Dragon J/resonators you control gain [+200/+200].

If a Dragon source you control or an addition you control named "Realm of the Dragon King" would deal damage to a resonator your opponent controls, it may deal that much damage to your opponent and each J/resonator they control instead. Apply this effect only once per turn and only if you control two or more magic stones named "Milest, the Ghostly Flame Stone".

Enter ⇒ If you control a J/ruler named "Falltgold, the Dragoon" or "Bahamut, the Dragon King", you may search your deck for a card named "Realm of the Dragon King" and put it into the field. If you do, shuffle your deck.
