Ouchian Bargain with reduced cost mischief.

Typically, when a card refers to the Gold Cost of another in-play card, it means the modified gold cost, which is what was paid to bring the card into play. Once a card goes out of play, all modifications are cleared, and you'd be referring to the printed value (as there aren't currently any cards that modify the cost of out of play cards).

I don't think this is the case, since if you use Staff of Magic to reduce Kaboom! to 3 gold then play Forked!, you still need to pay 5 gold for the Forked! version of Kaboom!
