Those Who Assaulted Yomidgard (MP03-071 XR) [Masterpiece Collection 03 "Dimensional Hope"]

[Extension Rule] You can start the game with this card in your extension rule area if your starting ruler was released in Assault of the Demonic World (ADW), and you have five cards with an"Amadeus' Purity" ability in your deck, and three among them share an attribute with your starting ruler. If your opponent doesn't control a card named "Those Who Assaulted Yomidgard" in their extension rule area, and players would choose who plays first, you choose that player instead. After you mulligan, expel up to two cards from your hand and draw that many cards. 4: Put a ruler you own released in Assault of the Demonic World (ADW) from outside the game into your ruler area and perform its judgment process. You pay less to play this ability, where X is the number of magic stones you control. Players cannot chase to this ability. Play this ability only twice per game.
