Tarkir: Dragonstorm features a lot for a single set. We have tri-color wedge clans, previously subjugated by their dragonlords in Dragons of Tarkir, waging war amongst their dragonlords, dragonstorms running wild, new spirit dragons to add even more chaos to the mix, and dragons, many dragons. Dragons everywhere. With that many dragons in a single set, we have a simple mechanic to ease these 5+ mana value cards into a regular deck curve: Omens.

Omen is a new split-card type mechanic present in Tarkir: Dragonstorm. I'll be your guide to understand the ins and outs of this new mechanic, its rules, and which are the best omen cards. It’s time to read the omens, and decide which bring ill-fate, and which ones will lead into the right path.

How Do Omens Work?

Omen cards are very much like split cards. You have a main creature spell on its right side, that’s always a dragon, and you can cast it as usual. You can also cast the omen part on its left side, which is always an instant or sorcery, but after it resolves it shuffles itself back into your library. So you can decide between a nice flier and a good spell, but not both.

Let’s take a simple but effective example to show off this mechanic. Twinmaw Stormbrood is a 5/4 flying dragon for , that when it enters, you gain 5 life. Not bad. You can also pay to cast its omen side, which is Charring Bite, and in this case you’ll get Roast, 5 damage to any non-flying creature. When you cast Charring Bite, you shuffle the card back into your library, so you can draw it later and then decide if this time, you’ll go with the dragon or simply use the removal spell another time.

The History of Omens in MTG

Omens first appeared in MTG on Tarkir: Dragonstorm (TDM) in 2025, in 13 designs across all colors. Like the adventure mechanic before it, omen cards don’t exist in a vacuum; they are part of another card and even share the same frame as the adventure cards. And in the case of TDM, omens are always a part of a dragon card.

In TDM, we have a cycle of monocolor common dragons with omen, a cycle of uncommon dragons with off-color omen abilities, and three mono-color rares. It’s interesting to note that Tarkir: Dragonstorm Commander (TDC) doesn’t have any omen cards, so barring an Alchemy card or two, we’re not seeing omens again anytime soon.

What’s the Mana Value of an Omen?

The mana value of an omen card is always the printed cost of the card, or in other words, the cost you pay to cast the dragon. It’s only different when you cast the omen, and only while the omen is on the stack.

Let’s take Disruptive Stormbrood as an example. This is a 5MV card in all game zones: graveyard, library, hand. and the stack if you’re casting it for . You may also cast Petty Revenge for , and in this case, it will be a 2 MV spell while it's on the stack.

Can You Cast Both Halves of an Omen Spell?

You can cast either the omen half or the dragon half, but not both at the same time, as you would with a fused split card. If you cast the omen card and it resolves, the card is shuffled back into your library. If you cast the dragon part and it resolves, it enters as a creature, and you can’t cast the omen anymore once it’s in play.

Do You Still Shuffle Away an Omen if It Gets Countered?

You don’t. If the omen gets countered, it goes straight into your graveyard. It’s very much like an adventure card in this regard. The omen only shuffles itself back into your library after resolving.

Does an Omen Count as an Instant/Sorcery in Your Graveyard? In Your Library?

No. In all zones, cards with the omen mechanic are considered dragon creature cards. That’s valid for all characteristics including name, type, power/toughness, color, and mana value. A tutor like Mystical Tutor can’t be used to tutor for an omen card.

Do Omens Count as Dragons?

They don’t. The omen mechanic is only present on dragon creature cards, but when you cast an omen, it’s not considered a dragon spell. You won’t trigger effects like “whenever you cast a dragon spell” when you cast an omen. It’s interesting that you can use dragon tutors like Sarkhan's Triumph to functionally tutor for a spell, but this doesn't work in reverse. So Mystical Tutor won’t fetch Bloomvine Regent, even if you try to tutor for the omen part in Claim Territory. You can do that with Worldly Tutor, though.

Omens vs. Adventures

Omens and adventures share the same card frame, so it’s very easy to mistake one for another. The key difference is that, whenever you cast an adventure spell and it resolves, it exiles itself (the card goes on an adventure, according to MTG rules). While it’s on an adventure, you can cast the rest of the card, be it a creature or an enchantment. So, adventure cards are a natural two-for-one. Omen cards, however, shuffle themselves after resolved, so you can’t get the dragon card naturally.

It’s also easy to confound because there are plenty of adventure cards that are also dragons, like Decadent Dragon and Young Blue Dragon.

Omens vs. Split Cards

In this regard, it’s easier to think of omens as your traditional split card. You either cast the left half or the right half, but not both. The biggest difference is that you have to add the two halves of a split card when you evaluate their mana value, while omen cards only count the dragon’s MV.

Best Omen Cards

#6. Runescale Stormbrood

Runescale Stormbrood is a nice addition to dragon decks, or to spellslinger decks. Chilling Screech acts as a counterspell that’s effective early game, and when you cast this dragon, it’s easy to attack with it as a 4/4 or 6/4 even. Play this if you’re expecting to storm off, or with dragon synergies.

#5. Disruptive Stormbrood

Disruptive Stormbrood’s value comes from the fact that it’s flexible, either as a small creature removal spell in Petty Revenge, or as a flier that acts as a Reclamation Sage, and you can blink it for value or reanimate it later. You’re not sad if they bounce it, so you can get another go at a removal effect.

#4. Whirlwing Stormbrood

Whirlwing Stormbrood is the new Hypersonic Dragon, one that also has flash, and giving flash to your dragons is nice. It’s a weak card overall, so you’d better rely on the ability. Giving three +1/+1 counters is very situational, and outside of Simic +1/+1 counters deck, it’s not a good effect. It gets a lot better when you have cards like Fathom Mage or Evolution Sage that can convert the +1/+1 counter benefit immediately.

#3. Marang River Regent

Marang River Regent is strange to evaluate, except in Limited – the card is bonkers there. In Constructed, it’s a massive 6/7 flier that bounces two nonland permanents, so you can have strong value with your own sagas/planeswalkers, or disrupt what they’re doing in a big way. But at the same time, it lacks something like ward or flash. Coil and Catch is also a good effect, but Rain of Revelation is hardly playable on its own. I’m guessing that neither card is good on its own, but it’s flexible enough on its own or with other dragon synergies, that it will be good.

#2. Scavenger Regent

I’m a big fan of -X/-X modal sweepers like Exude Toxin. You can choose which toughness of creatures you need to swipe, and you can keep your dragons, like you would with Crux of Fate. This is the omen where the dragon excites me least, but even then, it’s a good on-rate dragon with a strong ward effect, so there's no problem casting Scavenger Regent on turn 4 either.

#1. Bloomvine Regent

Bloomvine Regent strikes me as the easiest omen card to include. You have a sort-of Cultivate if you cast Claim Territory, adding redundancy to early game ramp, or you can have a dragon that is fairly sized as a 4/5 flier that gains life to offset some hits you’ve received. More dragons, more life, and don't forget that you can surround it with changelings.

Wrap Up

Omen is an interesting way to create modality, in a way that promotes riskier gameplay than adventure. After all, you’re not guaranteed to get the creature side of the card, so it’s not a pure value mechanic like adventure is. The mechanic is themed around dragons in this set, as befits a set like Tarkir: Dragonstorm. That said, you can fit this into other sets, either with the same name or another. So, I’d be surprised if omens were not used elsewhere.

It’s also interesting that WotC took a safe approach with these cards, so even the more powerful cards are not obvious inclusions in Constructed decks. If they wanted to push the power level, the Commander precons could have had a power outlier, which is not the case.
