Collectible Card Game Headquarters

AI pumps an attacking Erg Raiders with a Wyluli Wolf in order to kill my blocking Rukh Egg... it doesn't realise that killing a Rukh Egg is a *bad* thing to do.

AI cast Mystic Retrieval with buyback targetting itself (the Mystic Retrieval).

The AI constantly targets fetch lands with spells like Spreading Seas or Evil Presence which is just a waste of a card.

If it really targets Mystic Retrieval with itself, than that's a bug, not AI issue since that should be impossible. Or maybe it targets a different Mystic Retrieval?

Invoke Prejudice (and likely In the Eye of Chaos et al.) are hilariously good against the computer. Had those cards instead imposed an additional cost this wouldn't have been the case, but as things stand the AI never thinks ahead and keeps tapping out.

Also if you hard-counter the computer's creature while Invoke Prejudice's trigger is on the stack, the computer will still pay when possible.

Dragon Tempest should make the AI more likely to caste Flying creatures in M1.

AI should bounce the opponent's lands with Reality Strobe when there are no other legal targets for it.

AI locks itself in an infinite loop of endlessly activating Opal Acrolith's ability.

Goblin Rimerunner is activated targeting one of my creatures, even though the Rimerunner is the only valid creature able to attack.

AI should block with all creatures with defender when Perimeter Captain is on the field

I attacked AI with a Spire Owl. AI cast Healing Salve to prevent the 1 damage it would have dealt, rather than just gaining 3 life.

AI recklessly casts Call to the Kindred instead of waiting for the most common creature type in its deck to be cast.

AI correctly pays for, but miscalculates how much damage will be dealt with Fireball. For example, the last time it cast Fireball, the game log stated 'Fireball deals 1 damage divided evenly (rounded down) to shteev and Glen Elendra Archmage'. The Archmage was a 1/1 at the time so I assume the AI was trying to deal 1 damage to it, but it ended up dealing 0 damage.

The computer sometimes runs into deathtouch blockers(for example: i have 2x 1/1 flying deathtouch, he has 2x 2/3 flying and attacks without a reason)
Also, the computer keeps burning Hornet's Nest, which isn't the wisest thing to do as we know. The same goes with attacking with non-flying creatures while this is on the field. I saw the AI attacking with Vastwood Gorgers and thus giving me 6 deathtouch flyers...

AI loves to block with an additional, unnesecary blocker.
An example:

I attacked with a 13/13, he blocked with a 2/2 and an Eldrazi Spawn.

I attacked with a 5/6, he blocked with a 6/6 and a 1/1.

I attacked with a 4/2 first strike, he blocks with a 2/1, 1/1 and a 2/2.


It doesn't happen always, but it did happen frequently.


Additionally, the AI simply loves to go all in in a attack, leaving himself wide open for a counter attack. In this case:
He attacked with all his creatures, leaving me with 1 life, but has no remaining blocker to defend against my (currently tapped) 10/10. He seems to believe that the last attack kill me.

He loves to go in an all out attack when he thinks he has won. So, he has a 3/3 unblockable and a 2/2 normal. I have 2 life. He attacks me with both, allowing me to block the 2/2 with my 5/5 lifelink and thus surviving.
