The Extra Ones Are Dragons, You Say It's a Hero Deck?

(The composition of the duel in this article is more OCG, but there are unlimited extras. There will be some Asahi version characters and comic characters, and there will be more changes.) When traveling through DM, there is only a pair of incomplete elemental heroes, but the reinforcements given by the system are not right. Can you explain what the stage suitable for hero battles is called [Original Stone Royal Vein], is this okay?
