AI attacking and blocking Observations

[Symphonic]

The AI never sacrifices any creatures to my attacking Desecration Demon, even if it is going to die that turn because of not having any creatures with flying that can block. (In my case it had a creature with flying, but with a unleash counter on it, and it just lost the game instead of sacrificing the creature)

[Bordergeist]

Not sure if this is the right thread, or if it's been commented on before, but the AI is really bad at playing against Annihilator--it invariably sacs lands last, meaning there are lots are times where it sacs creatures that would be sufficient to kill the attacking Eldrazi, thus losing some games it could have otherwise won.

AI has two Savannah Lions and a sick Flinthoof Boar (but with red mana available). No cards in hand. 17 life.

I have 4 untapped lands but no creatures. One of the untapped lands is a Keldon Megaliths. I also have a tapped Lumbering Falls (which could be activated but can't actually block since it's already tapped). I'm at 6 life with 1 card in hand.

I think the AI is worried about the activation + block from my manland, but it's not actually possible. Either way an all out attack would cripple me pretty majorly

AI attacks with Child of Thorns or Llanowar Augur or Bloodthrone Vampire alone while having no other creatures, even if my creatures are stronger.

in case of Bloodthrone Vampire, even if it has other creatures it does attack me, but didn't use the effect to make the Vampire stronger than my creature.

hello all, in the latest version of Forge (snapshot 30954) when attackin with Hero of Bladehold I notice 2 things :
1: I don't get to choose which action to take first (having the Soldier Token or having the Battle Cry)
2: I don't get the tokens either from Hero of Bladehold or the Turntimber Ranger




Also the stack isn't resolved when I pass phases


can this be looked at ?
thank you.

The AI has several quirks with attacking/blocking that probably just has to do with the algorithm but I'll put down my observations anyway. I'm presenting simple examples of the phenomenon I see so they exact examples might not work 100% of the time but I'm pretty sure they will.

The AI doesn't look for trades when facing lethal damage. Take the following example. I have two 3/3s attacking the AI who is at 6. If they have two 2/2s out they will block one 2/2 on each 3/3, instead of double blocking a 3/3 and going to 3. This gets worse the more creatures both players have which often turns close games into unwinnable for the AI.

The AI loves to attack into no blockers even when trading damage disproportionately. Take the following example. I have a 3/2 in play. The AI has a 1/4 creature in play. If my 3/2 is tapped the AI will attack.

The AI will attack into low power creatures even if the creature doesn't die. The AI will always attack a 2/2 into a 0/4 if there aren't any other creatures on the battlefield. I think they will do this even into something like a 1/4 or 1/4 vigilance but I'm less sure of that.

The AI will use pump spells to get damage in. If I have a tapped 2/2 on the battlefield and the AI has an untapped 2/2 with a giant growth in hand, they will attack and use the giant growth to deal 5 instead of blocking and trading the trick for the creature.

hello all, with snapshot 31013, in a commander game, manythings didn't happened in this round :
1: No token from Armada Wurm
2: With Trostani in play, no gain of life from casting the Wurm and since no Token, no life there either.
3: Stack dosent't empty from phase to phase.


thank you.

AI should never ever block with Platinum Angel, even if my creature is weaker because i can still pump it up.

I have Dwarven Warriors and Granite Gargoyle. The AI has Orcish Artillery. I'm at 2, the AI is at 3. The AI has no cards in hand. It attacks with the Orcish Artillery, which I can freely block, and then it is dead on board.

[Xyx]

Once I'm at really low life and the AI smells blood, it will start making really terrible attacks where I get profitable blocks. Almost as if it hopes I'll misclick and not block its 1/1 with my 1/4.

AI keeps making meaningless attacks into my Yotian Soldier. Trying to bluff a combat trick is one thing (even while it's tapped out), but it leaves itself open to the backswing of the soldiers for no value.

Hi, the IA put into the battlefield Viashino Sandstalker, then the IA place attach an aura(Ordeal of Purphoros) and IA not attack this turn, at the end of the turn viashino Sandstalker turn back and the aura goes to the graveyard.
PD:sory for my bad english.

[Hanmac]

@masterdark1905: your problem should be fixed with r31177


r31195:

dump blocking sometimes, i noticed this situation:
Me 4 LP, one 4/4 creature
AI 5 LP, one 0/3 creature and one 4/4 creature

i does attack with my 4/4 creature and the AI does block it with his and does destroy both.
he shouldn't do that, he should block with this 0/3 so he can attack me with his 4/4 creature.

and yeah i did win against the AI in this round.

[Xyx]

I keep noticing that the AI gets really suicidal once it presents lethal. It'll just run its 2/2s into my 4/4s. Maybe it hopes I won't block because I fear a combat trick... but it's lethal, so I'm blocking.

AI attacks its Fallen Angel into my two Azure Drakes. It has some random 1/1s to sac, but it just lets the angel die for nothing.
