Funeral Charm

The instant-speed modal spell built before modal spells were a settled idea: a one-mana black charm whose three options have almost nothing to do with each other except that you would never want all three at once. The discard line is mono-black hand attack on the stack, the kind you hold up to strip a key card during the opponent's draw step rather than spend on your own turn. The +2/-1 line is split between combat trick and removal: it kills a one-toughness creature outright, or pushes through a surprise two extra damage. The swampwalk line is the dustiest of the three, an evasion grant that only matters against an opponent who happens to keep a Swamp in play, which is exactly the sort of flavor-first option the early charm cycles loved to bury at the bottom of a card. What makes the design hold up is the instant speed under all of it: every line gets to ambush a window the opponent thinks is safe. The discard answers their plan after they have committed to it, the +2/-1 turns a profitable block into a dead creature, and even the swampwalk can steal a swing nobody saw coming. The Mirage-block charm cycle (one per color) was the template Wizards has returned to many times since, and this is the black entry: cheap, flexible, and content to do a small thing at exactly the right moment.
