there are decks that should fight hard for board control. e.g. zoo.
how do we config VAI to aim to clear opponent's board relentlessly? or can we?

my initial guess is tuning values in GlobalValues.json,

the guide only suggested "aggro deck, bot can only uses first turn's value...". config for control behavior was not mentioned and I wonder if the community is missing the opportunity there.

Thanks for input spy.
I can see that setting json for board clear is a good idea. The catch is a few decks don't run board clear spell, but relies on minion to control the board. e.g. recruit/mid-murloc paladin, zoo, token evolve shaman, etc. In those cases, I feel like we would need to tune the (global) values and encourage the AI to trade minions.

Sure. It is doing quite well in many cases even.
But let's say we are to encourage VAI to trade minion more often, what (global) value(s) we may tune, in what direction and what range. Any hint?

The same can be said to other playstyle.
Seeing that even scottbreak and botwhat use pretty much the same global values for every deck they share, I honestly believe the bot have potential there, waiting to be untapped by the informed.
