So scry 2 and draw 2 with a slight upside in most cases but over multiple turns. I am interested but I am not sure this is because of the design or because the card is actually good.
Hydra's Growth is a more fragile and fair version of Kalonian Hydra. It's even more 'all in', so I assume most people (including me) won't like it in their cubes. But it's certainly a powerful card that will win the game if it's unanswered for a few turns, especially on a creature with evasion. On the other hand people who would play this would probably play Curse of Predation as well, and that is a way better card with a similar effect.
I like Chainweb Aracnir. Nice payoff for graveyard/self-mill decks. The one drop isn't useless for a slow deck like that and later you get a 4/5 reach that can kill pretty much any flyer your opponent can possibly have on etb. Will add that one.
Medomai's Prohecy is hard to evaluate. You are bound to play the card you named during stage 2 or the card will be almost wasted, which could lead to bad situations quite often I imagine.
Omen of the Sea is nice with any permanent bounce/flicker. Makes it hard to get blown out and is one of the better CA targets available. Also just a reasonable card, though it doesn't work in spells matter like the rest of the cantrips.
Chainweb Aracnir seems strong. A cursory search gives me 20 x/1 flyers in my cube ignoring spirit/thopter makers. And it's escape is a Nessian Asp without monstrous that etb plummets, which is just a good card. Getting 4 other cards in yard isn't particularly hard either. Only downside I can see is it doesn't work if you draw it late and need a beater immediately.
Medomai's Prophecy seems good, but probably top awkward. If you top deck it and bottom 1 you need to hold what you topped for the turn to get the draw. Scry 2 draw 2 for 2 is pretty tempting though.
Is Omen of the hunt relevant for the illusive Enchantment deck? I suspect that archetype will receive a fair few upgrades in the set, but perhaps Wild Growth, Utopia Sprawl, Gift of Paradise are more than enough options for enchantment-based ramp already? The option to scry it away is nice, and flash is also useful in simic, as those decks often both want to play at instant speed and tend to be splashing...
I am quite hopeful since each of Devotion, Escape, and Sagas is a mechanic I quite like. However, Daxos is definitely not something I would personally really see myself adding. Even though it could be decent enough as a ground clogger in a life gain stall.
Well, so far this set truly sucks. There is still a lot to spoil, but an uncommon like The Binding of Titans is basically a really bad version of a mediocre common from another set (Grapple with the Past), which is not a good sign. And it's unlikely we'll get any broken devotion cards so unless your cube is based around mono color decks most of what we'll get for that mechanic will be out of question. Just a few weeks ago I cut Gray Merchant, and I doubt we'll get anything better than that.
With a heavy graveyard theme, I like Cling to Dust. It hits the theme on two levels by hating the grave and having escape. It's a sweet card, but most people would probably underrate it and think it was strictly sideboard fodder.
The Spider Confirmed but also... Reverent Hoplite which is also pretty amazing. White has perminate based removal and lots of pips.
Hmm still Mire triton seems just a step below my other 2 drops also I have a thing about 1 toughness creatures being bad (I have so many 1/1 tokens and 1/1 token hate), I'll see what my players think. I have a cube schedualed just before Theros BD comes out.
archon of falling stars looks pretty strong as a 6 mana 4/4 flying with a death trigger that can be pretty relevant. getting back a removal spell or a big enchantment creature (if you run stuff like the archetypes) is good value.
stinging lionfish is interesting, especially as a 2 mana 2/1. absolutely no idea how good it is though. at very least it can be a great defensive creature.
drag to the underworld is an efficient removal spell, but not super good in control in theory, so honestly might be a good addition just as a removal spell that isn't a braindead autoinclude.
nyx herald as a 3/4 trample for 3 alone is pretty strong, but i'm pretty sure that's all it's ever gunna be. i don't think it needs to spread the buff though, being ahead of the curve is strong enough.
blood aspirant is expensive and slow, but it actually does a ton at once; grows itself, pings, and forces through damage. probably too slow for us but i wouldn't be surprised if it's actually super good.
rebirth for glory is a strong 2 for 1 but i don't think its value is maximised in cube. getting back a dude + a pacifism seems great though.
pharika's spawn's escape side looks absurd. i think this is definitely cubeable as a pretty excellent late game grinder.
chainweb aracnir still looks awesome to me. probably still the standout card along with the gorgon.
reverent hoplite looks as terrible as its predecessor in og theros.
mire triton does a lot of small things well, and is also a deathtouching 2/1 for 2. solid body, solid effect.
devourer of memory is super interesting and honestly looks strong af. i dig how self mill isn't strictly golgari now, since other colours didn't really have that much payoff before.
escape velocity is a pretty cool fires spinoff. not sure how it compares to reckless charge, or even just fires in general.
brine giant gives pillowfort a good card if anyone supports that?
daxos looks like pretty good value, and a great defensive creature. i think vigilance would be too much to ask for but man how good...
Leonin Relic-Warder + Animate Dead/Dance of the Dead + Soul's Attendant or Blood Artist or Zulaport Cutthroat or Falkenrath Noble or Syr Konrad or Hissing Iguanar or Goblin Bombardment
- Fiend Hunter + Oblivion Ring/Journey to Nowhere + Leonin Relic-Warder + Soul's Attendant or Blood Artist or Zulaport Cutthroat or Falkenrath Noble or Syr Konrad or Hissing Iguanar or Goblin Bombardment
Nyx Herald probably isn't good enough, but it's close enough that I'll wait until the end of spoilers to decide. 2-3 strong/repeatable auras and a few aggressive green enchantment creatures would make it quite strong.
Blood Aspirant notably triggers on permanents, so clues, food, sagas, and fetches all boost it, not even going into specific cards. Doesn't seem overly unreasonable considering it gives decent utility.
Pharika's Spawn is midranged filler. A 4 cost 3/4 is incredibly passive, and the escape isn't even particularly good for a 6 drop. If you want to grind out value there are easier ways.
Mire Triton is playable, but self milling 2 is often too minor to be worth anything outside of devoted GB graveyard decks. Additionally, Vampire of the Dire Moon fills a similar niche, but I'm not sure which one is better.
