Requests for AI improvements

[Aswan jaguar]

Describe the Bug:
AI always activates Field Surgeon targetting my own creatures,doesn't get that it can prevent damage dealt to creature and not by creature.

Which card did behave improperly ?
AI-Field Surgeon

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
ML3-JUNE\13.V2

What exactly should be the correct behavior/interaction ?
AI has to target his own creatures to prevent damage dealt to them.

Are any other cards possibly affected by this bug ?

Fixed AI code for Field Surgeon.

i got a weird one here i have a savegame for it too and you can see that it could play alot of cards still but the AI starts to just give up? it draws then discards end of turn. it has land to play whatever in its hand. this is the new v2 dragons maze

[stassy]

Same request but on opposite behavior : most of the time AI won't cast anything until player do his first land or anything but land at the beginning of a round.

Describe the Bug:
AI has the bad behaviour to equip multiple times Leering Emblem.(AI has other spells to cast but spends all mana re-equipping Leering Emblem.

Which card did behave improperly ?
Leering Emblem

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
ML3-JUNE13.V2

What exactly should be the correct behavior/interaction ?
Equip only 1 time the same creature

Are any other cards possibly affected by this bug ?

Describe the Bug:
1- If AI has a Necrosavant in graveyard and a Necrosavant in play
AI will sac the Necrosavant in play to animate the other Necrosavant and do that again and again till all available multiple of 5 mana is spent no matter if AI has other cards to cast.
2- (having to do with above)AI won't sac another creature less valuable to animate Necrosavant.

Which card did behave improperly ?
Necrosavant -AI

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
ML3-JUNE.V2

What exactly should be the correct behavior/interaction ?
If AI has a Necrosavant in graveyard and a Necrosavant in play
AI should sac a creature with the less value(if it has one) or don't activate the ability at all-and always have summoning sickness.The only time that it would be valuable to sac the one for the other is if it is going to be destroyed and do that only 1 time.

Are any other cards possibly affected by this bug ?

As of OIv1, AI will play Ad Nauseam and reveal cards from its lib...until there is no card in lib, ad nauseam self damage and self milled

[HarlequinCasts]

AI never appears to interact with Battle of Wits even though it will lose the game the next turn. It will prioritize any other artifact/enchantment if it has removal. In the attached save, it Oblivion Ring 's a mana artifact instead of Battle of Wits.

Describe the Bug:
AI will sometimes activate Willow Priestess to put a faerie permanent in play from hand without having a faerie permanent in hand.(not a bug but bad play generally see below)

Which card did behave improperly ?
AI - Willow Priestess

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
ML3-ODYSSEY.V2

What exactly should be the correct behavior/interaction ?
Ideally AI uses that ability with or without having a faerie permanent in hand only when a card forces it to attack or block (or do something else when untapped?)causing a disadvantage.

Are any other cards possibly affected by this bug ?

SAVEGAME CORRUPTED

[stassy]

When Lurking Predators is in player bf, AI check player lib before casting any spell and will only cast something when it will be sure Lurking Predators won't favorably trigger and show a creature, how clever are you AI (if there are more than one Lurking Predators in play, it will even check how many time the player might bury the next top card in order to get a creature by looking for x card up to x Lurking Predators in player lib)

This make this card completely useless unless the player create a vise lockdown like condition because AI won't cast Lurking Predators either (worse than the Opal Acrolith syndrome).

[Gargaroz]

Well, as you know the AI will make his moves already knowing the immediate consequences, so this behaviour is predictable. And I don't think is fixable.

[Korath]

It might work to make the card do nothing if ai_is_speculating==1.

[Gargaroz]

I'll try this fix for both Lurking Predators and "hidden / opal enchantmens" from Urza's block.

[BAgate]

More a question. How does the AI pick a card at random? I just ask because several cards require you to name a card and then do something (ex. Cabal Therapy). You would think that the AI would sometimes get it wrong, but I have never seen the AI miss.

[stassy]

Because it seems hard to implement rng, most of these cards have fixed ai behavior (like Meddling Mage always picking the top library player card)
