What makes this deck great is that there is only one legendary, the lavahound. Also, many of the cards are replacable, making it very flexible and to your liking. My version is for arena 8 plus, but lower arena players can still use different variations. Without any more talking, lets get into the deck!

Lavahound
The main win condition of the deck, and also the tank for your air pushes. There are no other air tanks in the game, making this card irreplaceable.

Balloon
The secondary win condition, and the main damage dealer. If it gets to your opponents tower, it will to crazy damage. This card is also irreplaceable.

Baby Dragon
The AOE air attacker, good at shutting down swarmy pushes, and protecting your other air units from swarms. Like the balloon it is available from early on in the game, so most poeple should have unlocked it by now. If not you could try a wizard/ ice wizard, but they are not ideal.

Mega Minion
One of the most used cards at the moment, and for good reason. It cant be fireballed and when paired with the baby dragon it is hard to counter. A good replacement would be minions.

Ice Golem
Mainly used on defence for its tanking, distracting and freezing purposes. It can't defend on its own however, and needs to be paired with something else. Other good replacements are knight, and potentially valkarie, although they raise the average elixir cost.

Skeleton Army
Also used on defence to counter high health troops, and keep them busy for a while. It can be replaced by almost any other cheap distracting troop, such as guards and spear goblins, although skarmy works best.

Cannon
The defensive building in the deck. Could be swapped with tombstone, but the cannons ability to counter the hog rider, and deal more damage overall makes it my prefered choice.

Zap
Versatile spell used to reset infero towers, sparky and change the focus of enemy towers, whilst also being able to take out swarms of enemy troops for a low cost. Can be swapped with log or arrows.

Tactics - How to build an attack
You may want to wait until double elixir time before you start building a big push, but that isn't always necessary.
I usually either place the lavahound in the back right tile, and wait for it to reach the bridge before joining it with a baby dragon and mega minion. If necessary I will then add the balloon into the mix, or I will send it down the other lane to finish off t
