I'm a little confused with the formats since I haven't joined any competitive TCG matches ever since I came back to TCG. In Standard, there are sets that are rotated right? But what if I have a card from an older set but was reprinted in a set that's currently in standard? Can I use that card in Standard?
For example, I have an XY base Xerneas. It's the same card but with different art from the STS Xerneas. Will I be able to use that card in place of the one from STS? Or should I need to have the proper card from the set currently in Standard rotation?
