Common Card: The Royal Giant
We all love the Giant as he focuses on destroying enemy defensive structures. Now, imagine the same mechanics but this time, on a ranged unit. If you want to tactically attack those crown towers then you would surely love the Royal Giant. He appears as if the well known Giant had a total make over because of all of the added accessories such as the earring, dark colored cloth, and facial hair, which even includes sideburns. The Royal Giant is indeed a man of pure strength. He lifts a cannonball on one hand and a cannon on the other side. The cannon that he wields appears to be that of a level 7 cannon in the Clash of Clans game.
The Royal Giant can do his duty quite well when a distraction is caused on the other lane. The Royal Giant can handle a good amount of punishing, as he has sufficient health points for tanking. Still, he can be taken down by those spawners or high damage attackers. If played well, his moderate damage created by firing shotgun blasts on to the enemy structures can slowly take down the crown towers. Most people do not want to use such a card because of being slow. But, just like the giant and the Golem, they do serve their purpose well.
Another great combination is having the Princess behind the Royal Giant. She shoots her flaming arrows from a distance and with another ranged unit up front. That incredibly can withstand decent amount of damage. The crown towers are no match against the two paired up. However, the Royal Giant comes weak against spawners and all sorts of mobs as mentioned earlier. This has a simple solution and that is to have a wizard or even just a bomber on his back in order for those pesky spear goblins and barbarians to be eliminated easily.
The Inferno Tower is feared by the many tanks in the game. It could also take out the Royal Giant if he catches him pushing his way to the crown towers. However, those fiery flames that the Inferno Tower throws upon cannot reach the range of the Royal Giant. So as long as the opponent places the Inferno Tower first before you deploy your Royal Giant, then it would be an easy take down.
You might wonder how the Royal Giant would serve as a defensive troop as it mainly focuses on structures. Now, going back to his stats, he has a great amount of health points and can serve as a temporary tank. You can place Guards before the Royal Giant and then back them up with cheap damagers such as the archers or spear goblins. This way, the Guards would be able to do the pre tanking phase, followed by the Royal Giant taking minimal damage as it already reaches the crown towers of the enemy. Thus accompanied with a few other common cards turns a defensive tactic into a massive push.
