After a rotation or a new set, most Pokémon lists change by a handful of cards. Compare the old list with the new one and see exactly which Pokémon, Trainers and Energy changed.
Deck A
Deck B
A deck is 60 cards, with no more than four copies of any card other than basic Energy, so many changes are a count going up or down rather than a brand new card.
When a rotation takes older cards out of Standard, compare your last legal list with your new one: the removed cards are what rotated out, and the added cards are their replacements.
Moving to a newer printing of the same card is shown as a printing change, not as a new card, so your counts stay honest.
No. A quantity change is one row showing both counts, so the list of real additions stays short.
Yes. Basic and Special Energy are compared like any other card, so a change to your Energy count shows too.
Yes. Paste its Gradely deck link into either slot and it is found straight away.
