Iona's Judgment

Five mana to exile one permanent reads steep until you notice what the targeting clause buys: this answers a creature or an enchantment with the same spell, and exile leaves no graveyard hook for recursion to grab. White had cheaper unconditional creature removal long before this, but most of it was destroy-based and left a body to reanimate; the rarer enchantment answers tended to be their own narrow cards. Folding both targets into one flexible removal spell, and doing it at exile rather than destruction, is the design idea here. The price is the flexibility tax: a Disenchant variant that can also hit creatures costs more than either job priced alone, and the sorcery speed means it cannot ambush in combat or respond to an activated ability on the stack. What you get for the premium is a removal slot that never sits dead. Against an aggressive board it kills a threat; against a problematic enchantment it plays as a hard answer that dodges the indestructible and regeneration tricks a destroy effect would trip on. It is the unglamorous workhorse end of white's removal suite: overcosted by any single metric, defensible because it refuses to be the wrong card in hand.
