- AI activated
Elvish Piper after declaring no blockers, instead of doing it first and using the 6/6 creature played (
Tidal Kraken) to block my
Juggernaut.
- AI used a +3/+3 instant on a creature before I declared my blockers instead of after, so I knew I had to block with my 0/1 plant instead of valuable creatures.
Edit : found another problem :
-When the AI reveals a creature card for "Quest from Ula's Temple" it doesn't put a quest counter on the enchantment. This happened in the challenge game of the same name. It revealed like 6 creatures in the match but still had 0 counters on it and never activated the ability to play krakens.
-
Recoup : the AI didn't play the targeted sorcery card from the graveyard. Then used flashback next turn and also didn't play it.
(note : everything I post are cards existing AI decks use. I haven't tried making a deck myself for the AI yet.)
- AI used "
Squirrel Nest" on a land it tapped to play it, when it had two untapped forests remaining afterwards.
- The "
Chain Lightning" challenge doesn't seem to work properly. It plays a turn 1 lightning on my bird pet then...plays no cards at all for the rest of the game aside from mountains. I assume the AI either doesn't know it can be used on players, or assumes it's bad play. (I have 30 life at start)
As is, the AI has 0% chance of winning, I peeked into a files and it plays a deck with only Chain Lightnings in it..which it cannot use on the player.
oh wow it played one when it had 7 in hand finally. And I had 4 untapped mountains so I was able to fire it back twice.
- The
Land's Edge deck isn't working properly either. It's playing mountains when it should be discarding all of them for a fast win. And it's doing it one land at a time when the spell allows discarding all 7 in hand at once. I don't know yet but I suspect this means once its hand is empty, newly drawn mountains get played instead of discarded...in other words this AI is also unable to win.
- AI played
All Hallow's Eve when it had zero creatures in its graveyard but I had two. Then didn't use its creatures to block the turn before they were coming back from the grave and took 11 combat damage for no reason at all.
- AI used
Armageddon when I had 3 creatures and it had none.
- The AI does not consider the effect of
Mana Flare when paying for its spells. It still taps 5 lands for a 5 mana creature then the rest gets wasted (and I assume it would take mana burn damage if I hadn't turned that off after the previous similar AI problem)
- AI played
Stasis on turn 2, with nothing tapped on my side and no way to pay for the upkeep so it was completely wasted.
- The AI had Circle of Protection : Red in play but consistently tapped out every turn to play weak creatures against my mono-red burn deck so it didn't get to use it even once.
- AI used
Unsummon on my Benlish hero with no enchantments, when I had a WIll-o the Wisp in play that had 5 enchantments on it and was 7/6. It was also enchanted by the AI's
Earthbind which might have caused it to think it's already neutralized? Even if not flying, a 7/6 regenerating creature with fear is more of a threat than a 1/1 banding.
- I had 4 life remaining. AI plays
Fireball with 10 untapped lands. Targets me, my
Samite Healer and my
Nettling Imp each for 2 damage instead of winning.
- AI tapped a land enchanted by
Psychic Venom (take 2 damage if land is tapped) when it had other lands available.
- AI played a second copy of pestilence when it already had one and having two provides no benefit. Tapped the land enchanted by phsychic venom for this, too. Not sure if they can even active the ability on pestilence, haven't seen it happen, though I admit killing my two 2/2s isn't the best deal ever.
I tried to build an ashen ghoul based deck for the AI but...
-AI doesn't recognize ashen ghoul, nether spirit and similar cards to be a good thing to discard...in particular for anvil of bogardan. Not sure if it recognizes
Squee goblin Nabob which another deck I built uses. AI is generally dumb at selecting what to keep and discard, does it actually evaluate the cards and keep the one that has the highest priority to get played? Or is it just random? From my observations it seems to discard
Corrupt whenever it can. It should at least prioritize cards that have flashback, madness, an ability to come back from the grave, and failing all that, the highest cost CREATURE.
-AI puts dumb things into the graveyard with
Entomb. I tried to be fail-safe and only include creatures that should do well in the graveyard, but it decided to bury a
Corrupt instead. I think it goes for the highest cost card, but doesn't make sure it's a creature?
-The AI should also equip their Skullclamps to creatures that return from the grave to draw extra cards even if it would "kill" the creature, including
Nether Shadow,
Ashen Ghoul,
Nether Traitor, etc if it doesn't have many cards in hand already (probably should not do it above 5 cards and definitely not if library size is low.)

-AI destroyed worship in the end combat phase after I didn't take any damage from the attack. If it did it two phases earlier I would have lost.
-I played
Heat Ray with
X=0 and the AI countered it with
Power Sink. (Yea I know people usually don't play spells with
X=0 but in this case I had a reason to, there was a
Veiled Sentry on their side and I wanted it to be 1/1, drafts can have interesting stuff happening)
-The AI enchanted my 1/1 creature with
Parasitic Bond, then killed it with
Sicken next turn.
11/06
-The AI recklessly plays all its creatures from its hand despite
Noetic Scales being in play, only to return them all to hand next turn and end up in a pretty bad situation.
11/07
-The AI in quest mode who plays and enchantress deck keeps playing enchantments and drawing cards even when it causes it to lose by decking itself out. It went through the last 20 or so cards in its library in two turns and actually lost the game on the second turn before ever getting a chance to attack me with the stuff it played. (
Argothian Enchantress and similar cards)
Game two it decked itself out in less than 8 turns without playing a threat, unlocking an achievement
(did anyone actually bothered to TEST the opponents in quest mode? There shouldn't be decks the AI cannot play properly and this isn't the first time...)
11/08
-The AI puts multiple copies of
Orcish Mine on the same land when playing the challenge deck in the homelands world that has many copies of that card. These should be played on different lands instead.
11/10
-AI used
Ostracize to make me discard
Blizzard Elemental, then attacked with its
Phyrexian Broodlings enchanted by
Brilliant Halo (3/4 total) when I had a 4/4 blocker. After it died, the AI used
Exhume to bring it back, giving me a free
Blizzard Elemental. Net result : AI spent 2 cards and returned one to hand to give me a free 5/5 flying creature and I lost nothing.
11/11
-AI killed itself 3 times in a draft game by tapping lands when I had
Manabarbs in play.
11/12
-AI keeps sacrificing a creature that returns itself to
Goblin Bombardment to deal infinite damage, but I have worship in play so I can't die. It should kill creatures in his case. (in this particular case, worship itself because it was animated) At the very least it stopped after a finite number of attempts of failing to deal the last 1 damage, nice. Tho did not do that 2 turns later, or at least it took longer than I was willing to wait before just conceding.
-AI played
Call to Arms when I had zero colored permanents in play so it was immediately destroyed. I doubt it was because I was playing a white deck and the AI knew it would help me more than them...
