good combat trick probably. Very contextual though. It really wants to go in a red deck.

Shrine of Seven Stars... I'm not sure being Legendary is enough of a drawback here, even with it also entering tapped. I suppose it might be, since a 1 mana cost reduction is just about offset by a permanent being legendary, and this is basically Legendary Transguild Promenade without the mana cost.

Barracks is... interesting. I'd have to play with it to know how it works out.

Doubtweaver, Smoke Signal, and Lord of Sorrows seem pretty fun. Easy way to push through mana floods. The only thing I'd note is that with Dakmor Salvage you could intentionally mill yourself out with it if you wanted to do so for some reason. But that's really more hilarious than broken.

I have no idea how powerful Glyphweaver is, but I'd hazard a guess of 'very', since there aren't many creatures with high CMC that don't have abilities. Most of them at least have a keyword ability of some sort.

Crackle is... weird. Probably playable though.

Your version of Sealed Envelope seems good. But... it's basically Mishra's Bauble without the extra info isn't it?

Furious Magamaling seems possibly fun, but it's strict card disadvantage. The "everything gets haste" is probably good enough to make it playable though.

Watcher, Steward (I'm assuming that's what you meant to call it), and Herald seem like a solid cycle of cards. Although Steward is distinctly weaker than the other two. Watcher could be easily triggered with any delve spell, or with something like Relic of Progenitus or even Elixir of Immortality, and Herald just gets +1/+1 each turn even without any sort of combo. Steward, on the other hand, needs sac effects. Which is doable, but seems potentially a bit weaker.

Ichor Factory is something I definitely like. That downside seems like a good one for an 'any color' land.

Hospital, I dislike from a flavor perspective. Which group, in-universe, is using this card? The Phyrexians aren't using it; they don't want to remove poison. But neither are their opponents, since it's very contextual.

Completionist I also dislike. Poison counters are basically a stand-in for damage; you might as well give it "being reduced to 0 life causes players to win the game instead of losing". Laboratory Maniac gets away with something similar because self-mill was already a valid strategy in Innistrad, and has continued to be so in most subsequent sets. Self-poison, on the other hand, is not, never has been, and honestly never should be a valid strategy.

Shadowsoul Invocation seems just generally awesome. I could see it being useful in a lot of situations.

Childhood pet is... weird. I don't really get it. I feel like it should be bumped down to a 3/3 with a benefit when you cast or cycle it (probably life-gain)


Sorry about going on and on a bit. Even if some of these cards are a bit unbalanced, I still think they're really cool ideas, and I wanted to comment on all of them.

I wonder if "Manifest target creature (on the battlefield). Draw a card" would be better.


The reason I didn't make it a Vampire is because Black doesn't care about the hereafter. They're all about living life in the present. To the extent that black can come back from the dead, it's always with a terrible price. See my version of Bahraz.


I feel like Blue needs more oomph. This card has oomph.


Yeah, looking over these, the nonblue one is definitely the best.


I actually wasn't thinking about Commander when I made this! I just think 5-color is really Timmy/Melvin


Yeah. If I were making this now I would make it add .


It's nothing to be ashamed of.

How many cards do you think a free spell is worth? Maybe…

Yo I freaking love the Spirit guides. One of my favorite cards I ever made:

Pyresky Peak
Legendary Land — Mountain
Pyresky Peak enters the battlefield tapped.
(: Add to your mana pool.)
Exile Pyresky Peak from your hand: Add to your mana pool.


You're right. Definitely . You might be right about the Mythic Rare thing too, but I doubt it.


I'm surprised I made this . It's clearly .


I was just on an elegance kick then.


I like the discussion this one generated. Mown is such a genius. He assumes everyone already sees what he sees too before he explains it


Yo the Dakmor Salvage interaction is hilarious. And yeah I think Smoke Signal is the best implementation of this card. if CKY says it's probably too powerful, though, he's probably right. Maybe specify that it has to be a Mountain instead of just a land card?


Yeah but how powerful is a 2/1 protection from creatures tho really.

I mean pretty damn powerful but gamebreaking? I don't think so


I should just let Hearthstone be Hearthstone.


Again, elegance kick. I'm still incredibly proud of this card. It's inspired by the Yu-Gi-Oh! card Jar of Greed, which in my opinion is more elegant than any Magic card.


Oh, yeah, man. This is so much better than Priest of Urabrask are you kidding me? No way this card wouldn't break Dredge-like combo decks.


The cards were mechanically weak: mere vessels for their flavor texts.


In four turns, you lose the game, dude! That's a big deal.


Yeah, these cards suck and go completely against what Poison is supposed to do.


Thanks, man! I like designing Black mythics.


Why the benefit when you cycle it? Isn't the off-color cycling cost unique enough?

I feel you that 3/4 would be better than 4/3, though. We're up against Kalonian Tusker these days.


Sorry I took over a year to respond!

I feel like Glyphweaver needs some reference to Bears. Oh, and for the paragons, you COULD move +1/-0, -0/-1 to black/red and you could give black/green sack a permanent/return a permanent card from your yard to your hand (FWIW, sack a permanent is actually CHEAPER than sack a creature because it gives your opponent more options). And here’s a way to avoid your +1/+1 counters/ -1/-1 counters dichotomy: Tap target creature. It doesn’t untap during its controller’s next untap step/Untap target creature. It gains double strike until end of turn.

Childhood pet is awesome, damn !
