When playing Promising Future while Brynhir's effect prevents the opponent from playing cards, what happens to the card chosen by Promising Future?

Ruling: This follows the "Do As Much As You Can" principle. The opponent chooses a card from Promising Future and it remains banished, since they cannot play it due to Brynhir's effect.

Sequence:

• Resolve Promising Future normally
• Opponent chooses a card to banish
• The card remains banished (the step where opponent would play the card is skipped)
• The card does not go to trash

Nuances:

• Brynhir does not override Promising Future; both effects apply
• All steps of Promising Future resolve except the opponent playing the banished card
