REDD is very late, no use anymore.
Hoping atticus comes with great red-eyes skills (differently from joey dsod) and a few of missing red-eyes cards like alternative or a new fusion
Even if he doesn't come with good red-eyes support chances are they could add some in a box to go along with his release like they have done with other characters. So if you want red-eyes support survey for Atticus.
This hype about atticus comes from all the kids that grew up in GX era. True og funs support the real red eyes master. Joey Wheeler. Really stupid idea of Konami making another character with such an iconic card of Joey.
Well just like kaiba's random blue eyes, yugi's random dark magician etc. Those characters came during the first era where "deck support cards" were almost unknown, and were more type/attribute support cards. Despite that, Joey used red eyes metal dragon, dragon nails, b skull dragon, re black dragon sword, lord of red etc. He had many support cards.
"red eyes metal dragon, dragon nails, b skull dragon, re black dragon sword, lord of red". None if them are actual red-eyes support. They are generic and lord of the red cannot even be ritual summoned with a red eyes alone, its a lv 8
Even if you don't count REBMD, B Skull & REB Dragon Sword as RE support, they ARE related to the archetype.
Dragon Nails was never an actual card, no arguments on that.
Lord of the Red's ritual spell is Red-Eyes Transmigration. The ritual spell directly received support from RE cards and also it can use RE monster from grave for its ritual summon. Indirectly, Lord of the Red is related to RE.
Lord of the Red not being summonable with REBD alone actually makes sense if you consider it, lore-wise, as REBD merging with Joey. The additional 1 level comes from Joey.
