This makes this card a good, if slower, way to close a game
At this point, they're still pretty minor characters, and this was back in the day where we made a lot less legendary creatures, so we never really considered making cards out of them at the time
Magician of Chaos This monster destroys 1 card on the field when the effect of a Spell or Trap Card is activated
(This is treated as a Fusion Summon with "Fossil Fusion".) During your Main Phase, except the turn this card was sent to the GY: You can banish this card and 1 "Fossil" Fusion Monster from your GY, then target 1 "Fossil" Fusion Monster in your GY
However, it prevents Extra Deck summons for the rest of the turn
This is the only meaningful change though
