Twincast Copying Memory lapse

Oppenent cast twincast copying my memory lapse targeting my memory lapse. This caused an infinite loop of the game trying to put my memory lapse into the correct deck position.

Reproduce the interaction where Twincast copies Memory Lapse while targeting Memory Lapse, and trace the game’s handling of the spell’s deck-positioning effect. Identify why the resolution loops, then verify that the copied spell resolves without repeatedly attempting to place the card in the deck.
