They always change the rarity of this card and never release it after that, happened multiple times in the past. Maybe this time will be released, just saying don't give your hopes up.
Yes and cyber dragon was relevant for so long it would be completely wrong if dark magician was not given support or limit list adjusted in some capacity. But you never know with komoney.
My best guess is we are getting 1 copy of Apprentice for free, like how we got Alternative before.
No idea about the next main box, but there might be another SD related to DM where there'll include DM the Dragon Knight and Eternal Soul. Along with a decent skill for DM.
Yea but I can’t search apprentice like kaiba can search alternative blue eyes on my first turn so no I demand that I can have 3 apprentice illusion magicians
