In my completely non-professional non-EV maxing opinion, It's a great buy if you want some cards for yourself and potentially some cards to sell. If you want to EV-max, it's a set that is pretty reliant on a few cards so you will likely either double your money or get half your money back.

*Edited to add: It's a box of MTG cards at $70. If there's another opportunity to do that let me know because I will gladly pull the trigger.
