Here's a series of cards that synergize with each other, but require a bit of luck. They have an effect which doesn't work all of the times, and depends on luck or "connection with the opponent", but they're made so they always do something; also they can search another card if everything works perfectly (spoiler alert: really unlikely to happen.)
They use weird OCG and the "Declare a card type" mechanic, so there will be many mistakes.
Used by Ibuki Uranai in the fanfiction.
