By that logic you can also say it's 'playable' in legacy, vintage, modern and standard.
Again, playability is super meta-dependent. I've seen EDH groups that have ultra-tuned decks that can win pretty quickly and consistently and I've seen EDH groups that have "throw everything in a pile and just have fun" decks. Likewise, there are plenty of people who play standard with subpar decks and do well, because everyone else in their meta is also using subpar decks. In competitive EDH (for lack of a better term) there are plenty of cards that are unplayable.
Uh, no. Unless you just take the weirdest possible interpretation, it does not follow. Yes, technically you can put anything into a legacy deck. But unless you're absolutely unaware of what the legacy format actually entails, there really shouldn't be any confusion between the different formats. Commander is a casual, non-officially sanctioned format that was created by fans, for fans. Again, it's not a knock on it. I have like, 8 different commander decks.
...and yes, if your local meta is 100 percent graveyard hate, then anything zombie may not be playable. Again, this is really a semantic argument of the worst kind. You know darn well the difference between a playable card and an unplayable one. Commander is factually, unequivocally the Magic format that allows for the greatest range of actually playable cards.
