Other than companions, which had their own problems, and Grief, which can be cast for free, White Plume Adventurer is actually the highest mana value creature banned in Legacy
It works well alongside other value lands that go to the graveyard, like Kamigawas channel lands or Strip Mine and friends

One of the best artifact creatures in Magic, its a perfect fit for 5-color decks, helping your gold creatures become stronger

Static and triggered abilities are unaffected by Hold for Questioning
