Draft pick order

How is draft pick order for the AI determined?
By which I mean, I have noticed that cards have a 'Ranking' and that the AI picks low Rankings over high ones; but how are those values determined?
If it's done by committee, how would one get onto such a committee?

Low rankings are better than high ones. Because the numbers are derived from Card Rank Position / Set Size. The rankings are pulled from different websites that have real players run drafts to gather ranking data.

K, thx!
I ask because I'm often surprised by how consistently late I can get really powerful commons like Thrash of Raptors or Sure Strike in Ixalan, or Phantom Monster and Dragon Egg in Iconic Masters...

Like, seriously, tho, I shouldn't be getting a powerful colorless card like Pirate's Cutlass on pick 11. Is something wrong? Does Ixalan not have enough data for it?

XLN may not have had it's rankings updated since pre-release time. It's not an automated process as part of Forge's release.shteev wrote:Like, seriously, tho, I shouldn't be getting a powerful colorless card like Pirate's Cutlass on pick 11. Is something wrong?

Sorry to necro, but I added some custom cards to my cube and I'm having trouble getting the AI to pick them. In res\draft there are 3 ranking files, "cube_drafting_rankings" "cube_mtgo_rankings" and "rankings". How is it determined which file is used? Also, if I just put my custom cards at the top as #1 so I don't have to renumber everything, will that work?

Necroing is black magic, so, it's allowed, I think?
I can definately confirm that editing those ranking files has a huge effect on how Ai draws.
Once I inverted all rankings in that .txt-file for a specific set (LEB) and normal draft was like christmas on each pick, it was ridiculous
Like second to last draw Demonic Tutor ridiculous.
Your custom cards need to be added to the editions txt-file of the set you want them to appear in as well, I think.
A spreadsheet tool like Libre Calc/Excel helps quite a bit to sort/change rankings.
And you could always add a custom card to Ais hand using dev mode to see if it's chosen/played correctly.

Using a spreadsheet to edit it is definitely a good idea. Do you remember where you found the rankings for specific sets? The only rankings I can find are the 3 in the draft folder. Also, do I need to add my custom cards to a set for things to work properly?

Well, right where you found them already, I edited /res/draft/rankings.txt, #1 representing most valuable pick from that set.Nerdslayer wrote:Do you remember where you found the rankings for specific sets?
I think so, yes.Nerdslayer wrote: Also, do I need to add my custom cards to a set for things to work properly?
Experiment away

PS: Also I consider it a given that you have a functioning custom card, with a working ruleset and placed inside /res/cardsfolder into one of the alphabetical sub folders from the unpacked "cardsfolder.zip"?
