Idea: I think I am the first to come up with this idea, but i am not sure.
Element: Starts out being Time or Aether. Kind of pulling toward Aether.
Type: Creature
Name: Shape Shifter : (i dont know about the upgraded name)
Concept: The card is played and it is automatically Immaterial/Immortal. Then every turn the creature changes into a new creature. Any element, can be rares and they have the same ability that the original card would have. When the card dies, then....well..... it dies, simple as that. But if it turns into a pheonix/minor pheonix and when it dies then it turns into Ash then it will turn into Ash. As the card is turning into other creatures the immaterial is still in effect. Back to if the card turns into a pheonix and it dies somehow, by a Fire Buckle or something the the card turns into Ash and you can use the ability to turn it into a pheonix again. The cards Metamorphis ability is no longer in effect.
Picture: I kind of was thinking of a swirl pool with shapes of creatures in it. But i dont know how to do that =(
