One of the arguably best examples (which can be observed as early as the reverse version of the Yami Yugi vs Bakura duel in Campaign) is if they are below 1000 LP and decide to send several monsters to graveyard (be it by fusion summon or tribute summon, for example) while you have multiple Coffin Sellers active, which deal 300 damage each whenever your opponent sends a monster to the graveyard
