As Ary pointed out, these are the current (or were current) items that the simulator will accept including a seed http://magicduel.invisionzone.com/topic/16600-the-big-combat-bugfix-more-information/?p=165630 The simulator will be more useful as I will store all inputs to the simulator, and then output, and from this the simulator can be rerun with different levels of logging, or ran through step by step to see precisely what it is doing.
Since all the inputs will be stored, they wont be depdendant on things that change and become impossible to reattain (aka wins, effects, stats at the time, etc etc) which is the current problem with combat.
