Question for the programmers

I'm wondering if it's possible to add a random occurrence to the quest mode. The idea would be for an AI opponent with a starting life total of at least mid-triple digits and a really big deck to challenge the user to a single game at various random points in the quest mode. The user would be forced to use a deck with all of his collected cards to that point with enough land added in to equal 1/3 to 2/5 of his card total.
