Strong/Staples:
None.
Interest:
Skyserpent Seeker (U): Not exactly Baleful Strix, but closer than I would have ever expected. It functionally draws you (a slightly worse) Explosive Vegetation that also makes it slightly bigger. It can curve Elf, Seeker, Activate, 7 Drop.
Veteran Beastrider (U): Above-rate body that pseudo grants your whole team vigilance and is an acceptably costed anthem effect. I think I really like this card.
Similar:
None.
Unique/Synergy:
Boosted Sloop (U): Not exactly peasant’s Smuggler’s Copter, but it triggers on just attack and gives a discard outlet to Blue-Red.
Broodheart Engine (U): Can you still pay 2-mana on Turn 2 for a card that doesn’t affect the board? This gives you repeatable surveils and “draws” you a Zombify. But in a deck that wants to be 17+ creatures, would you prefer Broodspinner or Nyx Weaver?
No Interest:
Apocalypse Runner (U): I think you wouldn’t play this just for the tap ability and the vehicle half is worse than an unplayable draft common from Kaladesh (Irontread Crusher).
Boom Scholar (U): Too narrow in 99% of cubes.
Cloudspire Coordinator (U): Unless you’re supporting vehicles, Veteran Motorist is very similar.
Cloudspire Skycycle (U): Aerie Auxiliary is just better in most cases.
Dune Drifter (U): Graceful Restoration is likely to be better in most circumstances.
Embalmed Ascendant (U): I think you’d rather have Elas il-Kor, Sadistic Pilgrim.
Gastal Thrisllseeker (U): A great enabler for Speed, but I don’t think you’re going to be able to support it in most peasant cubes.
Guidelight Pathmaker (U): The vehicle isn’t worth 4-5 mana even if it provides a tutor.
Haunted Hellride (U): It’s a mediocre enhancement “enchantment.”
Haunt the Network (U): The floor isn’t great for 5-mana and Blue-Black is a very hard section to break into.
Lagorin, Soul of Alacria (U): A lot of work to slowly make a big flyer.
Rangers’ Aetherhive (U): Too narrow in 99% of cubes.
Rocketeer Boostbuggy (U): I don’t love combining a bad Goldvein Pick with a 5-mana 4/3. Wildfire Wickerfolk just seems better.
Thundering Broodwagon (U): Too expensive and too pip-intensive. I’d rather play Back for More or Spiritmonger.
Voyage Home (U): Three artifacts makes it fine. Anything less and it’s rather bad.
