I was playing on Cockatrice when I made a random broken card that gave a +1/+1 counter on itself everytime you added mana to your mana pool. Someone responded and one thing led to another and we tried to fix it. Then we thought how can we do this with other colors. In the end it resulted in us creating these guys.
