The card finally has a clear resolution, so we can finally confirm its effects!

Ryuusei Houkaiki Dusa / Dusa, the Meteoric {Houkai} Vessel

Light Machine / Effect

LV4 1600/1600

(1) If this card is Normal or Special Summoned: You can send 1 “{Houkai}” card from your Deck to the Graveyard.

(2) Once per turn, during either player’s turn, if a monster(s) was sent to your Graveyard during this turn while this card was face-up: You can activate this effect; this card gains 200 ATK for each monster with a different name in your Graveyard, until the end of this turn.

We’re still waiting on the rest of the Archetype and details about the movie to be revealed before making a decision on the name.
