AI attacking and blocking Observations

[Fizanko]

I thought when 2 legendary of same name entered the battlefield, both were removed ?
I didn't had any centaur token.

edit : looked at google and it seems there was a change to legendary rule

704.5k If a player controls two or more legendary permanents with the same name, that player chooses one of them, and the rest are put into their owners’ graveyards. This is called the “legend rule.”

So i assume it's not working with that latest change in Forge in the case of those 2 centaur tokens, because the game automatically got rid of both of them instead of only one.

edit 2 : the new rule was added at the time of Magic 2014

The AI seemed to block incorrectly in this scenario (causing him to die) instead of blocking in a way that would have allowed him to survive. I didn't check his hand, but he never played a combat trick and neither did I.

Here's the scenario:
During my Main Phase, I activated Garruk's ultimate, granting all my creatures +3/+3 and trample.

I attacked with a 4/4 Gorilla Shaman, 3/4 Plant token, 10/11 Tuskguard Captain, 11/11 Wolfie Silverheart.

AI is at 12 life. The AI blocked:
4/4 Shaman => 7/7 Spellbreaker Behemoth
3/4 Plant => 9/8 Woolly Thoctar
10/11 Captain => 2/2 Drumhunter
11/11 Silverheart = > 1/1 Druid of the Anima

Trampling 18 damage and killing him.

While it wouldn't have been pretty if he blocks:
4/4 Shaman => 2/2 Drumhunter
3/4 Plant => 1/1 Druid of the Anima
10/11 Captain => 7/7 Spellbreaker Behemoth
11/11 Silverheart = > 9/8 Woolly Thoctar (optimally double blocks the Drumhunter here, since everything has trample anyway and killing the biggest creature while absorbing the same damage is a smart decision)

If the AI blocks this way, there's only 10 trample damage instead of 16. Leaving him alive at 2.

The AI should be much more aggressive attacking with creatures generated with Flameshadow Conjuring. I haven't seen him attack once with them.

It seems AI does not count the "shade abilities" (B: creature gets +1/+1)
AI has 7 life and has only River Boa on the BF
Human has 17 life and Nip Gwyllion *2 and Wicked Akuba on the BF with 4 Swamps

AI's turn: River Boa attacks, deals 2 damage to human and ends the turn
Human's turn: Human attacks with 3 creatures and deals 4 damage, then activates Wicked Akuba's ability and wins.

[GangrN]

AI has one tapped River Boa on the battlefield.
On his turn, Human plays Vicious Hunger on River Boa.
Rather than simply regenerate River Boa, AI plays Stonewood Invocation on it.

[GangrN]

Again, AI does not take "shade ability" into account.

AI has 5 life.
Human attacks with Fallen Askari enchanted by Shade's Form and Vampire Lacerator. Humans has 8 untapped Swamps.
AI plays Reach of Branches and blocks Vampire Lacerator.

[GangrN]

Ogre Marauder:
Human attacks with Ogre Marauder, Ogre Marauder, Fledgling Djinn.
AI defends with Sundering Titan, Spire Golem, Lodestone Golem, Solemn Simulacrum.
AI has 4 life, Human 14.
AI fails to sacrifice Solemn Simulacrum to block one Ogre and blocks only Fledgling Djinn with Spire Golem (if it would sacrifice Solemn Simulacrum, it could block one Ogre in addition to Fledgling Djinn; it would have one life left and could attack on next turn with all remaining creatures for 14 damage)

AI doesn't seem to actually attack with creatures it returns with Puppeteer Clique (Maybe because the "exile at EOT effect" isn't actually on the creature?

Enemy does attack with a */1 Creature while i have Ashmouth Hound on the field ...
a dump move imo

[shteev]

AI attacked with Cave Tiger, Cave Tiger, and Argothian Swine.

I prevented the damage from all 3 with Rune of Protection: Green

AI then cast Symbiosis on two of these creatures (had the damage not been prevented, it would have been lethal).

Hello all, I attack with Drove of Elves (8/8) and Wilt Leaf Cavaliers (3/4) AI blocks the Drove with Birds of Paradise and double block my Cavaliers...

I think I would have blocked the Drove with sufficent creatures to destroy it (3 Beast) and blocked the Cavaliers with Ranger of Eos and Llanowar Elves



It's just my own 2 cents

[shteev]

I attack with Vigilant Drake. I also have Field Surgeon and Sanctum Custodian in play.

AI has Voice of Grace, Weatherseed Faeries, and Sanctum Custodian.

AI blocks with Voice of Grace and Weatherseed Faeries, prevents damage to Voice of Grace, and Weatherseed Faeries dies. I prevent damage to Vigilant Drake so it doesn't die.

AI should be able to see that my Vigilant Drake will not die because of my damage prevention; and therefore a better block is to block with just Voice of Grace, and prevent 2 damage to it, so it loses no creatures.

[shteev]

AI had a Worship in play, but blocked with a creature rather than taking 'lethal' damage.

[shteev]

I'm attacking with Gorilla Chieftain; AI blocks with Horned Turtle and Giant Octopus. I regenerate the Chieftain and kill the Octopus.

Next turn, AI blocks with Horned Turtle and Coral Merfolk. I regenerate the Chieftain and kill the Merfolk.

AI would be better off not trying to kill my regenerator whilst I have the mana up to be able to activate it, and just block with Horned Turtle on both turns, thus not losing any creatures.

-AI shouldn't harm its own creatures by attacking me with a single creature if I have a creature with wither and a Mother of Runes on the board.

Hello all, I attack with Drove of Elves (8/8) and Wilt Leaf Cavaliers (3/4) AI blocks the Drove with Birds of Paradise and double block my Cavaliers...

I think I would have blocked the Drove with sufficent creatures to destroy it (3 Beast) and blocked the Cavaliers with Ranger of Eos and Llanowar Elves

You shouldn't have blocked the Cavaliers with both the Ranger and Llanowar Elves as this would have destroyed both. Blocking the Cavaliers with the Ranger and a Beast as the AI did is the better option as only one of those dies in the process
(But yeah I also would have blocked Drove with the three remaining beasts, but as there is enough mana on the board I think blocking with the Birds is also a good option, I would say hand-dependant.)
