In some card texts you will come across a sentence such as
"all monsters/cards" or "both monsters/cards"
or
"return/send/banish/etc. them/those/etc."
Well text makes the difference on whether you need all targets on the field/graveyard/or hand or you can add any you can get.
If a text has either "All" or "Both" in its text, you need both targets available, otherwise when one of the targets needed for the effect is gone, the entire effect disappears.
If the text does not contain either, then the leftover monsters for the effect will be used.
