I don't understand exactly what cards are legal in standard. I know that the most recent two blocks are legal but why is it that some cards from odyssey are still legal too?
Just cards that may have been reprinted. There is a stickied post called "standard format deck construction". That tells you what sets are legal.
ohhh ok I get it. I think what I was confused about, is that people link the older version of the card and not the reprinted version.
