Tôi kích hoạt hiệu ứng của Zoodiac Drident để phá hủy 1 lá bài ngửa trên sân, chọn mục tiêu vào True King Lithosagym, the Disaster trên sân của đối thủ. Nếu đối thủ của tôi xích Book of Moon và thay đổi True King Lithosagym, the Disaster thành Tư thế Phòng thủ ngửa, thì hiệu ứng của Zoodiac Drident thực thi như thế nào?

EARTH

4 Level 4 monsters Once per turn, you can also Xyz Summon "Zoodiac Drident" by using 1 "Zoodiac" monster you control with a different name as Xyz Material. (If you used an Xyz Monster, any Xyz Materials attached to it also become Xyz Materials on this card.) This card gains ATK and DEF equal to the ATK and DEF of all "Zoodiac" monsters attached to it as Materials. Once per turn, during either player's turn: You can detach 1 Xyz Material from this card, then target 1 face-up card on the field; destroy it.

EARTH 9

If this card is in your hand: You can destroy 2 other monsters in your hand and/or face-up field, including an EARTH monster, and if you do, Special Summon this card, and if you do that, and both destroyed monsters were EARTH, you can also look at your opponent's Extra Deck and banish up to 3 monsters from it with different names. If this card is destroyed by card effect: You can Special Summon 1 non-EARTH Wyrm monster from your GY. You can only use each effect of "True King Lithosagym, the Disaster" once per turn.

Spell Quick

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