Decklist: May 2026 BO1 Rakdos Sacrifice (Silver II --> Platinum IV) // Pioneer deck list mtg // Moxfield — MTG Deck Builder (Text list at bottom of post)

In May 2026, I played 75* games of Arena Best-of-One Pioneer with Rakdos Sacrifice and finished the month with a 53.3% win rate. Overall, the deck feels relatively solid and can compete against most of the format's top decks. However, Izzet Phoenix feels like an increasingly rough match-up (0% win rate in this data set) and I am not sure whether the lack of further progress I experienced after reaching Platinum IV was a product of my own gameplay, possible deckbuilding mistakes, or fundamental issues with the deck. Next month, I expect to play fewer games of Arena, and any analysis written afterwards will likely come out after the first week of July. However, given the relatively limited sample size of games that this month alone can provide, I am hoping that playing even half as many games in June can give me a slightly better understanding of this deck's match-ups and possible hard limits. I have been playing the list in the link on and off for a few years now, but last month's season was the first time I recorded information about match-ups.

*Technically 76, but one match ended with my opponent instantly conceding or disconnecting.

Notable Match-Ups (see bottom of post for full match-up list):

• Golgari Midrange => 4-3 (57.1% win rate): Golgari Midrange is a pretty even match-up overall. The match-up largely hinges on killing Unholy Annex payoffs like Sheoldred, the Apocalypse (a brutal card versus Rakdos Sacrifice in any match-up), the Ritual Chamber Demon token, and Mutavault before they snowball. It is unclear if all seven Golgari Midrange decks were running Badgermole Cub and Unholy Annex, but the overlap between the seven in card pool and playstyle appeared similar enough that I grouped them together anyways.
• Selesnya Ouroborid => 1-1 (50% win rate): This deck felt pretty similar in function to Golgari Midrange in terms of how I played against it (stopping snowballing before it starts). What remains unclear is how well Rakdos Sacrifice actually performs against this list on a consistent basis, given that I only played two games against confirmed Selesnya Ouroborid // Badgermole lists.
• Greasefang => 3-0 (100% win rate): I feel as if I got lucky in a small sample size of one game each versus Orzhov, Abzan, and Esper, as the Abzan Greasefang match-up felt like an unfavorable one in past seasons. It's also possible that the deck is slowing down in favor of consistency, which would give Rakdos Sacrifice more time to draw into an instant-speed removal spell and prevent a game-breaking Parhelion II turn. However, I don't know enough about Greasefang to confirm whether this is the case.
• Mono-Red Aggro => 6-3 (66.7% win rate): The Scamp versus non-Scamp (aggregate of several archetypes) win rates were wildly different, with four Mono-Red or Rx Scamp match-ups resulting in a 1-3 record (25% win rate) and five matches total versus Burn, Prowess, a Burn/Prowess hybrid list, Goblins, and a traditional RDW deck (ran Bonecrusher Giant, Burning-Tree Emissary, etc.) resulting in a 5-0 record (100% win rate). The small sample sizes for each sub-archetype appear to indicate that Scamp has the speed to consistently outrace Rakdos Sacrifice's set-ups, while lists like Burn and Mono-Red Prowess don't quite have the same speed. Mono-Red Aggro used to feel like a more even match-up, though, and it is possible that the non-Scamp matches were outliers. It is also worth noting that all five games against the non-Scamp decks were before the Cori-Steel Cutter ban.
• Azorius Control => 2-3 (40% win rate): Azorius Control is not an unbeatable deck, but the combination of excellent card filtering and abundant cheap interaction makes it difficult to either outrace or outlast it. This is further compounded by how win cons like Teferi, Hero of Dominaria and The Wandering Emperor can be played in a way that limits the window for interaction. Teferi's +1 opens up mana for counterspells, while The Wandering Emperor can be flashed in after you have tapped out for the turn. Rakdos Sacrifice can outrace the deck on some occasions and on others outgrind it with Tenacious Underdog or the right synergy packages, but this match-up is difficult enough that I wouldn't be surprised to see worse win rates here in future months.
• Izzet Phoenix => 0-4 (0% win rate): At 0-2 pre-Cutter ban and 0-2 post-Cutter ban, Izzet Phoenix remains a consistently difficult match-up. The deck puts up a fast, evasive clock that is hard to race or shut down, and the deck's numerous cantrips and removal pieces simultaneously act as enablers for this clock. I've done better than I did last month versus Phoenix in the past, but even then the match-up still felt relatively difficult. I expect that I will continue to struggle this month, as I am not experimenting with designated anti-Phoenix tech yet and don't see how any of the changes I plan on making will improve the match-up. If I want to keep playing Rakdos Sacrifice, this match-up might just be an L that I have to take.
• Additional Notes:
  • I had a 2-4 record (33% win rate) versus Izzet Prowess, but did not see the deck once in the 16 games I played post-Cutter ban.
  • Mono-Green Devotion (1-3 record => 25% win rate) was among the decks that I faced more frequently, but MTG Goldfish data suggests that it doesn't make up a significant portion of the overall meta.
  • I played three games against Four & Five Color Midrange decks (1-2 record => 33% win rate), but did not write down if any of them were Niv to Light decks.

Changes for June 2026: Upon actually opening the deck list for the first time in months, I was surprised to find that a lot of the cards that I was considering cutting were not as prevalent as I assumed. As such, cuts and modifications ended up being relatively lean going into June. Of the seven spells that I chose to take out, six of them were spells that are frequently dead draws if you are already behind. Village Rites, a consistently dead card, was the easiest cut. The three copies of Eaten Alive gave me countless clutch moments, but they are also pieces of sorcery speed interaction that require either a creature to sacrifice or five mana to spend. The ceiling is high for the card, but more often than not I found myself closer to its low floor. Deadly Dispute is a similarly high-variance card, and I cut down to two copies. March of Wretched Sorrow is the 7th spell that I cut. While it is less synergy-dependent than the other cards, it can still be pretty hit-or-miss depending on whether you have the mana and/or black cards in hand to spare.

A massive part of why four out of these several spells were removal is because I want to experiment with Bitter Triumph, a card that provides instant-speed unconditional Planeswalker and Creature removal. It doesn't exile the removed permanent or provide synergy upside like Eaten Alive, and it pings you instead of healing you like March would. However, it has a far higher floor and is far less dependent on specific situations. The remaining five spell additions were four copies of Scavenger's Talent, a flexible Food token engine that can provide filtering and late game staying power, and a 4th copy of Cauldron Familiar to synergize with this new source of Food tokens. Meanwhile, I replaced my singleton copies of Haunted Ridge and Dragonskull Summit with two copies of Blackcleave Cliffs, sacrificing late-game consistency for early-game consistency. Playing around the requirements of Ridge and Summit can sometimes be a hassle during the first two turns, and I want to be able to deploy early-game setup pieces more efficiently.

Thank you for taking the time to read this and see you (maybe) in July. If you have further questions, let me know and I will do my best to answer them.
