Here are the powerful cards you should be looking for to add to your battle deck collection, and what cards you should definitely be watching out for as you play online. Goblins Goblins are super cheap and useful for just about anything. Individually they are weak, but together as a group they do serious damage. They are great for defending against enemies and joint attacks on enemy towers and units. Most battle decks will include Goblins because of how they are cost efficient and adaptable. Spear Goblins Spear Goblins are real cheap in elixir cost, but have a lot of payoff when used right. It summons three goblins that come with throwing spears. They can attack from close and long range. Spear Goblins can also attack ground and air units. They are much like their Goblin counterpart in usefulness. Archers Archers are great long range attackers that can damage both ground and air units. As a pair of bowman, they can defend or attack towers pretty well. Archers are great for defending against slow attacks, like Giants or anything similar, from a distance. Archers attack frequently with a barrage of arrows aimed at enemies. Their low elixir cost makes them a great unit to have in any kind of battle deck when playing online. Baby Dragon The Baby Dragon is a great card for a number of reasons. Not only does it fly above units that can't attack air troops, but it also deals damage over a wide area with it's fireball. This can be great for taking out groups of goblins, skeletons, and even damaging towers and buildings pretty good. The 4 elixir cost is great, since it has the ability to attack air and ground units and be something to spook your opponent into reacting wildly. Dark Prince The Dark Prince is a great card for taking out groups of enemies on the ground. Unlike the regular Prince, the Dark Prince cost less elixir and is still strong against enemies. The Dark Prince doesn't deal as much damage to buildings and towers as the Prince, but he has a high defense. If you find yourself facing a large group of enemies, or your attack is being defend against with a group, then the Dark Prince is great for regaining control of everything. Hog Rider The Hog Rider is incredibly powerful when launching attacks against enemy towers. Hog Riders make a direct route for Towers and deal lots of damage to them. They only cost 4 Elixir and can really make a huge impact on matches. Hog Riders also have a decent amount of HP, making them a solid offensive card to have. When you find that your enemy has less towers than you, place a Hog Rider on the field. Barbarians Barbarians are great for launching coordinated attacks on enemy buildings and towers. Barbarians attack in a group and have a a lot of HP. When together they great damage output. Barbarians can bring down tough units fast, making a clear path for you to attack enemy towers. Strong enemy troops won't feel like such a big threat when you have Barbarians around. Prince The Prince is great for charging at enemy towers and dealing heavy damage to them. When not engaged in battle, the Prince will charge directly at the nearest tower and take a huge chunk of health out of it. It deals more damge after charging than being stationary and attacking. The Prince also sports a high defense when fighting enemies. It can power through most weaker units with ease. Although the Prince can't attack units in the air, it can quickly shift the momentum of a match in your favor early. The Wizard Wizards are very powerful. Unlike the Witch that summons skeleton minions, the Wizard attacks and deals a lot of damage over a wide area. This is very helpful against players with a lot of troops on the field. The Wizard also has good damage output to stronger units that may be a threat. Wizards are great for taking out buildings that spawn multiple enemies, such as Goblin Huts. If you want to clear the field from weak enemies, then you can't go wrong by using a Wizard. Minion Horde The Minion Horde is a counter any immediate threat to your Towers. While the elixir cost is high, the damage output of the minion group is also high and great for destroying incoming powerful enemy units or groups. Unlike other troop cards that last longer on the field, a Minion Horde is solid quick defense or extra push to destroying enemy towers. If a match is close to ending, using the Minion Horde may give you the extra edge you need. Giant Skeleton The Giant Skeleton works a bit better than the normal Giant card. The Giant Skeleton can attack other units on the ground and air, but also drops a large damaging bomb when defeated. The bomb left behind after deals great damage to towers and buildings, making it helpful to launch a Gaint Skeleton against weak Towers. The elixir cost is a higher than a Giant, but the extra benefits with it are more than justified. The Golem The Golem is one of the most expensive elixir costing cards in the game, but its also one of the strongest. The Golem can attack units and deal heavy damage to buildings and Towers. This thing is a monster to almost anyone. When defeated, the Golem will spawn smaller golems in its wake, making it a viable threat when placed on the field. The best time to place a Golem is when you have an opening on a weak enemy Tower, turning the match in your favor immediately when it spawns. Spells Arrows Arrows are a staple to almost every deck you will face online. Arrows are great for taking out groups of small enemies that are weak and could quickly dispatched. You can deal some extra damage to towers and buildings, but Arrows are more effective at preventing groups of enemies from storming your side of the field and damaging your towers. Fireball Fireball is another staple for most battle decks. You can obtain it early and use it in a variety of ways. The splash damage from a Fireball is not as wide as the Arrow card, but the damage output is stronger. Fireballs can take out most strong troops on the field, but they can also be used to damage buildings and towers. Matches may get tense and very close, only to be ended by a Fireball launched at a weak tower. Don't be afraid to use a Fireball card when you have the chance to do so, especially if it means achieving a swift victory. Poison The Poison spell card is a great defensive option against attackers. When cast, a cloud of gas slowly damages units over time and slows down their mobility on the field. This can be a great card when you see attackers getting dangerously close to your towers. Slowing down enemies leaves them open to attack from your towers and from your troops already on the field. Buildings Tesla The Tesla is a very powerful defensive building. It not only hides underground, avoiding most area attacks, but it deals a lot of damage to units that happen to pass by while atatcking your Towers. A Tesla needs to be actively above ground in order to be destoryed. A Tesla can effectively damage both ground and air units, making for a solid defense against any kind of onslaught. Most decks that have a defensive strategy against opponents will more than likely have a Tesla included. Goblin Hut Goblin Huts are great for having a steady stream of units appear on the field. They continously spawn Spear Goblins for a set amount of time. Most players that favor rushing down opponents will have a Goblin Hut alongside other Goblin cards in their deck. Placing a Goblin Hut on the field can be helpful to keep your opponent distracted while you save up elixir and attack other areas.
