Ayara's Oathsworn

Creature — Human Knight

Menace
Whenever this creature deals combat damage to a player, if it has fewer than four +1/+1 counters on it, put a +1/+1 counter on it. Then if it has exactly four +1/+1 counters on it, search your library for a card, put it into your hand, then shuffle.

Ayara's Oathsworn card art
Ayara's Oathsworn enters as a 1/1 for two mana and grows to a 4/4 with menace at end of turn if a creature died this turn — a payoff that rewards the black staple of sacrifice and attrition without asking you to build around it. The cost is the reset: it shrinks back to 1/1 on your next upkeep, so unlike Nexus of Fate-style recursion engines or the board presence Sidar Jabari of Zhalfir generates, this card demands you either protect it or kill something every turn to keep it relevant.

Sidar Jabari of Zhalfir

Sidar Jabari of Zhalfir

31.4% of decks · synergy 0.29

Sidar Jabari of Zhalfir puts Ayara's Oathsworn into first strike combat repeatedly, and the Oathsworn's end-of-turn pump to a 4/4 with menace means it survives and dominates the blocks that would otherwise trade out weaker Knights — Jabari's first-strike granting ability turns the temporary power spike into a reliable two-hit clock.

02
Breena, the Demagogue

Breena, the Demagogue

29.9% of decks · synergy 0.29

Breena, the Demagogue rewards dealing combat damage to opponents, and Ayara's Oathsworn's menace keyword on its pumped turn makes it one of the harder creatures to chump — Breena, the Demagogue gets counters and draws the table's fire while the Oathsworn punches through whatever blockers remain.

03
Felix Five-Boots

Felix Five-Boots

14.1% of decks · synergy 0.14

Felix Five-Boots copies triggers from creatures that deal combat damage, so an Ayara's Oathsworn that connects while pumped generates doubled value on whatever death triggers or steal effects your deck runs alongside it — Felix Five-Boots turns every successful swing into compounding advantage.

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Ayara's Oathsworn is legal in Commander, Modern, Pioneer, Legacy, Vintage, and Oathbreaker, but its natural home is Commander, where sacrifice triggers and creature deaths happen every turn and the Oathsworn's conditional pump almost always fires. In Modern and Pioneer the two-mana 1/1 baseline is too fragile without a guarantee of the 4/4 state, and dedicated sacrifice decks in those formats have more consistent payoffs that don't reset each upkeep. Legacy and Vintage have the power density to make Ayara's Oathsworn irrelevant — those formats don't want a conditional beater at two mana when engines resolve on turn one.

Price Context

Current price

$0.51 bulk tier

At $0.51, Ayara's Oathsworn sits squarely in bulk territory, which is accurate — it's a role-player in specific Commander builds, not a staple that demands a premium. At this price there's no reason to hesitate if it fits your list, but don't expect it to climb; the conditional design keeps it out of the high-demand zone.
