I think Transmute Artifact is one of the most broken cards in Old School and it is very good in Vintage too but not played much lately. This card used to compliment the Tezzarator decks of old as another way to find the Time Vault or the Voltaic Key.
This card offers other flexibility with some reanimate spells. The tradeoff of trading an artifact then paying the cost will not get you a Blightsteel Colossus but it can get a Steel Hellkite or some other fun things.
The advantage of this card is that does not require a sacrifice until it resolves so counterspells do not hurt you in the same way that they do with Tinker. It is also unrestricted so running 2 or 3 can be very strategic.
Can we discuss strategies and deck to make this card playable in Vintage?
