If you like collecting treasure cards, this pack generally contains the best version of anything you can buy. Hit cards are typically 5% more accurate, pip costs are sometimes lower, and enchant values are sometimes higher. It is also one of the oldest card packs in the game. Since Wiz101 has come a long way since Eye of Bartleby was first introduced, I think it is time to add a few more cards to the pack.
Entangle (1-pip version)
Strangle (1-pip version)
Vaporize (1-pip version)
Unbalance (1-pip version)
If you remember, there were no individual Spirit school dispel cards until we reached Zafaria in 2012. I think we are at a place now where Eye of Bartleby can offer some 1-pip alternatives, just like it always has for Elemental school dispels (Quench, Melt, Dissipate).
