Does the Vision keyword stack, and if so, how does it work?

Ruling: If something has multiple instances of Vision, they trigger separately.

Sequence:

• First Vision triggers: look at 1 card, choose to keep on top or put on bottom
• Second Vision triggers: look at 1 card, choose to keep on top or put on bottom
• Third Vision triggers: look at 1 card, choose to keep on top or put on bottom
• (Continue for each instance)

Nuances:

• If you choose to keep a card on top during the first Vision, you can forgo looking at the remaining Visions since you already know what card you want on top
