This is one of the oldest elixir golem decks in the game. Just like other elixir golem decks, this one is all about keeping your push healthy. The difference is that this deck has the heal spirit instead of the rage to supplement extra healing. Use the barb hut to bank up your elixir and have a strong defense. The tornado is especially important as it synergizes with both of your dragons.
The elixir golem is the main win condition. If you get him to the tower he will drop it very quickly. Support him with every other card in your deck.
The Battle Healer is literally the lifeblood of this deck. It is important to use your tornado to pull things into her to make sure she is healing your push.
The edrag is so good at stunning everything and keeping your push alive by resetting cards back to the elixir golem after each stage.
In the early stages of the game, play fairly passively and focus on using your barb hut on defense. If you ever find yourself in a spot where you have a good defense you can always counter-push with an elixir golem at the bridge.
In the later stages of the game, you can start to build up elixir golem pushes from the back. For it to be a successful elixir golem push you have to have the healer and the electro-dragon involved. There is no such thing as a halfsies E-Golem push.
