Advanced Technologies Common & Rare Sheet
The Advanced Technologies Rare sheet had two copies of each of the 48 Rare cards plus four copies of the Common card. Due to the ratio of Uncommon sheets to Rare sheets printed the Common card shows up slightly more often than any given Uncommon card, but because it was printed on the Rare sheet it shows up in a Rare slot in booster packs, effectively replacing a Rare card.
Note that the depicted Print Sheets are just example layouts. I don't know what the actual card layout of these sheets were. In fact, the actual layout was likely more randomized to make it easier to pack boosters.
