For every lore thats lost, you get to draw a card into your hand
That's just speculation, of course, as WOTC could also decide to focus on interpretations of Marvel's comics more than the movie recreations - The Lord of the Rings products are entirely new imaginings of those stories and characters, for example, rather than following the lead of Peter Jackson's popular trilogy
One of those cards goes into your hand, while the other goes into the graveyard
Look for a small stamp on the lower left of the card art box that reads "Edition 1." First edition cards also lack the drop shadow around the card image, a detail that makes them "shadowless," which is a separate but related distinction
Abilities that apply "as [this creature] enters the battlefield," such as choosing a color with Diamond Knight, are also unaffected
For 4 mana you could be casting two Meddling Mages instead and get the full value of shutting down whatever your opponent is doing
