Premodern: Mono Red Sligh - Deck Tech & Sideboard Guide

Mono Red Sligh is one of the most accessible strategies in Premodern and, consequently, one of the most popular in the format. Its name originally comes from player Paul Sligh, who, in a 1996 Pro Tour Qualifier, presented a red list aimed at maximizing mana efficiency with cheap creatures and spells—the deck concept was conceived by Jay Schneider, but Paul was the one who reached second place in the event.

However, the archetype we call Sligh in Premodern would have another name in any other format: Burn—its natural evolution in the hands of Seth Burn, a New York deckbuilder who, in 2000, presented a variant that focused more on damage spells and less on board presence. His version would take Alex Shvartsman to second place at that year's Grand Prix Seattle.

The list above was used by player medvedev in a Premodern Challenge, where he won the event with a 9-0 record. Unlike other Sligh variants, this deck is entirely focused on short-term damage spells: out go pieces like Cursed Scroll and in come Flame Rifts, whose damage scope is the highest in the format alongside Fireblast.

The Sideboard also stands out for its focus: this deck wants to beat Stiflenought and doesn't care as much about interacting with certain strategies, as it can race them without needing to worry too much about using specific hate cards, following the philosophy that too many side-ins reduce consistency in closing out games, proposing that the Sligh philosophy is purely to end the match in the fewest possible turns.

Maindeck

Jackal Pup is the symbol of Sligh: low cost, efficient body, and constant pressure in a single creature. It obviously loses usefulness as the game goes on, but like almost all cards in the list, it wasn't included with the late-game in mind.

Mogg Fanatic offers early-game pressure, extra reach when it can no longer attack, and the essential ability to deal with X/1 creatures—notably cards like Wellwisher and Priest of Titania in Elves, which tend to be passports to defeat if they stay on the board.

Ball Lightning represents six damage for three mana, often forcing the opponent to choose between losing creatures or taking damage that will accumulate with other spells the following turn. Turns where we sequence it with Fireblast after combat tend to be our "finisher."

Grim Lavamancer converts everything we use during the match into a recurring damage source. It's the only non-land card designed for longer games, allowing us to keep pressuring even after the opponent stabilizes the board. It's also essential for holding off Aggro decks with a more explosive clock.

The Burn.

Lightning Bolt needs no introduction. Three damage, one mana, instant speed: everything we want in a card—it deals with creatures if needed, pressures the opponent early, and can close out games alongside other spells.

Seal of Fire allows investing mana on one turn to use its damage effect later. It's relevant in games where we need to consider our spells as board interaction instead of direct damage, while not losing that function in Control and Combo games.

Incinerate complements Lightning Bolt and Seal of Fire in the flexible damage package. Despite costing one more mana, the average damage-to-cost ratio is still acceptable and effective for Sligh.

Flame Rift is our most aggressive bet. With the Metagame moving away from the mirror—at least in Challenges—it's possible to move away from cards like Cursed Scroll and bet on a more explosive potential against Control and non-interactive matchups, and this card's average damage is considerably high for the format's standard.

Fireblast functions as a finisher in most cases at the lowest possible cost. We usually don't have problems sacrificing two Mountains as the game goes on, and we can also use them as fuel for Grim Lavamancer or Barbarian Ring to reach six damage in a turn.

Sulfuric Vortex guarantees recurring damage every turn while preventing life gain, nullifying one of the best ways to beat Burn in the format. Essential against Midrange and Control to ensure reach even without extra resources.

The Fetch Lands help fuel the graveyard to trigger Barbarian Ring more easily, providing a land that also functions to damage the opponent in longer games. Grim Lavamancer also benefits from them to control the board or pull the reach of our deck.

Sideboard

In this list, most of the Sideboard seems to have a clear target: Stiflenought. Mogg Salvage and Overload work very well in this matchup, and Salvage has the bonus of being cast for free.

Pyroblast is direct interaction against blue decks like Landstill and Replenish while also functioning as a pinpoint answer against Stifle, Vision Charm, or Counterspell.

Price of Progress punishes greedy mana bases and archetypes using more than two colors. It's common for it to deal four or more damage for two mana in these games, making it our most effective spell as the game progresses.

Tormod's Crypt deals with graveyard-based strategies without compromising our mana investment. Essential against Oath, Reanimator, and Replenish.

Stiflenought

IN

OUT

Stiflenought is extremely efficient with its mana, so we need to cut cards that cost too much and open too many windows for generating positive Tempo with Hydroblast or Foil / Daze.

Sligh

IN

OUT

Flame Rift is an extremely risky card in this matchup, but Jackal Pup offers too many positive trades for the opponent. It's likely our opponent uses Cursed Scroll to extend their clock, so we add Overload.

This deck variant is poorly positioned in the mirror if we aren't on the play.

Azorius Landstill

IN

OUT

Landstill easily answers Ball Lightning with Mana Leak and Swords to Plowshares, and our mana efficiency and ability to pressure must be greater than the opponent's ability to defend and stabilize. Price of Progress plays an essential role in this matchup, given the high number of utility lands in the opponent's list.

Replenish

IN

OUT

This is a race matchup: you need to win before the opponent assembles the combo. Pyroblast helps delay Parallax Tide while also answering Hydroblast on a key spell.

Gruul Oath

IN

OUT

Overload is the best tool in this matchup, as we need to deal with Sphere of Resistance and Zuran Orb if we want to win this game, while Tormod's Crypt functions as removal against Terravore.

Despite our mana efficiency, we can't count on the opponent's LD not disrupting our ability to cast our more expensive cards, so we remove Ball Lightning and Sulfuric Vortex.

Hermit Reanimator

IN

OUT

As with other combos, our plan involves winning before the opponent uses Hermit Druid. Our creatures tend to trade poorly or be blocked easily, so we need to focus on the reach of damage spells.

Psychatog

IN

OUT

Psychatog is a Control matchup where our main focus is to prevent the game from going long. We rely on permanent power on the board to force the opponent's interactions while our Burn spells pressure, but a very aggressive hand from them with Duress and Hydroblast can disrupt our game plan long enough for them to stabilize.

That's all for today!
