Jack had a trap called Monster Baton which let's a player discard a monster card when they activate it so that later in the duel, they can discard a monster card with the same level as the original monster card to give another monster the effect of the original discarded monster.

Crow used Pic related to activate Monster Baton and Yusei discarded Earthquake Giant to give his Shooting Star Dragon the effect to negate battle damage and blow up the monster it battles with after the battle. Zushin couldn't negate this because of a loophole with its effect only negating the monster it battled and not the effect a monster gain from a trap copying a monster's effect.
