Secrets of Devasarva

Thanks. Many of these suggestions are things I would never have noticed. Keep em coming! I'll adjust as needed.

Thanks again for the additional feedback. I'll give some updates on the cards you've mentioned.

- Avian reconnaissance: Agreed that it's a bit weak for 2cmc. I changed it to create two 1/1 fliers instead for 3cmc. That makes the secret mode more relevant and makes the card comparable to other effects that create two 1/1 flying tokens.

- Azva of the dawn: I don't think it's too strong for an uncommon, but it's definitely too strong for 5cmc. I had already adjusted it to 6cmc before you had mentioned it. I'll see how it plays in testing before making further changes.

- Balance seeker Garuda: changed it from 4/4 to 3/3. Still pretty strong.

- Banamati soul priest: I used Plaguecrafter as an example of the rules text. "Each player sacrifices a creature or planeswalker. Each player who can't discards a card." I had to change the wording to apply to only one player, but I think it is close to what WotC would use.

- Celestial Confinement: Couldn't find space for this in uncommon. I added flash to the card. That makes it stronger than seal away. I can't justify reducing the mana cost further, so I'll have to add additional effects if flash isn't good enough on its own.

- Crystallize: My aim with this card was to be somewhat situational. It can either give you a strong blocker (while keeping your creature alive), reduce incoming damage (always useful), or allow you to get some unblockable damage in with a skulk creature.
There are a small number of cards in the previous sets that check toughness for various reasons, so there is some relevance there as well.

- Deva offering: I agree that I probably don't need two of these in the set. The black one is meant to be a slightly weaker version of Village Rites (which I think is overpowered). I wanted to white one to be even weaker than that, hence the limited sacrifice options and increased casting cost. Still, drawing two cards in white is pretty rare, and I used a similar effect in one of my previous sets that involved removing +1/+1 counters as an additional cost. I looked at other "offering" cards across Magic's history and the commonality is "destroy something, gain life equal to its cmc". I don't have artifact destruction in white, so I might change it to that. White still needs at least one draw effect in common, which is otherwise missing without this card.

- Devious archivist: This effect hasn't been used by WotC in a long time, but the previous Devasarva sets have a strong monocolor theme, especially in black, so this card is meant to interact with those.

- Entice: I decided to change it to XG and put the tutored creature directly onto the field. With the sacrifice in the cost, I think this is reasonable, but it might still be too cheap. I looked at Chord of Calling and Eldritch Evolution for inspiration here. Might have to make it XGG if it's too powerful.

- Eye of wonder: I can't remember what cards I based this wording on, but they were old - really old. It seems that modern cards that reveal a single card always do so randomly, so I went with that. Originally I wanted this artifact to be anti-secret, but I ended up making it a mill card with the following abilities. "T: Target player reveals a card at random from their hand. That player mills cards equal to the revealed card’s converted mana cost. 4, T, Sacrifice Eye of Wonder: Each player discards a card at random. Then each player mills cards equal to the total converted mana cost of cards discarded this way." Might be completely busted in a multiplayer game, but I need to test it to find out.

Forgotten factory - I see what you mean. I removed the mana gain effect and reduced the card's cost to 5cmc. It's already strong without the bonus mana, so we'll see how that goes. What I have found is that by the time you get 5 or 6 mana to cast this card, you don't have that many cards left in your hand to discard, making its initial effect pretty slow and weak until it gets going.

Frilled ajjana - You're right that the first effect feels blue. I mostly wanted to accentuate the second ability by somehow keeping this creature alert. I just gave it vigilance for now while keeping the second ability. I might make it -2/-0, but that might make this thing too strong. 

Gaja pacifist - The token isn't unique as a flier, but the fact that it's a Bird matters a lot for the previous sets with a strong tribal theme. Plus the art was too perfect to ignore for the card's effect!

Golem forger - You're right about "gains" but I'm not sure what you mean about the mana ability. Mana costs always come before tapping.

Secret is definitely a rules nightmare. I like the way it plays though, so I've left it as is. Realistically, the cards need to be cast from somewhere other than the battlefield to make the game rules work, so if anyone asks I'll just say you exile the card before you cast it. I'm still messing around to see if I can squeeze it into the reminder text without adding a lot of lines.

Scrap golem - Cool design
Secret tokens - Probably these are not really tokens, but just enchantments. See morph "tokens" as reference
Spellcleave - Probably I wouldn't make a copy spell as common
Spiritual guidance - Very strong tempo play! Maybe too strong if compared with similar effects (Drag Under, Repulse, Force Away)
Stoneflats platou - I feel like the flip condition for this cycle is too loose: probably you can have 3 mana at turn 2 very often with some 0 cmc artifact, or at least 4 mana on turn 3 in a color that typically doesn't offers ramp. What about change it to controlling two?
Territorial confrontation - Super flavorfull!
Time of blood - Impressive art. The wording should be "activate" instead of "play", I guess. Moreover I fell like cmc 3 is too much for this narrow effect. I would put it at a single red mana.
Titans' awakening - Cool!
Traumatic memory - Nice idea to cycle your card in order to cast opponent card.
Tsarati reconnaisance - The idea is good, but I have the feeling that this can become too strong on a one-mana enchantment. I would change it to a creature to make it less oppressive
Uluka visionary - I would love to play this in my mono ninja U pauper deck!
Vajra of balance - Correct wording is "T, pay 2 life" and not "pay 2 life, T". Nice design no matter what.
Vasumati heiress - This ability is cool, but it's the kind of effect I prefer to see on a rare personally.
Volcanic viper - This feels extremely strong: a 3/1 haste for 2 is already pretty strong (Pyromantic pilgrim costs 3). Add two abilities to it and you get almost a mythic
Zazvata nestling - I guess its a Phoenix and not a Pheonix. Interesting too see a 1/1 flying for R.
Zriya - Her adventure is interesting but surely abusable in some storm deck. Probably this will be an insta-ban in modern and legacy

That's all my feedback! I'm impressed to what I've seen on this set, and I found it inspiring for my future works. Keep it up!

Sure. I'll do it when I get to work today.

Thank you! Just to know: have you printed these sets?

I'm curious about the number of cards you printed. For example, how many copies of each commons? Or you just printed singletons for a "cube" experience?
