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)
There are ways to increase the difficulty of the game, so theres plenty of replayability
Bygone Colossus
Older cards are much harder to get in normal packs because most places only have the more recent sets of MTG in stock
The Strixhaven Bundle contains ten Strixhaven Draft Booster Packs, two land packs with forty basic lands from the Strixhaven setting (20 in foil and 20 nonfoil), 1 foil alt-art promo card, 1 oversized Spindown life counter, 1 card storage box, and 2 reference cards
After all, in Magic , there are plenty of decks that can win
