Split second<\/strong> is a Magic: The Gathering keyword from Time Spiral (October 2006). While a spell with split second is on the stack, no player can cast spells or activate abilities that aren’t mana abilities.<\/strong> In plain terms: nobody can respond to it. Krosan Grip destroys the artifact and the owner doesn’t get to activate it, protect it or counter the Grip first. That makes split second one of the cleanest ways to stop an opponent’s trick at the exact moment it matters.<\/p>\n\n

For almost twenty years split second lived on a short list of Time Spiral instants. In October 2026 that changed. Samut, Tyrant of Naktamun<\/strong> from Reality Fracture is a two-mana blue commander that gives every<\/em> instant and sorcery you control split second. Your Counterspell can’t be countered back. Your bounce spell can’t be answered with a protection spell. We counted what that switches off: 3,754 Commander-legal instants, 607 flash cards and every activated ability that doesn’t make mana<\/strong>. Only a handful of cards still get through, and we list all 10 of the ones that matter.<\/p>\n\n

This guide covers how split second works, what you can and can’t do in response (the part most players get wrong), every split second card with its real Commander play count, the three cards that grant it, legality in every format, and a $70.21 budget Samut, Tyrant of Naktamun deck<\/strong>.<\/p>\n\n

What is split second in MTG?<\/h2>\n\n

Split second is rule 702.61 of the Comprehensive Rules. Rule 702.61a defines it: “As long as this spell is on the stack, players can’t cast other spells or activate abilities that aren’t mana abilities.” It is a static ability, and it only does anything while the spell is on the stack. Once the spell resolves, or leaves the stack some other way, it stops mattering, and players can cast spells and activate abilities as normal again before the next thing on the stack resolves.<\/p>\n\n

Every card with the keyword carries the same reminder text: “As long as this spell is on the stack, players can’t cast spells or activate abilities that aren’t mana abilities.” The design point is the word response<\/em>. Most instant-speed interaction in Magic works by responding: you hold priority, cast something on top, and it resolves first. Split second takes that option away from everyone, including you.<\/p>\n\n

Split second was the signature mechanic of Time Spiral and Planar Chaos. The cycle of “Sudden” instants (Sudden Shock, Sudden Death, Sudden Spoiling) came from there, along with Krosan Grip, Trickbind and Angel’s Grace. Wizards brought it back in small numbers: Sudden Substitution (Commander 2019), Sudden Edict (Modern Horizons 2), Legolas’s Quick Reflexes (The Lord of the Rings Commander), V.A.T.S. and Inventory Management (Fallout) and Siege Smash (Modern Horizons 3). There are 21 cards with the keyword and 3 more that grant it.<\/p>\n\n

How split second works: what you can still do<\/h2>\n\n

Split second doesn’t stop everything. Rule 702.61b says players may still “activate mana abilities and take special actions” while a split second spell is on the stack, and that triggered abilities “trigger and are put on the stack as normal.” Here is every case that comes up at the table.<\/p>\n\n\n\n

Casting an instant or a flash spell<\/td>No<\/td>3,754 Commander-legal instants and 607 nonland cards with flash are switched off, including all 286 cards that say "counter target spell".<\/td><\/tr>\n

You still get priority, you just can’t do much with it<\/h3>\n\n

A split second spell doesn’t skip priority. Each player still gets the chance to act before it resolves. The official rulings put it this way: players still get priority, “their options are just limited to mana abilities and certain special actions.” In practice that means everyone passes unless they have a mana ability or a face-down creature worth flipping.<\/p>\n\n

Mana abilities still work, and that includes sacrificing for mana<\/h3>\n\n

A mana ability is an ability that produces<\/em> mana (the rulings for Sudden Substitution stress it: “not an ability that costs mana”). Sol Ring, lands and Treasure tokens can all be used. The important part is sacrifice outlets that make mana. If an opponent casts a split second spell to steal or exile your creature, Ashnod’s Altar or Phyrexian Altar can still sacrifice it in response, because their abilities add mana. A Viscera Seer can’t: “Sacrifice a creature: Scry 1” is an activated ability that isn’t a mana ability. Of the 236 Commander-legal cards with an ability whose whole cost is “Sacrifice a creature:” or “Sacrifice another creature:”, only 7 are mana abilities.<\/p>\n\n

Turning a face-down creature face up is a special action<\/h3>\n\n

Turning a morph, megamorph or disguise creature face up doesn’t use the stack, so split second can’t stop it. The Trickbind rulings confirm it can’t counter “paying the morph cost to turn a face-down creature face up, since that action doesn’t use the stack.” If the creature has a “when turned face up” trigger, that trigger goes on the stack as normal. That is why the classic answer to a split second spell is Willbender: flip it face up and change the target of the spell. 111 Commander-legal morph, megamorph and disguise cards have a turned-face-up trigger, and 7 of them can counter, copy or redirect a spell.<\/p>\n\n

