how can I determine if a card is standard, legacy, or expanded ? is there a way to do this without using the filter options in my collection?
These 3 formats are defined by the expansions that are legal in each of them at the moment. Standard always includes all the cards from a certain point on that's defined every year. Right now, the cutoff is at Sun and Moon Base Set, meaning that all the cards released in the SM Base Set and onward are valid for Standard, while everything else that's older than the final XY set (EVO) isn't playable in standard.
Expanded is always everything from the BW base set and onward. This cutoff doesn't seem to change, so the format only grows larger as new expansions are added.
Legacy includes all cards from the HGSS era and the BW era, so it only excludes the XY and SM sets. This doesn't seem to change from year to year.
Honestly though, it's just a matter of memory. As you play, you will begin remembering what card belongs where. Until then though, just use the filter. I'll save you some trouble and I'll help you memorize the formats better.
so lets start with "color" versus "black and white" pictures of cards when I expand the card info in a card description. what is the significance of either the in-color or the black and white picture?
in trading, where does a cards deck-type get shown? what is the significance of the 'star', 'diamond', 'square' or 'circle' (at bottom of trade view) when I view a trade ?
The cards in color are the ones you already own. The ones in black and white are cards you don't own any copies of.
I don't know what you mean by deck type (you meant the format, perhaps?), but the little black shapes on the corner of the card are its rarity. Circle is "common", diamond is "uncommon" and the star is "rare".
