AI attacking and blocking Observations

I was kiling the creature with an instant.

I know Stuffy Doll has been reported before some times, but the AI still does not see any danger in it and keeps attacking when i have it in play. Damage will get through if there are more than 1 attacker, but when Stuffy Doll is enchanted with Pariah or equipped with Pariah's Shield the computer only kills itself by attacking.

Well the AI doesn't cheat and peak at your hand to determine the best plan of action, so considering that you would have died according to the availlable info, the all-out attack isn't too bad. The main issue here is that the AI attack code might be improved by checking for exalted cards then determine whether an all-out attack is better than a single attacker. I have a feeling it'll be a bit of a pain though because of all the layering in AI attck code.

The AI will attack into, or block, Stinkweed Imp without appearing to take its deathtouch-like ability into account.

I tried playing Stinkweed Imp and some deathtouch creatures in the same deck, and while the AI takes some pains to avoid running its creatures into deathtouch, it seems to treat the Imp the same as a vanilla 1/2.

The opponent attacked with a single Goblin Guide although I had Souls of the Faultless on the battlefield.

Amusing play by the AI: 1st turn Sacred Foundry, pay 2 life. Cast Children of Korlis. Sack it to gain 2 life.

ai had 7 lands(5 plains 2 swamp) and one 2/1 creature i have three 4/4 angel tokens on ai's turn it decides to cast oblivon ring for 3 mana on one of my angel tokens while it could have casted terminus for six mana from its hand to wipe the board clean

[Zirbert]

The AI had me down to 2 life, and had a Rhox in play. However, it held off on attacking one more time to finish me off, presumably because I had enough creatures on the board to (a) block all its atackers, and (b) counterattack for the win if the AI left itself open.

However, the Rhox damage-reassigning ability would have finished me off even if I blocked everything. I spent several turns at 2 life before building up a big enough creature army to attack the AI for the win.

AI can't block properly when I control Goblin War Drums or similar effects. For example, when AI is on 1 life and I attack with a 6/5, AI doesn't block with his 3 2/2 and dies.

[Milod]

have three 4/4 angel tokens on field, ai's turn with one 2/1 creature on field and casted a 2/2 creature after that it casted terminus. I think there must be done something to the priorty order

[Milod]

ai had 4 life left and has two 1/1 spirit(flying) tokens on field untapped and a 5/3 creature ,2/2 creature tapped and i got one 4/4 angels token on my turn untapped i used divine reckoning and the ai chooses the tapped 5/3 creature while it could have choosen the 1/1 spirit token to block my attack
not good move can there be somthing done about this?

Not until the AI looks into the future to determine the right play.

1.2.9 Beta -

The AI will attack with a Goblin Elite Infantry into a 1/2 blocker. I thought the AI took attacking / blocking triggers into account when evaluating combat options; this is definitely a suboptimal play when the trigger is taken into account.

The AI doesn't block a 1/2 with Goblin Elite Infantry, though, implying that the trigger check is working on defense.

All 3 fixed! Thanks Zirbert.

AI is on 9 Poison and attacks with his only creature even though I control a creature with Infect.

Had a funny game: I played lots of elves against artifacts. AI had Platinum Angel on the battlefield (equipped up to 10/7). What then happened: In every turn I attacked with everything (beating the AI down to -500 life) and the AI blocked some of my creatures. Because of the Platinum Angel it does not matter how much damage below zero the AI gets but instead of finishing me off in two rounds with the only flying and very tough creature on the battlefield, the AI never attacked.
Then I played Viridian Shaman and targetted Platinum Angel...

I've just improved AI's attack decisions by better predicting counterattacks. These situations should be handled better by the AI in the future. Thanks cc-drake and mark.

I don't know how well the AI predicts counterattacks, but it doesn't do too well with straight-up blocking, frequently dying to a Phyrexian Crusader despite having lots of artifact creatures. (I considered using Pestilent Souleater or Vector Asp, but that'd be taking candy from a baby.)

Not combat-related, but Emerald Medallion lets me cast face-down green creatures for .
