Blurry Visionary

The joke is physical and it commits all the way: staple two of your own cards back-to-back into a single sleeve and treat the pair as a modal double-faced card for the rest of the game. Every MDFC ever printed arrives with a fixed front and back decided by the designer; this one hands that decision to you, lets you point either of two unrelated cards outward, and then puts that fused card into your hand where you play whichever side the moment calls for. The absurd cases assemble themselves: two lands become a fixer that answers to either color, two finishers become a spell whose mode waits until you have seen the board, a narrow answer sleeved behind a creature becomes a card that is never dead in the wrong game. It belongs to the small tradition of designs that reach past the rules text to manipulate the physical objects on the table (the roll-a-die cards, the assemble-a-contraption cards, the ante-adjacent oddities), where the ritual is inseparable from the payoff. The reset clause is the honest bookkeeping at the end of the bit: you altered the physical composition of two cards mid-game, and the card politely asks you to unfuse them when the game is done. Note too that the effect does not care what the top two cards are, only that they can be sleeved together, which is what turns a 3/2 body into a mechanism for smuggling two cards into your hand under one selection.
