v1.0.3.2
Hey everyone, I’m back with another Deck Advisor update!
After fixing bugs related to the 9/4 Arena update, this week was mostly about improvements to the underlying algorithms rather than adding new features. Read more about the new changes below!
There is now a comprehensive User Guide (including Troubleshooting tips) available at the Daily Arena Deck Advisor Github Wiki.
Here are the features that have changed since the previous version:
The Replacement Suggestion algorithm got an upgrade in this release.
In addition to using the static card ranks when choosing between potential replacement suggestions, the program now also calculates “card association” statistics (for example, 25% of Standard decks that contain Spellkeeper Weird also contain Cloudkin Seer, so Cloudkin Seer gets a 0.25 bump in its static ranking when considering replacement candidates for Spellkeeper Weird), and uses those to influence the replacement suggestions.
The effect is subtle, but there does seem to be an improvement based on the testing I’ve done using my free account.
Here are some example differences:
For the Izzet Saheeli (Standard) deck, the following replacement suggestion:
2x Disdainful Stroke => Anticipate
became
2x Disdainful Stroke => Negate
Seems legitimate, as you’re now replacing a counterspell with a counterspell.
For the RDW (Arena Standard) deck, the following replacement suggestion
4x Calvalcade of Calamity => Lava Coil
became
3x Calvalcade of Calamity => Lightning Strike 1x Calvalcade of Calamity => Lava Coil
Basically, the algorithm now favors burn that can go to face, likely due to association with Chandra's Spitfire, which has high synergy with noncombat damage to the opponent.
For the Liliana, Dreadhorde General (Brawl) deck, the following replacement suggestion
1x Lilian's Triumph => Unlikely Aid
becomes
1x Lilian's Triumph => Bladebrand
This also makes sense, since the deck has graveyard and death trigger synergies and should generally prefer trading your creatures with opponent creatures (and getting an extra card draw!) over saving your creature (even if it means your creature eats theirs).
If you see replacement suggestions that have an obvious better option in your collection after the update, please contact me with the specific details and I can look into further improvements (there are more changes I can make, but each level of improvement requires successively more/harder work to implement). Feel free to open an issue over at the Daily Arena Deck Advisor Github issues page issues page and put the information in there to make sure it doesn’t get lost.
For Brawl decks, a new section was added to the deck details display that calls out the deck’s Commander, and also shows its color identity.
The Commander’s color identity is now used when computing card replacement suggestions for Brawl decks (in the previous version I noticed cases where there were some illegal suggestion such as Golos, Tireless Pilgrim in a deck with a mono-Black commander).
