From AMLopedia
do you pay one? was a question often asked by Adam during Magic: The Gathering games.
The phrase revolved around a card that Adam owned called Rhystic Study. The text read:
- Whenever an opponent plays a spell, you may draw a card unless that player pays 1.
This meant that every time Liam or Marcus played a spell (usually about once a minute), Adam would say "Do you pay one to do that?" Adam had 4 of these cards in his deck at one point, leading to an excessive usage of this phrase.
