Ra gets new fodder, and a new monster is a reward.
Yami Marik gains access to a new skill to support The Winged Dragon of Ra:
生贄を束ねる力 Ikenie wo Tabaneru Chikara (Tribute-Tied Power)
(English Version Name Subject to Change)
The ATK and DEF of “The Winged Dragon of Ra” will be equal to the combined ATK and DEF of the monsters used to Tribute Summon it.
Granadora will be a new card to collect from Yami Marik.
