This is a very expensive Giant Sparky Graveyard beatdown deck. When you put all three of those cards in the same push it becomes almost impossible to stop. The arrows is the only spell in the deck so it is important to try to save it for offense to ensure that your Graveyard is able to break through when you go for it.
The Giant is the main tank for this deck. Use him in front of the sparky and as a tank for the Graveyard to make the unstoppable push!
The zappies are the best on defense and provide a fireball bait that synergizes with the barbs and the hunter.
Arrows are your only spell so make sure to choose when to use them wisely.
In the early stage of the game, play reactively and try to get a positive elixir trade in order to start your push with a sparky or giant in the back.
In the later stages of the game, you will have enough elixir to be able to counter push. So if you ever have a good defense with counter-pushing units don't be afraid to go in for a Giant + Graveyard in front!
