Once per turn (Quick Effect): You can detach 1 Xyz Material from this card; activate 1 of the following effects depending on the name of the Xyz Material you detached:
- "Oracle" - Send 1 monster from your Deck to the GY, and if you do, this card gains ATK and DEF equal to that monster's ATK and DEF respectively.
- "Archknight" - Send the top 3 cards of your Deck to the GY, then banish 1 card your opponent controls.
- "Astralstar" - "Solevias" monster you control cannot be destroyed or banished until the end of the turn.
- "Embodiment" - This turn, when you take battle damage from battles involving this card, inflict 3000 damage to your opponent.
- "Herald" - Negate the effect of all face-up monsters your opponent currently controls until the end of the turn.
- "Fated Warrior" - Target 1 "Solevias" Xyz Monster in your GY, except "Fated Warrior of the Solevias"; attach that target to this card as an Xyz Material.
You could consider it as the Xyz Counterpart of Sol Splendente; may not be so easy to pull out and its effectiveness really depends on the materials you chose, also it is really vulnerable when it is alone
