The super card specially created for Clash Royale this season is Super Witch. This powerful summoning unit creates all the troops usually spawned by the three existing witches. So different monsters appearing for no reason can be an absolute nightmare for your opponents. But you know what? In this challenge, all users must play it. No envy, so you have to form a deck that is more efficient than everyone else around this super witch.

Below are the decks with the highest win rates for that particular challenge.
with giant noble deck
super witch
giant nobility
a bolt of lightning
log
fisherman
hunter
Skeleton
electric spirit

A reasonably primitive deck but very effective. However, he will ask you to train with him during the first part of the challenge.
Hunter is rarely used commonly but is a particular counterattack from Super Witch.
Lightning Golem Mallet
super witch
Target
a bolt of lightning
baby dragon
stone
bombing
tornado
Skeleton King

A classic control platform framework. Golems will be excellent support for your push
Back up your Golem with Baby Dragon and Bombers, so you don’t get overwhelmed
Poison Graveyard Deck
super witch
cemetery
poison
tornado
Skeleton King
stone
baby dragon
Barbarian Barrel

The poison and tombstone combo makes it difficult for your opponents to defend with your super witch. The troops you summon will melt before their eyes.
On the other hand, this deck is quite vulnerable defensively. Use barbarian barrels and tombstones wisely to slow down enemies and jam them with your very own super witch.
