Vision

Vision is a Triggered Ability keyword present on Permanents.

It is functionally short for "When this is played, look at the top card of your Main Deck. You may recycle it."

Multiple instances of Vision trigger separately, and the player may choose to recycle or not recycle for each instance separately.

If the player does not recycle the top card and nothing else happens in between the triggers resolving, each instance of Vision will see the same card.

Vision, and whether or not a permanent has Vision, is a characteristic of the permanent and may be checked or referenced by other Game Effects.
