First I was about opening a new topic, but I found this.
I also have an Idea for AI7.
I think the hp, cards, draws per turn and so on of AI7 should be enormously raised and each of this "improved FG´s" should have all kiinds of cards.(perm, creature control etc.)
The AI7 should be really tough.
To be able to defeat such an opponent I thought:
Why not make it 2 VS 1, so that you are able to invite a friend or play with a random player together.
Card effects and so on are for both (maybe)except shields. They have shared HP of maybe 200 and the AI7 attacks (maybe,because maybe separate shields) alternate. With shared hp they wont die separately.
If you deck out, you will draw from your allies deck maybe.
But the rules doesnt really matter if nobody likes the idea, what do you think about 2 vs AI7?
The only problem would be, that you not only need to develop the new AI7 but also a new "fightsystem" or rather an improvement to 2vs1. But if you do you will also open a way for 2vs2 pvp.
OK, I just looked... and I found the idea for 2vs2 was already there:

I hope my idea wasnt already mentioned anywhere too, but at least I didnt find anything with advanced search.
