Fist of all, thank you @kephler for hosting this contest. My entry is based on the character - Jon Snow from Game of Thrones. I think it's cool to have a roar effect that summon's a Wolf and a sword which also was based on Jon's direwolf "Ghost" and his sword "Longclaw". The Ward and Protection is similar to the Highborn Knight card.
There's a couple of GOT character's that might also be worth making a GU card. Arya - can be an assassin on Deception, Danaery's as a War creature and the Night King as a Death card. I might make a set of custom cards based on these GOT characters in a future post. But for now, this is my official entry for the #MyGodsUnchainedCustomCard contest.
May the mulligans be in your favor!
