Spontaneous Combustion kills a creature and deals damage equal to its toughness to each other creature — a board wipe and a removal spell rolled into one at three mana. It's a Commander staple waiting to happen in the right shell, and criminally underplayed everywhere else.

Spontaneous Combustion is legal in Commander, Legacy, Vintage, and Oathbreaker — and realistically, Commander is the only place it sees meaningful play. Legacy and Vintage have access to strictly more efficient removal suites, so Spontaneous Combustion doesn't compete there. In Commander, the ability to chain a targeted kill into a sweeper effect on a single card is exactly the kind of two-for-one that three-mana slots should be doing, especially in Grixis or Jund builds that want density over redundancy.

Price Context
Current price
$0.21 bulk tier
At $0.21, Spontaneous Combustion sits firmly in bulk territory — you're picking this out of a $0.25 bin, not budgeting around it. Bulk rares with niche Commander appeal rarely climb unless a high-profile deck puts them on the map, so treat it as a cheap include, not a hold.
