Strixhaven’s New Pox Variant Enables Turn-5 Insta-Win

Secrets of Strixhaven keeps coughing up weird combo pieces. We covered last week how cards from the newest MGT set enable infinitely large dragons (and can burn down the whole table with a little help), or how the new Paradigm mechanic allows some hilarious (for you…) wins with Phage the Untouchable.

Pox Plague might be one of the nastiest yet. On its face, it is a symmetrical black sorcery: everybody (including the caster!) loses half their life, discards half the cards in their hand, and sacrifices half the permanents they control, rounding down each time.

The Bloodletter of Aclazotz + Pox Plague Combo

This combo is pretty simple. Resolve Bloodletter of Aclazotz, then cast Pox Plague on your turn…

… and that's about it!

 Pox Plague makes each player lose half their life, rounded down. Bloodletter of Aclazotz says that if an opponent would lose life during your turn, they lose twice that much life instead. That means opponents on even life totals die outright.

The pesky quirk here is that opponents on odd life totals survive at 1.

If an opponent is at 40 (or 20, or 12, or any other even number), Pox Plague makes them lose 20 (or 10, or 6), and Bloodletter of Aclazotz doubles that to exactly their life total. Blam. They're dead on the spot.

But they are at 39 (or 19, or an odd number), Pox Plague makes them lose 19, since it rounds down from 19.50 (or makes them lose 9 since it rounds down from 9.5, etc). And Bloodletter of Aclazotz doubles that to 38, leaving them at 1.

So yes, the Bloodletter of Aclazotz + Pox Plague can absolutely wipe out all of the table and let you win on the spot, but it is not a guaranteed two-card kill.

What Are Pox Effects?

In Magic lingo, “Pox effects” are named after the original Pox, one of black’s classic spells.

Pox makes each player lose 1/3 of their life, discard 1/3 of their hand, and sacrifice a 1/3 of their creatures and lands. There's also Smallpox, with a much small effect, and now Pox Plague (which WotC should really have called “Large Pox”!).  

The quirk, as we saw above, is that while Pox Plague is clearly cut from the same cloth, the original Pox rounds up, while Pox Plague rounds down.

There's also the difference that Pox makes players sacrifice creatures and lands separately, while Pox Plague instead makes them sacrifice permanents of their choice.

The Wound Reflection + Pox Plague Combo

There is also a very similar version of this combo with Wound Reflection.

Instead of doubling the life loss immediately like Bloodletter of Aclazotz, Wound Reflection waits until the end step and makes each opponent lose life equal to the life they lost that turn. The math is the same: even life totals die, odd life totals survive at 1. So if your deck already likes one effect, it may easily want the other too.

Which Commanders May Want This?

You do not need to build around Pox Plague] from scratch, but a few mono-black commanders slot this kind of effect more easily than others. [card]K'rrik, Son of Yawgmoth is an obvious example. He is a popular mono-black commander, strong enough to see a lot of cEDH play, and Bloodletter of Aclazotz even shows up in a couple of cEDH K’rrik decks.

Sheoldred, the Apocalypse is another good home. She is a very popular mono-black commander, Bloodletter of Aclazotz already appears in Sheoldred builds, and the deck naturally leans toward punishing life totals and making opponents miserable for trying to play normal Magic.

Pox Plague plus Bloodletter of Aclazotz is definitely not a polished, competitive combo. It is too expensive, too symmetrical, and too dependent on life-total math for that. But it is still a very real two-card interaction that can kill the whole table, and even when it fails at outright killing players, it can massively change the combat math: Attacking a 39-life opponent is very different from attacking a 1-life opponent!
