Night of Souls' Betrayal card art
Night of Souls' Betrayal kills every 1-toughness creature on the board the moment it resolves — tokens, mana dorks, utility creatures — and keeps killing them for as long as it stays in play. The four-mana cost is real, but Maha, Its Feathers Night turns that cost into a feature: the enchantment itself feeds Maha's power-scaling ability, making Night of Souls' Betrayal both a sweeper and a buff in that deck.

Maha, Its Feathers Night

Maha, Its Feathers Night

74.1% of decks · synergy 0.72

Maha, Its Feathers Night cares about the highest mana value among permanents you control, and Night of Souls' Betrayal at four mana contributes directly to that count while simultaneously clearing the board of any 1-toughness blockers standing between Maha and a lethal attack.

02
Grismold, the Dreadsower

Grismold, the Dreadsower

31.8% of decks · synergy 0.32

Grismold, the Dreadsower hands Plant tokens to opponents, and Night of Souls' Betrayal turns every one of those gifts into an immediate death trigger — each token dies the instant it enters, converting Grismold's forced generosity into a one-sided engine that pumps Grismold and draws cards without ever letting opponents benefit.

03
Massacre Girl, Known Killer

Massacre Girl, Known Killer

28.5% of decks · synergy 0.26

Massacre Girl, Known Killer triggers on each creature that dies with a -1/-1 counter on it, and Night of Souls' Betrayal ensures every 1-toughness creature entering the battlefield dies immediately — generating a continuous stream of death triggers whenever opponents play or token-generate into the effect.

pauper not legal
oathbreaker legal

Commander is where Night of Souls' Betrayal does its best work: multiplayer boards are littered with mana dorks, spirit tokens, and utility creatures with exactly 1 toughness, and a static enchantment that permanently invalidates that entire category of creature is a meaningful threat. In Legacy and Vintage, the card is legal but rarely played — those formats move too fast for a four-mana enchantment that doesn't immediately end the game, and dedicated hate pieces for small creatures are cheaper and more efficient. Night of Souls' Betrayal is unavailable in Pioneer, Standard, and Pauper, so Commander and Oathbreaker are the practical homes, with Commander by far the format where it earns its slot most often.

Price Context

Current price

$2.56 cheap tier

At $2.56, Night of Souls' Betrayal sits firmly in the budget-staple tier — cheap enough to slot into any Commander deck that wants it without a second thought. The price has stayed low because the card's niche is narrow: it's powerful in the right shell and nearly unplayable outside it, which keeps demand stable rather than speculative.
