Baleful Eidolon staples deathtouch onto any creature you enchant, turning even a 1/1 into a blocker that trades with anything. Two mana to cast and one black to bestow makes it one of the cheapest ways to distribute deathtouch in the format.

Baleful Eidolon finds its best home in Commander, specifically in Voltron and enchantress strategies that want to stack auras — bestow means it's never a dead card, since it enters as a creature if you have nothing better to enchant. In Pauper it sees occasional play in black enchantment synergy shells where the common-legal deathtouch is genuinely hard to replace at this cost. Legacy, Modern, and Pioneer have enough efficient threats and interaction that a two-mana deathtouch aura rarely competes, so it stays on the bench in those formats.

Price Context
Current price
$0.04 bulk tier
At $0.04, Baleful Eidolon is pure bulk — you're buying it out of a commons box, not a singles listing. That price is effectively a floor; it won't drop further, and the card's narrow role means no spike is coming.
