Agent Frank Horrigan card art
Agent Frank Horrigan lands as a massive, evasive threat that blankets your opponents' boards with -1/-1 counters just by attacking — the impact is immediate and punishing. The mana cost is steep, but blink effects like Deadeye Navigator turn every reentry into another counter-spreading trigger, and The Wise Mothman turns those counters into a radiation engine that draws cards and kills tables.

The Wise Mothman

The Wise Mothman

57.4% of decks · synergy 0.51

The Wise Mothman is the natural home — every -1/-1 counter Agent Frank Horrigan distributes triggers Mothman's radiation payoffs, accelerating the card-draw and creature-kill engine that makes the archetype tick.

02
Cleopatra, Exiled Pharaoh

Cleopatra, Exiled Pharaoh

45.0% of decks · synergy 0.43

Cleopatra, Exiled Pharaoh cares about counters and resource attrition, and Agent Frank Horrigan's attack triggers slot directly into that gameplan by softening opposing boards and feeding her counter-based value engine.

03
Jenova, Ancient Calamity

Jenova, Ancient Calamity

43.5% of decks · synergy 0.41

Jenova, Ancient Calamity scales off creatures entering and leaving, and Agent Frank Horrigan's size plus repeatable counter distribution gives Jenova both a credible beatdown threat and a way to shrink blockers that would otherwise survive her attacks.

04
Carth the Lion

Carth the Lion

38.9% of decks · synergy 0.37

Carth the Lion focuses on planeswalker loyalty manipulation, and Agent Frank Horrigan's aggressive pressure clears the small creatures that would otherwise chump-block or chip away at your walkers, protecting the superfriends gameplan.

05
The Master, Transcendent

The Master, Transcendent

30.6% of decks · synergy 0.24

The Master, Transcendent wants a wide threat base that pressures multiple opponents, and Agent Frank Horrigan's evasion and attack trigger spread counters across the table — exactly the kind of broad disruption a control-slanted Universes Beyond deck wants in its threat slot.

Commander is where Agent Frank Horrigan actually earns its slot — the multiplayer attack trigger hits every opponent simultaneously, so a single swing can distribute counters across three boards at once, which is a level of efficiency that simply doesn't exist in one-on-one formats. Legacy and Vintage are both legal on paper, but Agent Frank Horrigan is far too slow and narrow for either — those formats end before a seven-mana creature changes the game. Oathbreaker is the one non-Commander 60-card variant where it's legal, and a dedicated counters-matter signature spell could make it functional, though the competition for top threats is stiff there too.
