5 out of 5 rating for Spellbook Cards
These cards are not collectible cards. They are not covered in unique and evocative artwork. They are a tool for spellcasting classes to manage their spells and as a handy reference at the game table. As has been stated elsewhere, they are not meant to replace the PHB. The cards are heavy, laminated (so you can write on them with erasable marker). There a few things I do not like, I do not like the hard pointed edges (should have been rounded to maximize durability) and the fact that some cards were not printed with the 'Concentration' tag on them. I did contact at GF9 rep who appologized and assured me that they are working on fixing this issue in the upcomming print run. Nevertheless, they are very sturdy, laminated and handy. I highly recommend them for spell casting classes but remember, these cards are brief references, you still need to have the PHB handy for full text reference.
edit:
I am upgrading the rating since the makers at Gf9 have taken my feedback and that of many others and made necessary improvements on the cards, which will now contain the 'C' tag and rounded corners as well as other edits.
edit 5/21/15:
Yesterday I stoped by my FLGS and picked up all the new decks. GF9 has re-released these cards, the edges are now rounded, the text in some cards has been corrected, and a couple of cards that were missing have been added. Best part is that the 'concentration' tag that was missing is now included in the spell description. Excellent quality, and you can still write on them with a dry erase marker.
