"'''Charmer'''" ("'''Spirit Charmer'''" ({{Ruby|霊|れい}}{{Ruby|使|つか}}い ''Reitsukai'') in the ''[[OCG]]'') is a [[series]] of six [[Level]] Level 3 [[Spellcaster]]-[[Type]] [[Flip Effect Monster|Flip Effect]] [[Monster Card]]s with 500 [[ATK]] and 1500 [[DEF]]. There is one "Charmer" for each main [[Attribute]]. The [[Card effect|effect]] of each "Charmer" allows it to take control of 1 opponent's face-up monster of the same Attribute as that "Charmer" for as long as the "Charmer" is [[face-up]] on the [[Playing Field|field]].
The original four "Charmers", "Aussa", "Eria", "Hiita", and "Wynn", were first released in ''[[The Lost Millennium]]''. Two packs later, in ''[[Elemental Energy]]'', they had their "[[Familiar-Possessed]]" forms released, and their final forms were released two packs after that, in ''[[Enemy of Justice]]''. "Dharc" and "Lyna", however, do not follow this trend; "Dharc", which was released in ''[[The Duelist Genesis]]'', did not get his "Familiar-Possessed" form until ''[[Order of Chaos]]'', some 14 packs later; and "Lyna", which was released in ''[[The Shining Darkness]]'', still doesn't have her "Familiar-Possessed" form; neither of them have their final form yet, either. "Dharc" appears to be the only male "Charmer" in the series.
Each "Charmer" features a familiar, a Level 1 or 2 monster with the same Attribute as the "Charmer".
