Rulings
- Destruction Jammer cannot be chained to effects that may or may not destroy a monster, like Acid Trap Hole, Blowback Dragon, Magical Dimension, Reign-Beaux, Overlord of Dark World, Snipe Hunter, etc.
- Destruction Jammer cannot be chained to the activation of the Ignition-like effect of a Continuous Spell or Trap Card (like Skull Lair, etc.).
- Destruction Jammer cannot be chained when Premature Burial or Call of the Haunted is activated because they do not destroy a monster card at that time, nor can it be chained when the Special Summoned monster is destroyed.
- Destruction Jammer can be chained when Light and Darkness Dragon's effect to Special Summon a monster is activated, but not if the owner of Light and Darkness Dragon has no monsters on their side of the field.
