This is my first contest and I was scrolling around when I saw the OLD Elder Dragons and thought, "I wonder what's the next thing Wizards will do with those guys." So I then thought, "Why does Wizards have to decide? You guys can!". Anyway, some general flavor information can be found here: http://mtgsalvation.gamepedia.com/Nicol_Bolas
The contest will to create a specific Elder Dragon (which looks cooler than these ones) as a creature and/or planeswalker. Keep to the same colors and feel as the originals. Besides that, no restrictions!
Here is a list of all 5 Elder Dragons to choose from:
