Aside from the fact that this is probably the most cataclysmic event the game has ever seen story-wise, it's also the first set in an extremely long time to introduce a new card type, as well as just generally being jam packed full of crazy legends, double sided cards, new mechanics, and more
Drown in Ichor isnt quite Doom Blade, but it kills a large chunk of creatures you care about and spots you some extra proliferate action
Please note that even if the item is authenticated, there may be minor white chips or scratches on the card and initial scratches on the case as well
It makes you feel more involved in whats going on in the world that is Magic
You do not need to stop buying and trading for cards
One solution would be to just discard the 72nd card from each sheet, which is the error card (I am assuming this is technically possible, it apparently worked for the blank 1st card on the Jungle uncommons sheet, but I cant say for sure if its possible to discard a card from the middle of the sheet)
