Hello, my name is Clash Royale PC and this is my first time doing this.
Anyways, my deck contains only 1 legendary which is very easy to change.

My deck contains the following 8 cards:

Ice wizard: This card is crucial when it comes to defense because it is so good in every type of push. It gives great value, even when it is lvl 1 because with that slow effect, it gives more time for the other cards to annihilate the push that your opponent sent. ( Use it for defense always and if they send a hound, cycle to it). If you do not have this card, I would suggest to switch it for a musketeer or archers because those cards will be great in defense.

Giant: This card is the meaty shield for every thing. If you start out with giant balloon and arrows, I suggest that you wait until you have 10 elixir. Once you do, put the giant in front of the crown tower. Once the giant reaches the bridge, place the balloon on the right side of the giant, but a bit behind it. Always do this so the troops placed by the opponent will attack the giant. Always have your arrows in hand when pushing because the opponent might have a skarmy or minions.

Balloon: After the buff, this card is your heavy hitter and please, please do not send it alone because the opponent will destroy it and they will adjust your cycle so they can always counter the balloon. Do not use the balloon as a card to distract cards because it will die. And the opponent will laugh at you.

Arrows: For 3 elixir, this card is very good because it one shots minions, which counters the balloon and after the zap nerf, I highly suggest to not put it in the deck, because cards such as minions, archers, and princesses will live.

Inferno tower: For 5 elixir, this card is actually really good. People like to use tombstone or cannon but I like the inferno tower because of the high DPS after 2 or 3 seconds and other defensive cards are fragile, they would break down after 2-3 giant hits but the inferno will live for a while, even with lightning it will still do a decent amount of damage.

Ice Golem: Even with the nerf, I still think this card is very good because in legendary arena, many people use Ebarbs even after the nerf and it is very easy to kite them with the ice golem then place the ice wizard. 6-6 elixir, even trade and with the ice wizard, you can make a potential counter attack with an immediate giant balloon.

Skarmy: This card is very good in defense against pushes like Ebarbs and ice golem because the ice golem drags the Ebarbs awasy and the skarmy takes care of it, but if they zap, you have the ice wizard. It is also good with inferno tower because if they zap the inferno so the giant would live, you could easily put down the skarmy for either the supporting troops or the giant.

Minion horde: This card is very good when it comes to baiting the zap for the inferno tower because if they zap the horde, the inferno tower will stop the push. If the opponent places Ebarbs and fire spirits, just do ice golem and horde. It can also be good against air attacks like lavahound and balloon with the ice wizard and the inferno tower.
I really hope that you guys have success with this deck and if you have any questions, feel free to comment below or email me so I can help you ( this deck works even without the horde if you have it under leveled, use minions or spear goblins.
