Level 12 LIGHT Dragon Fusion Effect Monster
ATK 4000
DEF 0
Materials: 7 “Crystal Beast” monsters
Must be Special Summoned by Fusion Summon or the following method, and cannot be Special Summoned by other ways.
・You can Special Summon this card from the Extra Deck by Tributing a Level 10 “Ultimate Crystal God” monster you control (You do not use “Polymerization”.)
(1): Once per turn: You can banish 1 “Crystal Beast” monster in your GY; this card gains ATK equal to the banished monster’s ATK until the end of this turn.
(2): (Quick Effect): You can Tribute this Fusion Summoned card; return all cards on the field to the Deck.
TL Note: The “Ultimate Crystal God” part of this card may seem confusing at first. In fact, both Rainbow Dragon and Rainbow Dark Dragon are considered “Ultimate Crystal God” monsters – that part of the name was dropped in the TCG versions of the cards. Certain cards actually ask for “Ultimate Crystal God” cards in the OCG versions of their text, such as Rainbow Gravity, but that was worked around by specifying the only two (at the time) “Ultimate Crystal God” monsters that existed. Note that Malefic Rainbow Dragon omits the “Ultimate Crystal God” part from the name, meaning it is NOT part of this theme unlike the other 3 Rainbow Dragons.
This card, however, throws a big, sparkly wrench into all that, hence our choice to include “Ultimate Crystal God” in the effect text translation.
