Artificer's Intuition, a blue MTG card that was printed just once, twenty years ago, has suddenly jumped up in price, rising from $4.10 on Friday to $11.30 today, according to the market tracker at MTG Goldfish
The difference is that while they have an ink cost on them, there is also an extra block of text in the description area of the card which details that you can exert a character (turning them sideways and opening them to attack) of a minimum cost in order to play the song card for free
