Radiant Purge

Exile-based removal that asks one question of its target: are you more than one color? The narrow gate is the entire transaction. Point it at a mono-colored board and it does nothing, but the payoff for the restriction is total: exile sidesteps regeneration, dodges death triggers, ignores indestructible, and answers an enchantment as cleanly as a creature, all for two mana at instant speed. That last clause is the underrated half of the design. Most cheap white removal of this era could only point at creatures, so a two-mana white instant that also exiles a multicolored enchantment widens the answer set without widening the color requirement, which is how the card pays for its rate. The multicolored qualifier is a deliberate metagame lever rather than a flavor accident: it rewards a format full of gold cards and punishes a format full of mono-colored ones, which means the card's value floats with the table rather than sitting at a fixed level. The bargain here is the same one conditional white exile has always struck, trading universality for a steep rate: Path to Exile hands the opponent a land, Journey to Nowhere leaves an enchantment behind to be destroyed, and this pays its toll up front in the targeting clause. That is why it lands as either the cleanest answer in the deck or a slot held in reserve until the right opponent sits down.
