To start of, I would like to specify this deck as a "Counter attack-ish" deck, for these reasons:
You will 80% wait for your opponent to spawn, then quickly decide which card to use to screw up their decision.
Goblin: You can use this card to lure tanks away from your towers, which also might make them suffer attacks from 2 Crown Towers
Valkyrie: Of course, a mini-tank and ground AOE dealer for swarms
Hog Rider: To push Prince, Knight, Mini PEKKA, PEKKA,... away from your Crown Tower, EVEN IF THEY ARE TARGETTING IT and switch their target to the Hog
Freeze: Well...Just freeze them if there is a "Tower Targeter", such as Hog, Giant, Golem, Balloon, or a swarm
Barbarians: Works really well against tanks and most ground troops
Minions: This card and Horde will both vanish with an Arrows, and most players have Arrows or Fireball in their deck, so why even bothers wasting 2 extra elixirs? This card works just as well if you are facing flying troops and don't have Wizard: Just let the Tower take some hits and let the Minions do the rest for ya.
Lightning: For defense, this card is my favourite when they put a combo like Prince + Tank + Witch,..., basically when they put 2 or more high HP troop in the same lane
Wizard: Swarm, Flying, Musketeer, Baby Dragon, this man doesn't give a damn.
Those are the basic moves for defending, now to attack:
Hog + Freeze : Wait for your opponent to spawn first, then put Hog in the other lane, then wait until they've spawn to stop this Pig Rider, immediately Freeze, or if you must defend the other lane, let Hog be, he would still take some HP from that Crown Tower for ya
Goblin + Valkyrie: Put Goblin in the corner of the arena and Valkyrie near the bridge, those Mini-Hulks will push Valkyrie up to tank for them, and this combo will only be defeated by flying troops
Minions, Lightning: Ya see, most Hog + Freeze user must have some tricks up their sleeves, or Bomb Tower and such will be a major disadvantage for them, so I included Minions and Lightning to help exterminate those stupid towers, and also Lightning has some really decent damage to finish off a 200 HP Crown Tower, securing your victory.
Barbarians and Wizard can easily fit into any combos, or forming a combo of their own, that is 100% up to you.
* REMEMBER: THIS IS ALL MY PERSONAL EXPERIENCE, YOU CAN ALWAYS MAKE CHANGES TO SUIT YOUR STYLE.
