The members of the archetype follow the naming pattern "Windwitch - [word relating to ice or cold] + Bell". 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 (Glass Bell and Ice Bell) or a literal bell (Snow Bell). The Extra Deck monsters, on the other hand, have appearances consisting of a mixture between a jet-like figure and a bell, all with a feminine appearance.
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.
