If cards didnt have a set weight, even for foil versions, then it would be far too easy to fake rare cards for a profit.
The Grading Comparison Between Pokmon Cards I happen to have two (2) cards that graded the same between CGC and PSA
However, lets say you have a card that has some damage and youre guessing it gets a 7 because of a small indent but you see that the holo is perfect, no scratches, corners/centering are great, etc
When you do, cast it for its madness cost or put it into your graveyard.) Losing or gaining first strike after first-strike damage has been dealt won't cause a creature to deal combat damage twice or to not deal combat damage
Get one into your graveyard somehow (Prying Eyes below would work), and then use one on the other, get three free copies of it, then use them on other instants or sorcery cards in a graveyard for a grand total of, unless my math is awful, fourteen spell triggers
