This has good potential. As a first go at this these cards are alright. Paizo should learn from all the other comments made about this deck and try again. I'll not reiterate the other complaints.
If the cards were not limited to single side only maybe some more information about buffs could be added. For example "Enlarge Person" doesn't mention CMB or CMB modifications, skill adjustments. Fighting Defensively or Total Defense makes no mention of a bonus if you have 3 ranks of Acrobatics. etc.
Another option for the flip side of cards could be De-Buff effects like Bane (printed opposite of Bless).
