Tôi kích hoạt hiệu ứng đầu tiên của Fullmetalfoes Alkahest , chọn mục tiêu vào True King Bahrastos, the Fathomer trên sân đối thủ của tôi. Nếu Book of Moon là chain và Fullmetalfoes Alkahest được thay đổi thành Tư thế Phòng thủ hướng xuống, thì hiệu ứng của nó sẽ thực thi như thế nào?

FIRE 1

1 "Metalfoes" monster + 1 Normal Monster Must be Fusion Summoned. Once per turn, during your opponent's turn (Quick Effect): You can target 1 Effect Monster on the field; equip that target to this card. This card gains DEF equal to the combined original ATK of the monsters equipped to it by this effect. You can use monsters you control equipped to this card you control as material for the Fusion Summon of a "Metalfoes" Fusion Monster that lists them as materials.

Spell Quick

Target 1 face-up monster on the field; change that target to face-down Defense Position.

WATER 9

If this card is in your hand: You can destroy 2 other monsters in your hand and/or face-up on your field, including a WATER monster, and if you do, Special Summon this card, and if you do that, you can banish up to 2 Spell/Trap Cards from your opponent's field and/or Graveyard, if both the destroyed monsters were WATER. If this card is destroyed by card effect: You can Special Summon 1 non-WATER Wyrm-Type monster from your Deck in Defense Position. You can only use each effect of "True King Bahrastos, the Fathomer" once per turn.
