how does teh difficulty ramp up? cheaper units at-factory? more HP/damage/etc for AI units?

as far as how to generate a deck for it...duplicate the "open a pack" bit, run it several times (more for higher difficulty) ..have several possible AI "strategies" like i suggested earlier (air, ground, rapid offense defensive, resource-oriented, CP oriented), rank cards on a 1-10 scale relative to each strategy...let it pick out several slots of units, then a few sots for things like heroes/buffs/heals.say, a 7/3 split, making choices based on the scale value of the cards for that strategy.
