Ghostfire Slice deals damage equal to a spell's power to any target — on an instant for two mana, that's a removal spell and a burn spell stapled together whenever you're casting anything with a power stat. Imodane, the Pyrohammer copies it to every opponent simultaneously, turning a two-mana instant into a three-way execution at no extra cost.
Best Commanders
Commanders with the highest synergy
Imodane, the Pyrohammer
Imodane, the Pyrohammer's triggered ability copies instants and sorceries that deal damage to a single target and redirects that damage to each opponent, so Ghostfire Slice stops being spot removal and becomes a three-player lightning bolt the moment Imodane is on board.
Aegar, the Freezing Flame
Aegar, the Freezing Flame draws a card whenever a Giant, Wizard, or spell you control deals excess damage to a creature or planeswalker, and Ghostfire Slice routinely overkills smaller creatures with a high-power spell — turning removal into card advantage in the same transaction.
Niv-Mizzet, Visionary
Niv-Mizzet, Visionary triggers off instants and sorceries, and Ghostfire Slice is both — cheap enough to chain and interactive enough to matter, slotting cleanly into the spell-dense shell Niv-Mizzet, Visionary rewards.
Tor Wauki the Younger
Tor Wauki the Younger pings for two damage whenever you cast an instant or sorcery, so Ghostfire Slice layers two damage sources on a single cast: the Slice itself and the commander's trigger, making each removal spell punch above its mana cost.
Ashling, Flame Dancer
Ashling, Flame Dancer creates spell-doubled tokens off noncreature spells, and Ghostfire Slice qualifies — meaning each cast can generate a hasty creature while also eliminating a threat, giving Ashling, Flame Dancer both board presence and interaction from one card.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Ghostfire Slice is legal in Commander, Legacy, Modern, Vintage, and Oathbreaker, but it's almost exclusively a Commander card — the power-matters clause is too parasitic for linear Modern or Legacy shells, where unconditional removal like Fatal Push or Prismatic Ending does the job without requiring a high-power spell in hand. In Commander it earns its slot specifically in spell-slinging decks where the spells you're casting already have power stats, turning a situational rider into a reliable damage engine. Oathbreaker can use it for the same reason Commander does, just in a smaller pod with a faster clock.

Price Context
Current price
$0.36 bulk tier
At $0.36, Ghostfire Slice is firmly bulk — a pickup that costs less than a sleeve. Bulk rares with narrow commander-specific synergy rarely climb unless the commander breaks into the mainstream, so treat it as a cheap role-player rather than a spec target.
