The original card had "you draw two cards and lose two life", "destroy target creature," and "cast a spell without paying its mana cost." The last ability was both too powerful and not really black (black could cast a spell out of a graveyard)
Although this effect continued up to Kamigawa: Neon Dynasty , with the hotness Hinata, Dawn-Crowned (Hinata makes a great commander by the way), a different approach to this design space was needed to get to wards final form
Absolutely, a flashbacked spell counts as casting and resolving a spell
For , Gifts Ungiven is Intuition but you get to snag one more card...sort of
Nuff said, bub
Tamatoa Happy as a Clam is a 6-cost Character with 4|5 stats, when played, itll let you add 2 item cards to your hand from your discard
