Looking for a Card battle system

Ok So I want to make a game that is essentially a D&D style table top game, now I figured I could use Lecodes tactical Battle engine for the actual nitty gritty, part but What I am really looking for is a Card equipment system. (Kinda like Guild of Dungeoneers.

I am looking for something that allows Items Characters & equipment to be in Card form and you add them to your Deck. You would get booster packs from the shop and inside 3 to 5 cards ranging from characters to equipment,

from there you can customize your deck adding characters and what not. by adding them to the deck it would unlock the certain weapon character or skill to be used in battle. Now i believe I could do this through extensive eventing (except maybe characters in the case of pulling doubles of the same character) but I was wondering if there is already something out there or if someone is already working on something similar.

I don't see how this would be too difficult with eventing. You can have the booster pack call a common event when used which would randomize a variable and give a different item based on the variable.
For duplicate characters, SRD has a Copy Actors plugin that allows you to have duplicates of the same character.