Triggered abilities trigger, but can’t let you cast anything<\/h3>\n\n

Split second doesn’t stop triggered abilities. Rhystic Study and Mystic Remora still trigger off a split second spell, and opponents can still pay for them. Death triggers, Chalice of the Void triggers and cast triggers all happen as normal. One exception: “If the resolution of a triggered ability involves casting a spell, that spell can’t be cast if a spell with split second is on the stack.” A cascade or discover trigger that resolves on top of a split second spell finds its card but can’t cast it.<\/p>\n\n

It doesn’t touch what is already on the stack<\/h3>\n\n

“Casting a spell with split second won’t affect spells and abilities that are already on the stack.” If an opponent has already cast a spell, your split second spell can’t stop it resolving. Split second protects the split second spell; it isn’t a counterspell. The order matters: if you cast Krosan Grip in response to an equip activation, the equip ability is already on the stack, so it stays there. The Grip resolves first and destroys the Equipment, and the equip ability then has nothing to attach.<\/p>\n\n

It doesn’t let you cast at instant speed<\/h3>\n\n

Split second isn’t flash. An Aura with split second such as In Too Deep or Take Possession can still be cast only in your main phase when the stack is empty. The In Too Deep rulings say it directly: split second “doesn’t allow players to cast the spell it’s on at times when they otherwise wouldn’t be able to cast it.”<\/p>\n\n

It is not “can’t be countered”<\/h3>\n\n

Split second stops responses, not counterspells as such. Nobody can cast Counterspell targeting a split second spell while it is on the stack, so in practice it can’t be countered by a spell. But a Willbender flip can change its target, a Stratus Dancer flip can counter it, and a triggered ability can still interact with it. Multiple instances of split second on one spell do nothing extra (rule 702.61c).<\/p>\n\n

Every split second card, ranked by Commander play<\/h2>\n\n

These are all 21 cards with the split second keyword, sorted by the number of Commander decks on EDHREC that run them. Krosan Grip is the clear number one at 207,995 decks: an artifact or enchantment answer that the owner can’t protect or activate in response (unless the activation is a mana ability). Legolas’s Quick Reflexes (113,581) is second, mostly as a one-mana protection spell that also untaps a creature.<\/p>\n\n\n\n

A few patterns stand out. Most split second cards are removal or protection that would normally get answered: destroying a combo artifact (Krosan Grip, Siege Smash), shutting off an army for a turn (Sudden Spoiling), or making sure you survive the turn (Angel’s Grace). Trickbind is the odd one: a split second Stifle that can counter an activated or triggered ability, including a fetch land’s activation or a storm trigger, without the opponent being able to respond with another copy. Sudden Spoiling is the best defensive card on the list: cast it during an opponent’s combat and every creature they control becomes a 0\/2 with no abilities, with no chance to pump or protect them in response.<\/p>\n\n

The three cards that give split second<\/h2>\n\n\n\n
Card<\/th>Set<\/th>Gives split second to<\/th>Condition<\/th>EDHREC decks<\/th>Cheapest printing<\/th><\/tr><\/thead>
Samut, Tyrant of Naktamun<\/strong><\/td>Reality Fracture<\/td>Every instant and sorcery spell you control<\/td>Always<\/td>16,229<\/td>$6.12 (FRA)<\/td><\/tr>\n

Samut, Tyrant of Naktamun<\/strong> is the one that changes what split second means in Commander. It is a 2\/1 Human Wizard for {1}{U} with one line of text: “Instant and sorcery spells you control have split second.” It is already in 344 decks as a commander on EDHREC two and a half weeks after release, and it is legal in Standard and Pioneer, where it is the only split second card in either format.<\/p>\n\n

Shadow the Hedgehog<\/strong> (Secret Lair x Sonic the Hedgehog) is the Rakdos version: each spell you cast has split second if mana from an artifact was spent to cast it, so Treasures, Sol Ring and Mind Stone turn it on. It covers creatures too, not only instants and sorceries. It leads 12,211 decks on EDHREC. Molten Disaster<\/strong> from Future Sight gets split second only when kicked, which makes it a board wipe that also damages every player and can’t be answered.<\/p>\n\n

What Samut actually turns off<\/h2>\n\n

The easiest way to see how strong Samut is: count what an opponent can’t do in response to one of your spells. We ran the searches on Scryfall against every Commander-legal card.<\/p>\n\n
