Strong/Staples:

None.

Interest:

Wingblade Disciple (U): I think this is better than Xerex Strobe-Knight. I also think it’s probably worse than MIschievous Mystic, but you could probably run both and it’s in a much better color than Clarion Spirit.

Similar:

Constrictor Sage (U): I think I prefer the better body of Juvenile Mist Dragon or bouncing the creature with Spikeshell Harrier, but this does add a graveyard synergy.

Unique/Synergy:

Veteran Ice Climber (U): I think this is a self-mill card, not an offensive mill card, and considered that way, I kind of like it. It blocks 2/x’s and pings and mills repeatedly. Not sure most Blue decks are playing enhancements and not sure it outperforms Shoreline Looter and Looter il-Kor.

No Interest:

Aegis Sculptor (U): Ward is nice, but these type of “grow” creatures generally disappoint. Also, most decks that will have enough graveyard fodder to let this grow decently are going to want to use their graveyards for something else.

Agent of Kotis (C): Blue scavenge is unusual. But neither the body nor the ability are priced competitively.

Bewildering Blizzard (U): I think I like Behold the Unspeakable more.

Dirgur Island Dragon (C): As a new card format, omens are hard to evaluate. Thinking of this as a split card, Tap/Draw isn’t a great card for 2-mana. And we have better 6-mana flyers. I’d rather have something like Sapphire Dragon.

Dispelling Exhale (U): Worse than Mana Leak and for Quench we have better upside with Phantom Interference or Lose Focus.

Dragonstorm Forecaster (U): Neither of the searched cards is particularly good, so I don’t think this is worth considering.

Essence Anchor (U): If I wanted repeatable surveil, I’d rather play Mindwhisker. The build-around upside here seems overly finicky, but we are slowly amassing a set of cards that care about cards leaving your graveyard.

Focus the Mind (C): The ceiling is decent, but I think the floor is too low and we have lots of instant speed draw at 4- and 5-mana.

Fresh Start (U): I would prefer So Tiny or Unable to Scream.

Highspire Bell-Ringer (C): The body isn’t good enough for what is functionally a conditional mana-dork.

Humbling Elder (C): Functional reprint of Cogwork Wrestler.

Iceridge Serpent (C): We just had Spikeshell Harrier and this is pretty much strictly worse.

Kishla Trawlers (U): Pretty similar to Tenacious Tomeseeker and I think it’ll play more finicky.

Ringing Strike Mastery (C): Singing Bell Strike is a playable card, but not great, and I think Bind the Monster is probably better in most decks that want this effect.

Riverwalk Technique (C): The two modes are a little too similar and I think you’d prefer something like Spellgyre or [Unsubstantiate]].

Roiling Dragonstorm (U): Chart a Course is likely better in most Blue decks as it can be actual card advantage, it’s an instant or sorcery, and its upside is likely easier to trigger.

Sibsig Appraiser (C): The graveyard synergy is nice, but the power just doesn’t compare to Serum Visionary. Would probably be better as a 1/3 a la Sea Gate Oracle.

Snowmelt Stag (C): I think being a 5/2 on attacks is worse except when you’re activating the ability, which is 7-mana! Not sure this is that much better than Wormhole Serpent.

Spectral Denial (U): I think Condescend probably has more often useful upside (or Stubborn Denial if you really care about 4-power matters).

Temur Devotee (C): Limited mana-filtering is likely worse than conditional attacking.

Unending Whisper (C): I’d like it a lot more if it was an instant. But otherwise I think you’ll prefer Think Twice or Radical Idea.

Ureni's Rebuff (U): I like Silent Departure more even if this can be pseudo-flashbacked for cheaper. Being 1-mana is a huge deal.

Wingspan Stride (C): I don’t understand the play pattern of this card (maybe to support double-spelling), but it’s a strictly better Arcane Flight.
