Special Summon 1 Beast-Type, Winged Beast-Type, or Insect-Type monster with a Level equal to or less than the Level of the Tributed card + 3 from your hand or Deck to your side of the field. When this card is removed from your side of the field, destroy the monster.
Soul Resurrection
Continuous Trap
Special Summon 1 Normal Monster from your Graveyard in Defense Position. When this card is removed from the field, the monster is destroyed. When the monster is destroyed, destroy this card.
with all of these cards, if the special summoned monster/s is/are:
- flipped face down (book of moon, darkness approaches etc.)
- removed from play temporarily (interdimensional transporter, the monster is strike ninja and his effect is used)
- if a royal decree resolves or jinzo is special summoned
- tributed (tribute summon, tribute for cost, tributed for special summon)
the trap card will remain on the field meaninglessly.
when the monster/s is/are returned to a face up position on the field, the trap card will not re-target it/them.
so the trap card is eligible to be returned to your hand (giant trunade) and the monster/s will be unaffected by the trap leaving the field.
