Look up Unruh Effect for a
interaction.
An accelerated body in a vacuum percieves radiation as if emited by a heated body.
Maybe you can make a connection between radiation and quanta. The card could be
![Entropy :entropy](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/entropy18x18.png)
and consume
![Gravity :gravity](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/gravity18x18.png)
(causing an acceleration) to make something with your quanta (since the radiation is thermal, scrambling your quanta, which could be a quanta fixing for a rainbow deck, seems good thematicaly).
