"Dragon Ravine" Rating Score by ブルーバード

Broken. A trailblazer who transformed Field Spell from a mere backdrop into a factory-like role. It's like an industrial revolution.
With the existence of this card, 《Cards of Consonance》and 《Trade-In》can be used as much as you want. If you search the Dragunity tuner, you will get harmony, and if you do 《The White Stone of Legend》to GY and search for Blue-Eyed, or 《Eclipse Wyvern》to GY and do a pseudo-search for star 8, the train will be confirmed.
Easy to use for one kill. Toradora will appear just by searching the Dragunity tuner and matching it with a high-level Dragon in your field. Since the valley is a Field Spell, it can be used as a Toradora cost, and it is terrible that at least two attacks are confirmed.
And with the appearance of Dragon Ruler, the tag is completely off. For a Dragon Ruler with a GY effect, even the hand cost was almost intact, and since it could have been used as a trigger for 《Super Rejuvenation》or Eclipse, it was even Welcome. Dragon Ruler has strong individual power, but the initial movement such as valley and mausoleum was tremendously strong.
Even now, he is not satisfied with Dragunity, and Field Spell from the face of his parents who are disappointed with Dragon Link and Dark Wurm. Now it even works for searches, and its strength knows no bounds. However, a natural enemy called Urara appeared and I couldn't be happy without letting go.
