This deck is very simple... 1) Place an elixir pump 2) Defend 3) Build up a giant push in the back 4) repeat steps 1-3.
The pump is very important in this deck, place them and protect them to build up an elixir advantage.
The rage is the second most important part of this deck. Build-up giant pushed in the back and rage everything at the bridge to break through easily.
In the early stages place pumps and have a good defense. You can giant in the back to try to convert positive elixir trades into damage
In the later stages of the game, you can do the same thing as you do in single but you have will have more elixir influx so you can make your pushes even bigger and support with more spells.
