Our next round of Regional Championships is here, and many players are beginning to turn their attention to the events. After all, Murders at Karlov Manor just recently released, so this is a perfect time to see what new cards shine early on in Modern in a competitive setting. Recently, we covered the value of the Surveil Lands to various archetypes, such as Temur

decks, as well as a unique upgrade for Domain Zoo decks in the form of

.
As we wait to see what other potential breakout cards and decks make their presences felt at these Regional Championships, though, it’s important not to forget about other formats. As strong as some Karlov Manor cards may feel in Modern, the immense impact the set is already having in Pioneer is undeniable. The new cards have only been available on Magic Online since February 6, and we’re quickly beginning to see some cards help elevate certain strategies.
Today, we are going to focus on one deck in particular that got a plethora of new tools to try out. This deck makes amazing use of two new additions to Pioneer that have helped further solidify its spot as a strong choice in the metagame. Furthermore, as a

Obviously, Bring to Light is a great card to reveal with Niv-Mizzet. Beyond that, many usual suspects like

One of the main issues that these Niv-Mizzet decks have had in the past, even with these excellent ways to pull ahead in the mid to late game, is staving off initial pressure. Sure,

Karlov Manor gave this deck a massive edge in this area. The impact of Lightning Helix cannot be understated. It helps remove pesky attackers just like

The other massive upgrade from Karlov Manor is

Unique Tutor Targets

Moving past Helix and No More Lies, this archetype also got a nice boost with some strong cards to tutor for with Bring to Light. First up, we have Urgent Necropsy. Urgent Necropsy is a bit tough to cast, because you need a stocked graveyard and multiple good targets to make casting this card worth it. That being said, it can definitely swing things in your favor in the right circumstance.
Against other Yorion decks, for instance, getting to destroy a big Creature and Leyline Binding can be a big swing. Getting to remove

, simply helping you stabilize the board. The added upside of getting to remove all copies of a specific card from your opponent’s graveyard, hand, and library, though, comes in handy in a number of matchups.
One of the biggest matchups, of course, is Abzan

Whenever you gain life, Amalia Benavides Aguirre explores. Then destroy all other creatures if its power is exactly 20. (To have this creature explore, reveal the top card of your library.

can undo a lot of your work.
Even if you stabilize initially, your opponent may be able to set up the Amalia and Wildgrowth Walker combo soon after, undoing all of your progress. With Deadly Cover-Up, you can wipe the board and potentially exile all copies of Amalia from your opponent’s deck. Given how popular Abzan Amalia is, this single extra card is a much bigger upgrade than may seem at first glance.

Strengths and Weaknesses

Overall, Murders at Karlov Manor provided enormous improvements to the Niv to Light archetype. Lightning Helix is a game-changer against aggressive decks, while a handful of new one-ofs like Deadly Cover-Up give the deck additional angles of play in specific situations. Even so, this deck is not fool proof.
Perhaps the biggest weakness this deck has is that it is rather slow and mana intensive. This can make it a bit vulnerable to decks with good mixes of disruption and pressure, such as Azorius Spirits. Decks like Lotus Field combo can be problematic too. You have a naturally slow clock and not a ton of disruption. Even Azorius Control can be a bit tough. Outside of Up the Beanstalk, most of your value-oriented cards in the matchup are a bit clunky and can easily get countered as a result.
Luckily, both Dovin’s Veto and Soul Search play vital roles out of the sideboard in these matchups. Add No More Lies into the equation, and you’ve got a recipe for success even in some of your historically hard matchups. If you’re going to play Pioneer in the coming weeks, you should certainly make it a point of emphasis to have a decent gameplan against this deck.
