The Hog Rider is a Rare card that is unlocked from the Builder's Workshop (Arena 5). He is a quick, building-targeting melee troop with moderately high hitpoints and damage, and able to jump over the river. He appears as a man with brown eyebrows, a beard, a mohawk, and a golden body piercing in his left ear who is riding a hog. A Hog Rider card costs 4 Elixir to deploy.
Strategy
When he is jumping over the river, he cannot be targeted by any ground attacking units. The Log and Earthquake will fail to damage a Hog Rider while he is jumping. Air troops can still attack him though, and the Inferno Tower and Inferno Dragon will continue to ramp up their damage.
When countering the Hog Rider, using buildings would be your best bet. But be wary, as the offender will usually play around it with cards such as Earthquake. Air swarms such as Minion Horde can also help due to the Hog Rider's usual support cards not countering them.
On the offender's side, a powerful move is to accompany him with an Earthquake, obliterating almost every building, and also grounded swarms. To a lesser extent, Lightning could also be used, retaining the same point of almost destroying every building while also crippling troops such as the Wizard or the Hunter.
Using The Log to predict a Skeleton Army or even a Tombstone will let your Hog Rider keep most of his hitpoints and your opponent may not answer in time, letting your Hog Rider connect to the Tower.
The Hog Rider can be paired with the Lumberjack as both a swarm bait and damage combo. It is a very fast combo with an extremely high damage output potential, so the defender will likely try to counter it with a swarm. If this happens, the attacker should use a spell like Arrows to render the defender poetically defenseless. If they manage to defeat the Lumberjack, the dropped Rage will make the Hog Rider even more dangerous than it normally is.
A fast and deadly combination is the Hog Rider and Mini P.E.K.K.A combo. Both units are fast but the Mini P.E.K.K.A does much more damage and does not attack only buildings so the Mini P.E.K.K.A can deal with troops like the Executioner and Musketeer. However, this combo can be defeated with swarms like Skeleton Army, as the Mini P.E.K.K.A cannot handle swarms. They are also unable to target air troops, so the Minion Horde can stop this easily.
A Hog Rider combined with a Goblin Barrel can be awkward for the opponent to defend against. Timing it so that the Hog Rider is tanking the tower shot
