In episode 177, Nightshroud uses this card during his Duel against Jaden Yuki. He discards this card in order to activate the effect of "Darkness Outsider". Nightshroud then activates this card's effect. In the next episode, Nightshroud Special Summons this card during his second Standby Phase after the activation of this card's effect. Due to "Darkness Seed" being Special Summoned through its first effect, it gains two additional effects. On Nightshroud's End Phase, this card makes Nightshroud's Life Points 4000 as they were under 4000 at that point. "Neos Wiseman" then attacks this card, but this card isn't destroyed in battle due to its first granted effect, however Nightshroud still takes Battle Damage. "Neos Wiseman" then inflicts damage to Nightshroud equal to the ATK of this card and increases Jaden's Life Points by the DEF of this card. On Jaden's End Phase, this card makes Nightshroud's Life Points 4000 as they were under 4000 at that point. Nightshroud then Tributes this card in order to Tribute Summon "Darkness Bramble".
