On 12/6/17, a Balance Update decreased the Night Witch's Bats spawned upon death by 1 (to 3 from 4), increased Bat spawn speed by 1 sec (to 6 seconds from 5 seconds), and initial Bats spawn slower.However, this was not exploitable like the Electro Wizard Tournament as the Night Witch Draft Challenge had one-time rewards. If the player achieved 12 wins, they obtained the Night Witch two days early. In this challenge, gameplay was similar to a regular Draft Challenge, except that one of the players was able to choose who would use the Night Witch. The Night Witch was once available in the Night Witch Draft Challenge which started on 29/5/17.The Night Witch card was added to the game on 31/5/17.On the contrary, she also pairs very well with the Lava Hound, due to spawning air swarms that can handle cards that could threaten the Lava Hound, such as a Mega Minion. Those Bats will get distracted by the Lava Hound, defeating both the Lava Hound and the spawned Lava Pups. Place her in the back, in the same lane as the Lava Hound, so that she spawns as many Bats as possible. Despite being unable to target air troops, she is very effective at weakening a Lava Hound.Troops with a chain attack, such as an Electro Dragon or an Electro Spirit are very effective at defeating the Bats spawned from the Night Witch, weakening her significantly when fighting against other units.On the other hand, the Night Witch's high melee damage, increased health and her faster Bats make her more threatening on a counterpush. The Night Witch does not do splash damage, only spawns two Bats at a time, is very fragile without the help of a tank unlike how Witch could protect herself using the spawned Skeletons, and cannot target air troops. The Night Witch's role in a deck is fairly different compared to her counterpart, the Witch.Her first wave of Bats don't spawn and attack quickly enough to prevent the Balloon's first attack, even when she is placed slightly in advance.
Just like the regular Witch, if the Night Witch summons Bats while under Rage, her Bats are also affected.If timed correctly, not only will the Poison cripple the Night Witch, it will also eliminate all the spawned Bats. Poison is the most effective spell against the Night Witch.Ranged splash damage troops like the Executioner, Wizard, or Witch are very effective against the Night Witch since they can defeat her and her spawned Bats quickly without receiving much damage.The Golem is great when used with the Night Witch because it can tank for the Bats spawned by her and deal massive damage to towers.However, if these units are distracted with something else, the Bats may heavily damage or even defeat them. The Night Witch cannot attack air troops, so Minions or the Baby Dragon will be effective at taking her out since they can also easily take out her summoned Bats.
The Night Witch's high damage per attack in addition to her continuous spawns make her potent at defeating high-health units, whether it be on offense or defense.However, the Night Witch can defeat nearly all cards that cost 6 Elixir or below, like Sparky, the Lumberjack, Wizard, etc. She cannot perfectly counter some troops that the Witch can, as the Night Witch cannot distract ground-targeting troops with her Bats.Night Witch card costs 4 Elixir to deploy. She is a single-target melee troop with moderate hitpoints and moderately high damage. The Night Witch card is unlocked in Serenity Peak (Arena 14) or a Legendary Chest. If you get too close, she isn't afraid of pitching in with her mean-looking battle staff.”
