"Leng Ling" Rating Score by にしん

It's a Union Monster, but it doesn't matter which monster you can equip, so it's highly versatile, but instead of having its "original" ATK become 1000, you can attack twice.
Since the ATK that changes is the "original" ATK, Dark Rebellion, which can absorb ATK after equipping this card, Crystal Wing, which increases the opponent's ATK during battle with advanced monsters, and Supreme King Dragon, Dark Rebellion, Lyrilusc, which absorbs all ATK during battle. If you use the effects of the independent type 《Supreme King Dragon Starving Venom》, etc., you can attack twice while leaving a practical RBI.
After that, you can equip Drill Vernical, 《Raging Flame Sprite》, 《Mucus Yolk》and use it to strengthen your RBI. On top of that, it's a direct attack x2, so it's a total of 3,000 damage from the turn you put it out, and it's very brutal, boosting his ATK to 3,000 at once. In addition, it gains destruction resistance up to 1 time due to the characteristics of the union, and if it is not disposed of by the next turn, it will be overkilled with a direct attack of 3000 + 4000.
On top of that, it's good at offense and defense, and there are various procurement methods such as searching with 《Sangan》or witch, and salvaging with 《Recurring Nightmare》.
