Requests for AI improvements

[Althuna]

oohh well, nevermind.

[Enchanteur]

The AI is very couard !
AI don't attack you, even if you have a 2/2 and AI have five 2/2.
AI always fear to make his dudes dies.

[Blackblade]

AI casts Crossway Vampire after combat.

[RanDomino]

The AI doesn't seem to understand how Skinshifter works.

[Gargaroz]

Skinshifter is a very complex card for the AI, since have 3 different abilities.

[stassy]

Or make like Planeswalker make it to use only one ability?

[Aswan jaguar]

You all know very well how important is especially in the first 1 to 5,6 turns not to loose a land drop and that it holds your game back if you are short of lands.
Even more important this is for our AI we all now has lots of limitations that can't be improved without knowledge of the code but what can be possibly improved are LANDS THAT CAUSE AI serious problems (missing 1st land-drop,land-drops in general and make his progress in the game a lot slower and so uncompetitive.

The last 3-4 weeks I have begun testing ALL lands and how AI deals with them.The test is not over yet, a lot of work is still needed but I wanted to give some results so Gargaroz and maybe Jatill who is back again can slowly fix them.
General notes about AI - Land problems AI will miss significantly less times the first land drop when it plays second/draws first.

- Even lands that don't cause AI to miss land drops have some issues and I have descriptions-notes next to "OK" that point out AI's bad use of them.

*I use the word "always" but in some cases it could mean most times.

[Gargaroz]

AJ, just a quick hint : the AI, when it's making it's decisions, try a lot of different combinations, but they're all "instant" combination, that will take in account immediate or short-timed bonuses.

Let's say we have a land called "Victory Vale" with this text "Victory Vale will come into play tapped. Victory vale comes into play with two "victory" conters on it. At the beginning of you upkeep, remove a victory counter from Victory Vale. When there's no counters on Victory Vale, you win this game".
The AI will probably never play this land at all, unless we "convince" it to do so.

So, please, focus your test on these kinds of lands. Stuff like painlands or SOM lands, or similar stuff are working for sure, as they give immediate or short term bonuses

[Gargaroz]

Added a little more AI for Skinshifter, but there are really too options for the AI to consider.
Also fixed values for Crossway Vampire.

[stassy]

Don't know if it's done in purpose, but AI will stop using Chalice of Life until 29 life, exactly before its morph into Chalice of Death and will no longer use it if its life number goes past this limit with other mean.

[stassy]

AI will still cast imprint card when there is no valid card to imprint in hand (eg. Chrome Mox)

[stassy]

AI tend to sacrifice the following mana generator artifact instead of just tapping them for mana :
Eye of Ramos
Heart of Ramos
Horn of Ramos
Tooth of Ramos
Skull of Ramos

[Gargaroz]

Improved AI for Chrome Mox and Ramos parts.

[Psychodabble]

AI doesn't understand Stuffy Doll. It will still play damage effects against it and will attack with its creatures despite the fact that it can only hurt itself. (examples: AI cast Lightning Bolt on Stuffy Doll, even with no chance to destroy it. AI attacks with all creatures despite Stuffy Doll and Energy Field in play.)

[Yggdrasil]

In fact it's the same with all indestructible creatures. AI just ignores this ability and tries to kill them like any other creature.
