This is in a classification of cards that is very awkward. I classify this is “You’re going to lose a lot of games to this in Limited, hate it, and then literally no other format, not even EDH, will want it and you’ll forget its name in 4 months.” A lot of people lost a lot of games to Tromokratis in limited not too long ago. Do you know what that card does anymore without clicking to read it? Literally the only thing it does right now is sell for a dime.
Could casual and EDH decks run this? Eh. I can’t see anyone being overly excited about it. This is a bulk rare that will be very good in Limited, and as weird as that feels, that’s just what’s going to happen.
