my deck includes the following sources of domain: 1x astridian diplomat, 1x grove, 1x bone fortress, 1x altar of ix. I am playing a game and the sources have been cast. diplomat, fortress, and grove are destroyed, leaving me with 1DL for domain. I am holding 3 cards including lysis. I expect to autodraw a grove. I don't.

I have seen similar behavior in sealed with other domains not auto-drawing as I would expect.

I've encountered similar behaviour.
I'm on 2 (or even 1) domain with no more domain sources in the deck, I have 3-domain cards in hand, and I don't draw a Magma Chamber from outside the deck.

The funny thing is that I usually do eventually draw one - after a few turns. I haven't been able to determine what causes it to finally be drawn.

Could it be that you don't autodraw it until you have a card that actually requires Sylvan domain in hand (rather than one that requires DL+X domain)?

If you need X domain autodraw gives you any fated card that you can cast.
If you had problems or some case that confused you give me an example and I'll explain what should happen.

no, it doesn't. see my example above. or yaron's. autodraw has been broken since the day it was created. and I continue to both win and lose games because of it. most recent example was two days ago.

most of the bugs hurt you; however, for those who wish to abuse, I would recommend decks with 2x vapor mahal -- you will always autodraw the second immediately after casting the first. even if you are at two domain and have no three domain cards in your deck.

Autodraw was fixed 9 days ago. You probably missed that.
If you still saying that you had problem with it please describe your case.

I tested many different cases of autodraw after fixed that, also I knew why autodraw was giving that basic building after several rounds.

no, I didn't miss that. and people have complained about losing because of broken autodraw since then. if you want a specific example, see my post above?

All cases above works fine. Without bugs.There was no forum posts about autodraw since I told that it's fixed and I haven't heard about it in game. So please give me an example that doesn't work, examples above works fine.
I'm not saying that there's definetly no bugs, I'm saying that all known cases was fixed.

first, let me note that there is nowhere obvious that the current autodraw rules are stated ... so, apologies if I am missing the point of autodraw. however, I note that I am not alone in missing the point.

to the best of my understanding, autodraw fails in the following cases:

1) 1 grove in deck. 2 mahals in deck. both mahals will be autodrawn (if not already in hand) starting on round two -- even in no three domain cards are in hand. wait, it gets worse. both mahals will be autodrawn even if there are no three domain cards in the deck. wait, it gets worse. both mahals will be autodrawn even if the deck is ENTIRELY ONE DOMAIN SYLVAN (plus two vapor mahals).

2) alabaster pantheon: same problem.

3) astridian diplomat: same problem (I was too lazy to reproduce this one tonight. if you fix the other two and think this one is fine, I'll check it again.)

4) 2x mahal in deck. 1x hall in deck. hall has been destroyed. 1 mahal in play. cards in hand require 1MF or 1EL or 1MF/1UA or 1EL/1UA. hall is needed. mahal is autodrawn.

5) I believe case four happens even with two basics (as opposed to a basic and a mahal). too lazy to verify this right now -- once again, if the above issues are fixed and this is not, I will try to reproduce.

So cases 1-3 is part of autodraw. Also I reproduced cases 4 and 5 and going to fix that.

Thank you.
