Should you control a Red Dragon Archfiend, or Synchro monster that mentions it, this card allows you to destroy one card on the field, and its entirely your choice on what you choose to destroy
My guess is that there are at least a couple hundred copies of Serras Sanctum for every Transmute Artifact that still exists
Plus, when your opponent Special Summons after theyve active 4 or more monster effects during a turn, Volcano can faux-Synchro Summon a Jurrac Meteor straight out of the Extra Deck to destroy the whole field
This is a deep set, so we'll be coming back to this again over the next few weeks
in the end, you can always change things around, so have fun experimenting
Also, many cards portraying events of the past were marked as "Flashback" cards
