Inner Demon staples +2/+2 and flying onto a creature permanently — and if that creature is already enchanted, it also hands you a free Aura from the top eight cards of your library. Six mana is the honest cost of that package, but Killian, Ink Duelist cuts it to four, which is where the card stops being fair.

Killian, Ink Duelist
Killian, Ink Duelist reduces Inner Demon to four mana and already wants a critical mass of Auras to trigger his lifelink-and-menace engine, so Inner Demon does double duty: it grows the threat and digs for the next Aura in the chain.

Inner Demon is a Commander card front to back — the free Aura trigger is most explosive when you're running a dedicated enchantress or Voltron pile with a full suite of enchantments to cascade into. In Legacy and Vintage it's technically legal but six mana for an Aura is never competing with those formats' actual threats. Oathbreaker is the one fringe home where a focused 60-card Aura shell could make the cascade trigger fire consistently, though the format's smaller card pool limits the ceiling.

Price Context
Current price
$0.24 bulk tier
At $0.24, Inner Demon is bulk — easy to pick up as a throw-in or cheap addition to any Aura build. Bulk rares with narrow applications tend to stay cheap, so don't expect price movement unless a pushed Aura commander spikes demand.
