I'm just starting out and trying to make sure the _mulligan and _combo files I've created are properly being used by my bot using the default routine. Which file do I need to edit to make sure the proper files are being read and used? Thanks in advance!
When the bot is in the process of doing the mulligan, in the log you should see something like [Mulligan] EX1_287 should be mulliganed because it matches the user's mulligan rule: [card.Entity.Cost >= 3 and card.Entity.Id != "AT_079"] (True). which should match a rule in your _mulligan. For _combo, I do not know.
When you open the bot there are many initializing lines in the bottom half of the bot window. You have to scroll up and look for the lines "reading combo" and "reading mulligan". After the bot has read your mulligan file it should say something like "x rules loaded successfully". If there are less rules loaded successfully than in your mulligan file then you have errors in it.
