It creates Treasure tokens, a mana that is wildly flexible and will stick around for as long as we need it to (or until it gets turned off by a Collector Ouphe)
This six-CMC artifact can be tapped for another 6 mana and you get to go through your library, exile as many artifacts as you like and make that many 1/1 Myr artifact creature tokens
I have no fully confirmed truth about a lot of these things, only a "best bet", and every now and then some new info about pre-Alpha playtest cards comes out and turn things on its head
Doctor Who and Magic: The Gathering are proving to be an exceptional match
though some commanders like Faldorn, Dread Wolf Herald use discarding as part of the cost, the card itself doesnt care about discarding
