The monsters of of this archetype follow the naming pattern "Windwitch - [noun] Bell", where the noun is a word relating to cold or a transparent item (e.g. "Snow" and "Glass"). Visually, all of them have a big bell somewhere on their bodies as accessories. The Main Deck monsters shown so far have the appearance of either a stereotypical magical girl riding on a broom-like bell (e.g. "Glass Bell" and "Ice Bell") or a literal bell itself ("Snow Bell"). The Extra Deck monsters, on the other hand, have more abstract-looking appearances consisting of a feminine figure with bells and jet aircraft parts integrated in the body.
The "Windwitch" monsters focus on a burn strategy. Their effects also have restrictions based on the WIND Attribute, similar to the "Speedroid" archetype, which, combined with the fact that not only are both archetypes geared towards Synchro Summoning, but the anime users of both archetypes had a very strong connection, implies that Windwitches are designed to be an engine that can be teched into a "Speedroid" Deck and vice-versa.
In the anime, the high-Level monsters can copy the effects of monsters in the Graveyard, allowing the user to keep indirectly reactivating the burn effects. The real life versions instead have "Winter Bell" focuses on swarming and burn tactic, while the effect "Crystal Bell" is toned down to user's turn only but also capable of copying the monster's name.
