These monsters have the theme of being displaced through time and space and forced to adapt to their new environments, as well as deal with various changes to themselves, such as body modifications, age manipulation, and alternate versions.

Play Style
Timeshifted monsters work very similar to Toon Monsters and s. They require a Field Spell on the field, or else they are forced to Tribute themselves, though whenever they leave the field, they are placed on the bottom of their owner's Deck. They can also be Special Summoned instead of Normal Summoned, though they require Tributes to be paid for Level 5 or higher monsters. However, their signature Field Spell, "Time Shift Zone", allows for Timeshifted Monsters to be Special Summoned without Tribute once per turn.
