Atraxa is the single most built deck on EDHrec I doubt she's unknown
Last I checked Muldrotha was highest, but I had indeed forgotten Atraxa was right up there - even if I meant moreso in the 'lore' sense than the played sense (referring to OG Teysa compared to something like Oona, not to Kaalia or Yuriko).
Worse comes to it, I throw Oona into my Yarok and/or Muldrotha deck I'm brewing, I suppose.
WotC has shown itself to be a pretty poor judge of what the EDH world needs.
A part of me still laughs when Gavin arguably overpromoted/promised good reprints in 2019, and/or when Wizard's solution to white's weakness is either 'everyone draws 1' or one-off cards like new Heliod happening to go infinite with walking ballista or triskelion. I'm glad we're getting commander legends, because not having at least a battlebond equivalent would have been rough.
Red has gotten a much arguably better bandage with cards like Dockside extortionist, Torban, and Embercleave, but even then I think it's still underrepresented - most non-cEDH mono-red decks I see (in my limited viewing, admittedly) are Krenko variants or OG Purphoros.
They could sell an Atraxa by itself for $30 at least. I wouldn't be surprised if they had a bunch of EDH-specific drops at some point. Fancy Atraxas, Yaroks, Sorin Markovs, and so on.
It's why I'm simultaneously very excited and kind of dreading Commander Legends.
Honestly, commander legends is why I think there won't be any significant 'high-demand' commander reprints in Secret Lairs - to the point where I'm mildly surprised we're seeing Meren. We'll probably see high-value and/or good commanders like Atraxa and other past commanders in the Legends set - I'd guess not 'all' of the past commanders will make it in, but several (probably excluding partners) will be included.
But on that note, I'm super, SUPER curious as to how they actually plan to make an official 'draft-viable' commander set - as 'official' drafts, in my (again, admittedly limited) experience have been way different from hand-picked commander cubes, which have a much 'bigger' selection of good/viable cards to throw in there and not have to worry about pack EV..
Presumably, there has to be a legend in every pack, similar to WotS' planeswalkers, but beyond that....I have no idea of how well Wizards is gonna pull this off.
