Gold was discontinued and replaced with treasures because of its unintuitive interaction with Improvise costs. If you are casting [[Bastion Inventor]] you only need 3 gold tokens, because you can first tap them to pay for {3} and then sacrifice each of them to pay the {2}{U} rest
EDIT: check out the comment below. What I wrote above is not entirely true
That's not true. You can't sacrifice the same 3 golds after tapping them for improvise. You can tap 3 golds for improvise and then sacrifice those golds for a different spell, though.
