Since I'm not capable of art and so most things regarding Photoshop, I write my thoughts instead:
"Negasphere 6 Entropy (5 upped)
Permanent
Removes Immortality from every creature on the field. Grants Immortality to random creatures, based on the value of removed abilities divided by 2, rounded down at the end of each of your turns."
So, this texts fits in the box at a font size of 9. If one would explain to me how to scaling down the gap between the lines on the card in Photoshop, I would like to see a "Sacrifice this card, if no creatures are immortal after your turn."
