- Art is not correctly used under the Licence offered by "Creative Commons"
What do you mean? It allows me to distribute the art, and it allows me to adapt it. I don't see anywhere that it doesn't allow me to do whatever I did.
- What interaction is to occur if your field is full?
Read the additional informations. If your field is full, then the creature is instantly killed if it belongs to your opponent. If it belongs to you, then its ability is changed to Darkness.
Think of it like this. It kills the target creature, then it creates a copy of the creature on your field. If your field is full, then the dark copy will not appear on your field, but the original creature is still killed.
- For technical reasons replace the last reference to Darkness with :Darkness
But that implies the cost is ONE Darkness quantum, which is not always true.
- Conversion is an ok name but something more specific maybe better. The theme of the name is ok, but once you use conversion it cannot be used for anything else. An option might be "Defection" or "Renounce Faith"
For all I care, the upped name could also be Corruption, or Improved Corruption, or whatever. It's not important.
