As the draft progresses, the relative importance of each Arguer changes. For example Signal is very important Pack 1, Pick 2 but slowly diminishes over the course of the first half of the pack until it is no longer relevant. The graph below shows how Arguer Importance changes over the course of a typical 3 pack, 15 pick draft.
For each card in a pack, each relevant arguer will analyse it and provide a strength score to a governing party - The King, who will rationalise all of the arguments into a pick.
You can interrogate the decision process for any given pick on the Draft Bot Reasoning page when you have a draft running. To access that page, simply click on one of the Castle drafters on the draft table plan.
You will see a table like this.
You can see that for each card in a pack, each Arguer has made an argument. The number inside square brackets shows the importance of the Arguer for this particular pick. A more important Arguer will have more say in the final decision. The colour of the light shows you how strong their argument is. Bright green being a Very Strong argument, and bright red being Very Weak.
A light with no colour means that the Arguer does not favour this card at all.
In the above example Liliana of the Veil was chosen, because she fits our Strategy, has Synergy with our previous picks, is a high Quality card and because black has a decent Signal.
Every now and then you will see an extra item of reasoning pop up in the table.
This indicates some sort of special circumstance, or additional information that the bot will consider when reviewing this card.

There are a lot of cards and strategies in Magic: The Gathering! Castle AI has been written in such a way that it's principles can be generally applied to most situations, but more importantly that it can be easily extended. If you feel that a pick violates general principles of good drafting then you can report it. Some things to consider before doing so:
To see picks that have been reported by others, head over to the Pick Decision Reports page. Anyone can vote on whether a pick report makes sense or not, and we will work on tackling the "most voted for" issues.
