Like most (or even all) of the cards spoiled so far Bangle seems to promote a slightly slower strategy as it shows it’s potential with a little bit of set up. With a bangle already equipped there are a number of ways to transform it into massive face damage either through general buffs, backstab, or just cyclone mask.
Before the pieces lineup though Bangle could allow for some incredibly allowing kiting to occur.
Can we take a moment to point out how much better this card is than Time Maelstrom? Maelstrom cost the same and only lasts one turn while this can be used more than once. Furthermore, this artifact is only a rare while Maelstrom is legendary. And don’t give me that “it’s because Vetruvian has more synergy” nonsense. Songhai has about as much general damage synergy as Vet, if not more.
Cyclone mask is a great artifact to combine with the Bangle as it is arguably the best way to keep your artifacts’ durability, yes. Combined with Saberspine seal (thanks for the mana correction), can result in good damage burst. However, this combination has anti-synergy with the other means of increasing your damage through your general (since they are backstab cards, aside from spear for +1). It would not be advisable to put both of these into the same deck, so we’re likely looking at one or the other.
When evaluating the usefulness of the Bangle + Cyclone combo, you’re more likely to get greater long-term damage out of your artifacts. Attacking at a range and being able to move twice grants great kiting ability, but Songhai’s minions are not the best at body blocking and playing on a 5x9 grid only lets you run so far away. It will largely come down to your match-up to determine how strong this combination will be. Damaing spells and rush minions (especially if they have a body) can pose a threat to keeping your artifacts alive. If you equip these artifacts at an optimal time or against an opponent who has less ability to force them off, you’ll very likely see more damage than by using backstab buffs. But if you can’t keep them on yourself for an extended period of time, you won’t be doing any meaningful damage unless you use Saberspine Seal.
In essence:
You get a minimum of 4 damage each turn you keep your artifacts
(total cards: 2, total mana: 6, total damage: 4x) where x = number of turns
You get +6 damage for each SS you use with these artifacts on
(total cards: 2+y, total mana: 6+2y, total damage = 4x+6y) where x = number of turns and y = number of SS used
It should also be noted that equipping an artifiact in advance puts the combo at risk, since you could lose the first artifact before applying the second. Furthermore, each turn increases the chance you will not be able to maintain the combo as it grants your opponent more opportunities to destroy the artifacts.
In the end, using Cyclone+Bangle allows more counterplay for greater potential long term damage without sacrificing a lot of short term burst (aside from less tools to do so), whereas Bangle+Backstab is more akin to being a “damage out of hand” combo and is extremely unlikely to see use beyond one turn.
I would not claim one is better than the other. They are two different means to and end, and both have their uses. There are still a lot more cards than can benefit this artifact, but I’m not going to go into depth about them unless I have reason too. I already talked too much about this card, didn’t I? 
While it is true that Bangle is strictly better than Time Maelstrom, I’m afraid I must refer to my original post. I really think this artifact would be too strong if Vetruvian had easy access to it. Vetruvian has many preexisting ways to buff their general (Auroras Tears, Falcius, Staff of Y’kir, Time Maelstrom, Wildfire Artifact, Zephyr, Hexblade, Incinera, Spinecleaver, Autarch’s Gifts, Grandmaster Nosh-rak). If they were given an artifact that grants celerity (even if we’re talking about replacing Time Maelstrom), it would be far too easy to abuse for massive damage. Especially so now that they have Gifts (which would be able to auto equip it without needing it in the deck).
At least, there’s something Time Maelstrom can do that Bangle cannot: You can activate your general multiple times if you have multiple Maelstroms. There is some insane burst damage if you can set it up.
take a moment and think “what would it be like if bangle was vetruvian and maelstrom was songhai”
songhai would benefit from the additional spell proc and much of what everyone is saying bangle is good with.
vetruvian would benefit from the additional artifact synergy, especially with autarchs gift, and it would be even easier to get an OTK with sajj.
but that would just solidify the factions identities as the “spell” and “artifact” factions. with little to no room for a reversed or hybrid archtype to be playable at all.
on a side note - does anybody remember all those card design contests? i think i saw this card somewhere
It’s not so much that I think that this card is broken or should be in Vet as I think that Maelstrom needs a rework if they are printing strictly better versions of it for other factions at rare rarity.
Better version just go out and say the hipster word of power creep. It’s not even in the same faction thus reworks isn’t needed and shouldn’t be brought up. It’s a card that branches out songhai from just the spell centric faction.
This card is trash. People just get excited about things because they’re new.
As a Vet Player I’m actually fine with Songhai having the Celery Bracelet simply because Songhai doesn’t have a means for equipping the thing without using their mana not to mention it takes up space in their deck(s). Besides we have Autarch’s, which can potentially put 9 Mana’s worth of artifacts on the general, Cleaver and Hex, for 6 Mana without taking up more then three spots in our deck at most.
Well well well well well. How about that.
Bonus points for Saberspine Seal, Obscuring Blow or Ethereal Blades.
In songhai I would wager time maelstrom would be stronger than this artifact since it is a spell, meaning it can be discounted (although there could be a card that reliably discounts artifacts in latter expansions). Every single discount counts since it is another turn earlier that you can get your OTK combo off.
However in Vetruvian, yeah the artifact is stronger just because it procts aurora’s tears. Since songhai is more spell based, having it being able to support a shell of arcanyst shenanigans (i.e. adjudicator, four wings magi, owl beast sage, avatar), I would wager time maelstrom is better via synergy.
You know, I was originally a bit salty that Time Maelstrom was reprinted as a rare Songhai card. Then I made this meme and all is well again:
Technically cpg has been pushing for a general based songhai deck for quite some time but whatever you say goes mate
I believe, there was “Mask of Celerity” in Songhai in the early days of Duelyst. 3 mana +1Attk and Celerity. Now it is almost back.
BTW, I’m now completely sure that songhai will never get anything reliably buffing general attack by more than 1. Cyclone mask was limiting design space, but this makes the forementioned design space tight as hell.
But you can buff general with ethereal blades AND saber spine seal and it’s a 5 mana combo with this artifact so they already have something to buff their general.
mist walking+ this + mash of shadows = annoying damage & undamaged artifacts
hehehehehehehehehahaahahahahahahahahHAHAHAHAHAHAHAHAHA!!! Yes! YES! YESSSSS!!! MOAR! THE POWER!!!
Songhai:
That feeling when you feel like you helped influence CPG’s decision to this. 
But… blinding? But…
Well anyway, cool artifact! 
Songhai, coming in with the BoBS!
