I've gone ahead and added the Phoenix Saga set block to the plugin. In addition, all year 5 promos and cards till DMC-35 have been added. This block consists of the following sets: (Set 18 is skipped due to being a reprint set)
DM-19: Spectacle Nova DM-20: The Ultimate Nova DM-21: History of Devil Nova DM-22: The Dragonic Nova DM-23: The End of the Universe
As the name suggests, this block contains a large number of Phoenix cards with corresponding support. Also, a large number of new races have been introduced. Particularly, shared Races among multiple civilizations. The focus is on race-based strategies.
Lore-wise, the story takes place 10,000 years after the end of cross gear set block. Most old races are now extinct and now each civilization is ruled by new races; Grand Devils, Tyranno Drakes, Dreammates, Great Mechas and Arc Seraphims. Powerful Phoenixes have also appeared.
