Its long range, area damage, ability to attack both air and ground units, and ability to deal double damage can allow it to become a decent alternative for a Witch or Wizard in a Giant Combo.
Although his range is 4.5 tiles, his axe throw actually reaches 6.5 [confirmation needed] tiles away, allowing him to damage other units that are just behind his targeted unit. His aggression range is 4.5 tiles, so he will have to walk up to the enemy before hitting it with his axe, even though the axe can reach troops 6.5 tiles away.
Taking this even further, when the axe is flying through the air it has a 0.9 tile radius. Thus, the Executioner can technically reach 7.4 [confirmation needed] tiles.
His hit speed comes in two parts: his axe travels for 1.5 seconds and after the axe returns to him there are another 0.9 seconds where he does not attack. This sums up to an overall 2.4 second hit speed.
Rage and slowing effects only affect the 0.9 second portion of the attack where he is not attacking and does not affect the 1.5 seconds in which the axe is in motion. Hence, Rage and slowing effects do not greatly affect the Executioner's damage output as they only change the overall hit speed by about 0.3 seconds.
Because of its damage and other perks listed above, countering swarms with the Executioner can also be extremely effective. However, keep in mind it has a very slow attack speed (2.4 seconds), almost as slow as a Bowler's.
The Executioner has moderately low damage per second, so medium-hitpoint units such as Mini P.E.K.K.A. or Knight can counter him.
Since the Executioner has a linear attack similar to the Bowler, he can attack glass cannons that are behind a tank.
Like the Bowler, when the Executioner lands the final hit on a Tombstone, he will not only destroy the Tombstone. He will also take out the spawned Skeletons immediately.
The Executioner pairs well with the Bowler as the Bowler can take care of ground swarms and the Executioner can help the Bowler with ground troops and defend against air swarms. This combo is also durable, surviving Fireball+Zap or Fireball+The Log. It is, however, vulnerable to a Rocket.
The Executioner was added to the game on 27/1/17.
On 13/2/17, a Balance Update decreased the damage of the Executioner by 6%, the range to 4.5 (from 5), and the axe hit radius by 10% (from 1 tile to 0.9 tiles).
This update also fixed some glitches where the Executioner's axe would hit enemies behind him, would do damage in front of him when the axe was at its farther and cause a small stun when it hit enemies.
It has the same Elixir cost, card rarity, and linear attack of the Bowler; however, the Bowler has more health, cannot hit air, and can knock back units with its attack.
If you look very closely the Executioner actually deals knockback and stuns. It actually resets some troops' attacks, but will not reset any charge attack. However, the developers have confirmed that this is a bug.
The Executioner is the only card that deals damage twice per attack.
Because he can attack twice, he can sometimes hit an enemy that has not been damaged by his first throw.
If he dies while his axe is not in his hand, the axe will fly back to his dying tile and deal damage to whatever is there. This is also true if he is frozen.
