I'm trying to hack this game using charles because almost all of it is server sided.

So I've determined that the store/purchases and the energy/gold are all server-side. The only thing the game 'requests' outside of battles is a UserID and some other basic information. Nothing to hack here.

However, inside of battle there are a few things that seem to be client side including the HP & Attack as well as the set of cards in your hand. I tried editing some breakpoints on card hands which ended up playing some of my opponents cards that attacked me and I promptly lost lol

I'm wondering if anyone has used Charles to hack this particular game http://www.kongregate.com/games/synapticon/spellstone

If not, are there any guides on hacking server-side card style games with Charles? I'm kinda at the limit of my knowledge here
