Tag monster

Tag Monsters are effect monsters with "Tag" ability.

The effects of Tag Monsters can only be applied if you control 2 or more Tag monsters. While you control 2 or more of them, they can share their effects with one another. Such as if you control a monster with the effect to not be destroyed by battle and control another control with the effect to make a second attack during each battle phase, both monster gains each other effects while on the field.
