The OCG keeps surprising us with the first batch of Korean premiere cards!
EDIT: ALL EFFECTS CONFIRMED
EARTH Level 3
When this card is sent to the graveyard: Draw 1 card, then return one card from your hand to the top of your deck.
DARK Level 3
Once per turn: You can change this card to face-down Defense Position. When this card is Flip Summoned: This card gains 800 ATK until the End Phase.
Outer God Nyarla
EARTH Rank 4
2 Level 4 Monsters
When this card is Xyz Summoned: You can discard any number of cards; increase this card’s Rank by 1 for each card discarded. Once per turn: You can target 1 monster in your Graveyard; detach all Xyz Materials from this card and attach that target to this card as an Xyz Material, and if you do, this card’s Type and Attribute become that Xyz Material’s original Type and Attribute.
Banish 1 EARTH, 1 WATER, 1 FIRE, and 1 WIND monster from your Graveyard; shuffle 1 card on the field into the Deck.
During this turn, apply these effects.
•Rank 3 or lower monsters on the field gain 500 ATK and DEF.
•Rank 4 or higher monsters on the field cannot attack.
And nothing of value was lost. Looks like mostly generic, seemingly splashable stuff tied to specific roles for certain archtypes.
Also, it appears that Korea did indeed replace its Ultimate Rares with Secret Rares.
