Magic Stone Research Institute
>>> Banish a magic stone. Put the top card of your magic stone deck into the field.
J/resonators you control gain [+200/+200] for each different name among all magic stones you control.
Rest a recovered J/ruler you control: Remove all cards in your opponent's graveyard from the game.
The Magic Stone Research Institute, founded by Elixir ages ago, still exists in this world, although it changed its shape.
