was given the axe in Modern. Some players have been quick to look for replacements within Cascade shells, turning to
Ardent Plea

or even
Bloodbraid Marauder

Delirium — This spell has cascade as long as there are four or more card types among cards in your graveyard.

Put the exiled cards on the bottom in a random order.)

decks in Modern, perhaps these archetypes won’t be quite as dominant as they have been. This could theoretically open the door for a handful of decks that were completely held down by these Cascade variants.
One strategy that fits this mold that has been almost nonexistent over the past couple years is
Gifts Ungiven

Gifts Ungiven Core

The main goal with Gifts Ungiven Storm is to cast the namesake card while you have a way to reduce the cost of your Instants and Sorceries in play. Historically, these cards have been
Baral, Chief of Compliance

Whenever a spell or ability you control counters a spell, you may draw a card. If you do, discard a card.
and
Goblin Electromancer


To solve — You've cast four or more instant and sorcery spells this turn. (If unsolved, solve at the beginning of your end step.)
Solved — Whenever you cast an instant or sorcery spell, draw a card.
. As we will get to later, this is a huge change in this deck’s favor that gives it a better shot at winning in attrition-based matchups.
In either instance, winning the game becomes trivial when you add Gifts Ungiven into the mix. With three mana available after resolving Gifts Ungiven, you can typically win the game that turn. To help make sure you have extra mana reliably, this deck makes use of
Desperate Ritual

Splice onto Arcane {1}{R} (As you cast an Arcane spell, you may reveal this card from your hand and pay its splice cost. If you do, add this card's effects to that spell.)
,
Pyretic Ritual


Draw a card.
. With Baral or Case in play, each Ritual nets you two mana and Manamorphose nets you one mana (which notably can be blue).
As such, a common play pattern is to play Baral on turn two. If you get to untap with it, you can cast either two Rituals or a Ritual and Manamorphose, and follow up with Gifts Ungiven. Assuming you hit your Land drop, you will have at least three mana floating when you cast Gifts Ungiven. Now, simply search for one of each Ritual, Manamorphose, and
Past in Flames

Flashback {4}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
. Whether your opponent gives you Rituals or Past in Flames and Manamorphose, because Past in Flames has Flashback, you will get to cast Past in Flames either way.
From there, you get to recast all of your Rituals, use Manamorphose to filter into blue mana, and cast Gifts Ungiven once again. With a big enough Storm count, this time, you can find Grapeshot and dome your opponent for a ton of damage.

New Additions

Where things get interesting is with the inclusion of Case of the Ransacked Lab. Case acts as a combo piece just like Baral does, maximizing your Rituals and making it easier to win via Gifts Ungiven. While it costs one more mana than Goblin Electromancer, it is much more effective in a wide variety of matchups.
First and foremost, Case doesn’t die to Creature removal, something old Storm lists were surprisingly a bit vulnerable too. Considering that removal has gotten significantly more efficient in recent years (think

isn’t always a reliable way to protect your cost reducers.
Additionally, in spots where getting to a full Grapeshot kill is tough, such as against a bevy of discard spells from the opponent, it’s not unreasonable to Solve the Case and turn all of your future Rituals into cantrips. Imagine casting a couple Rituals, a cantrip, and
Empty the Warrens

. Now, not only does your opponent have to contend with your big board of tokens, but they also risk falling behind on the card advantage front.
Speaking of cantrips, being able to add

is a big deal. Preordain is very strong and helps make finding Case or Gifts Ungiven much easier.

Strengths and Weaknesses

In general, Gifts Ungiven Storm still has its bevy of tough matchups to watch out for. Cascade decks are far from dead, and they are capable of presenting a quick clock backed up by Force of Negation. The presence of

combo and Rakdos Scam can be a bit problematic. Izzet Murktide seems like the nightmare matchup, presenting a great mix of efficient threats and plenty of counter magic to make it nearly impossible for you to find your footing.
This doesn’t even take into account graveyard interaction and other forms of hate that have historically been effective against Storm shells. Still, this isn’t to say there aren’t some things going for the Storm deck. Other combo decks like Golgari
Yawgmoth, Thran Physician

Pay 1 life, Sacrifice another creature: Put a -1/-1 counter on up to one target creature and draw a card.
{B}{B}, Discard a card: Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
combo and Amulet Titan don’t play the widest range of disruption for the matchup, and you can often combo kill them before they can do the same to you. Slower strategies like Tron that need a bit of set up time can really struggle, too.
This deck attacks from a rather unique angle, so if you’re not prepared for it in some capacity, you may have a hard time. Additionally, this archetype is a rather budget-friendly option compared to the rest of the decks in the Modern format. Even with the pricy manabase and playset of Flusterstorm in the sideboard, you can purchase the entire deck for under $400.
This is a solid deal in an expensive format like Modern. With this in mind, whether you’re a Storm aficionado looking to dust off the cobwebs on your beloved Modern deck or you’re simply looking for something intriguing to play in this stale metagame, definitely give this deck a shot.
