This is Icybraker here, posting his shield to be submitted in the Shields competition.
As you all possibly know, I love Aether, and Aether has some of the least amount of cards out of all the elements in the game. Additionally, the Spark seemed like a card that needed some more combos attached to it. I put two and two together, and, viola, the Energy Shield.
It brings retribution to attackers, especially mobspammers, by giving you a 50 % chance to generate a Spark with every attack. Obviously, Momentum bypasses the shield, but otherwise, a good way to add some muscle to the Aether element.
