The monster zone the monster removed by “Dimensionhole” will be considered occupied. Monsters may not be summoned or Special Summoned into this monster zone.
Tokens may be removed from play through the effect of “Dimensionhole,” but will not return to play.
If the Standby Phase the “Dimensionhole” would return the monster in is skipped, “Dimensionhole’s” effect disappears and the monster remains removed from play.
Netrep Q&As:
Q: If an end of turn effect is scheduled for a monster (as in being destroyed) and you use “Dimensionhole,” is it applied when the monster comes back into play?
A: It is not destroyed and it is “reset” after it comes back. bishop, 12/05/2003
