Today we have Sweep on the channel sharing his #1 deck right now which is this goblin giant sparky deck. Try to use this deck aggressively and you should aim to control the tempo of the match. You have lots of units to lightly defend the opposite while you build up an unstoppable push in the other lane. If your opponent has zap, e-wiz or e-drag try to bait out these units or protect your sparky from them as much as possible. The mini pekka and sparky are both great tank killers, use your musketeer and fisherman as support cards and protect them as much as possible.
Fisher-mans unique ability allows him to pull any unit in the game, this makes him great for activating your king tower and pulling units like hog rider, ram rider, golem, giant etc away from your towers. You can use him to pull units into the blast radius of the sparky or you can also use him to protect your goblin giant or sparky. This works well against mega knight, pekka, price etc.
Goblin giant is your main tank inside this deck and the two spear goblins on his back help protect your push from swarm units like bats, skeletons, minions etc. This card is actually a great graveyard counter due to the two goblins hitching a ride. I like to use him at the bridge in most match-ups rather than starting a push with him in the back. Playing him in front of your counter push units is the best way to use this card. He's also great on defence and can offer a lot of value for six elixir.
Musketeer is your main defensive units against air units, protect her and keep her alive as long as possible. Use her range to help snipe units across the bridge and support your sparky on offence.
Early game you should aim to activate your king tower at the earliest opportunity by using the fisherman. Learn what deck the opponent is playing, use the sparky of defence and apply light counter push pressure in single elixir. For opening plays you can start out with the spear goblins or cycle fisherman in the back.
In double elixir you can begin to support your pushes a lot more and use your spells more on offence. Keep supporting your pushes at the bridge and trying to get as much tower damage as possible. I highly recommend watching sweep play in the video to watch his decision making and how he pressures with this deck.
