Rulings
- You can target a Limited monster with "Next to be Lost", but you don’t search or shuffle your Deck. Essentially, there is no effect.
- You cannot target a Token Monster with "Next to be Lost" because they cannot exist in your Deck.
- If the target of "Next to be Lost" is flipped face-down in a chain, the effect of "Next to be Lost" disappears because you can no longer check the Monster Card’s name.
- If the target of "Next to be Lost" is destroyed in a chain, the effect of "Next to be Lost" disappears.
- If you target "Proto-Cyber Dragon" on your side of the field for "Next to be Lost", you send a "Cyber Dragon" from your Deck to the GY, not a "Proto-Cyber Dragon".
- You can target Embodiment of Apophis with Next to be Lost, and a copy of Embodiment of Apophis will be sent from your Deck to your GY.
