Obliterate. Cabal Pit. Tombfire. The introduction of the Wishes from Judgment into the Standard environment has allowed many previously-shunned "niche" cards to finally earn slots in players' sideboards. And some of the stories that have come from these cards have players slapping their foreheads in disbelief.
Chris Benafel, playing the Mini-Colony's "Red Zone 2K2" deck, used Living Wish to fetch Intrepid Hero against his round 3 opponent. The Hero, a white 1/1 that never saw play back when it was legal in the Urza block, taps to destroy a creature with a power of 4 or greater, making it a great weapon against blue/green Roar of the Wurm decks.
Ed Fear has a horror story involving Burning Wish. In round two, Ed's opponent (Yuuki Murakami) Burning Wished for Reprocess, cast it, defended it with a Counterspell, and then sacrificed all of his permanents except his Psychatog, drawing a huge number of cards. All the fresh cards plus the full graveyard allowed him to kill Fear with one 'Tog hit when Fear figured he was safe.
Andrew Wolf has been telling a story of his match against Scotland's Douglas Penman in which both players were packing Cunning Wish. Penman had earlier wished for an Opportunity, but hadn't had a chance to cast it. Wolf had also wished, but for a Mana Short to try and force an Upheaval through. At one point, Wolf cast a Fact Fiction. Penman tried a Circular Logic, but Wolf had a Logic of his own. Penman, out of counter, announced Opportunity, hoping to draw more permission. But Wolf had other ideas. He responded with the Mana Short, tapping Penman out, and then Wolf wished... for a Divert. "Thank you, but I'll be drawing four cards, not you." On top of that, his Fact or Fiction resolved, and winning the game was just a formality.
