They just did reprint reserved list cards in mtg 30th. Revised dual lands did take a significant hit to price. If anything I saw more people buying revised duals because of this.
Yea I don’t buy the “reprinting the reserved list will crash everything to 0”. Many old cards hold their value even after they are reprinted. Anything originally printed in 1993/1994 holds tremendously more value than reprints: see anything from legends, arabian nights, alpha, beta, unlimited, antiquities.
Yes maybe original revised dual lands go down to $100 if they are reprinted, but they are definitely not going to be $5.
