Specific examples would be helpful to the devs.

AI plays Quest for the Gravelord after 2 turn.
When I attacked with flying creatures (and this creatures is all creatures that I have) AI waited. And when I attack creatures with flying and not flying creature, AI plays Quest for the Gravelord and blocked this creature.
AI has posibility plays Quest for the Gravelord earlier and attacked me when my creatures already attacked and tapped.

I couldn't play my Basilisk Collar on my opponent's Keening Banshee. So I took control of it with Mark of Mutiny. At the end of my turn when control reverted, the artifact stayed on the creature and I was unable to reattach the Basilisk Collar to one of my creatures.

Did you post a bugged version or smt else happens I don't believe that I found so many mistakes.
Bugs under 1.20
1)(unless rules changed and I don't know about it)If you have in play a Land that comes in play with counters like Vivid Marsh and pay mana to cast a creature although you tap another land for the colored mana Vivid Marsh also taps and lose the counter no matter that I use it for (1).Even if you tap the land for the right mana (Vivid Marsh for Black) it still loses the counter.
2)Leonin Relic-Warder has wrongly trample.
3)Searing touch in the action menu and messages menu states wrongly that it deals 3 damage instead of 1.
4)I have Phyrexian Prowler and AI attacked with a shadow creature and 2 others but I wasn't allowed to block the non shadow creatures,see picture.I am not allowed to attack with it also.
5)I am not allowed to block Diregraf Ghoul with Snapsail Glider see pic.In fact I can't block it with nothing.(has wrongly shadow)?
6)I am not allowed to block with Keldon Marauders.
7)I am not allowed to block with Gibbering kami.
For call to the grave Phyrexian Prowler is a Zombie.
9)I am not allowed to block with Waning Worm.
10)I wasn't allowed to play Moment to Heroism nor attach Sickleslicer to my Steppe Lynx.
11)Hand of Honor is forced to attack each time.

Picture posted. I was able to block Puppeteer Clique with a Kitchen Finks. PC had flying and was equipped with Accorder's Shield. KF had nothing, etc.

Thanks guys, there is a really nasty bug with the way abilities are handled. Please disregard 1.20 for now, sorry for the oversight.

The gory details:
Currently we use a 64bit flag (each bit records whether the card has a specific ability) to store the abilities but in this version we improved the card script and added support for many additional card abilities in the engine and this increased the number of abilities to 100+...

Folks, it appears that Magarena is not removing a counter from Gemstone Mine when it is tapped for mana.

Otherwise, the new version seems to be working pretty well.... Thank you for putting all this together.

This is a result of the tweaked AI blocking options in 1.19. In 1.20b, we have made the AI consider more blocking options. Do let us know if you observe any more weak plays.

Tracked on our issues database @ http://code.google.com/p/magarena/issues/detail?id=97

beholder wasn't able to reproduce the problem, I'll give it a shot later.

Vivid Marsh and other Vivid lands are implemented as scripts in 1.20b and there was an unexpected interaction the scripted ability and the way mana abilities are selected when paying mana cost that lead to the bug. Previously, Vivid Marsh was implemented as tap add and tap, remove charge counter, add or or or , hence the bug did not occur. The new scripted Vivid Marsh has the last ability corrected as tap, remove charge counter, add one mana of any color.

Thanks, there is a bug in the message.

Phyrexian Prowler IS a Zombie according to the latest Oracle text http://gatherer.wizards.com/pages/Card/ ... seid=22029 Unfortunately the card image was never updated... Sorry for the confusion.

This is the critical "creatures getting the wrong abilities" bug due to the engine having 100+ abilities yet trying to represent all possible combinations using using only 64bits.

Thanks, a consequence of the "creatures getting the wrong abilities" bug. Kitchen Finks was getting its enters play ability treated as reach or something similar.

Thanks! There is an error in Gemstone Mine's script. It wrongly has the tap to add any mana ability in addition to its original ability.

Very often this situation appears: AI attack with creature/creatures, which will be destroy by my blockers.
For example, I attack with creature 3/3 with vigilance. AI has creature 2/3.
AI does not block, then AI go attack with creature 2/3 and I block by creature 3/3 with vigilance. In this result AI simply lose creature without any compensation.
If you want I can show screenshot of another situation.

Why such situation appears? Does AI not analyze power and toughness creatures, when go to attack?

I must say I have found nothing significant with the previous three versions of this software but with 1.20b I found I can no longer use the card aether vial. It offers no option to use the ability any more.
See the attached screen shot.

Thanks for the feedback, muaddib. I'm not exactly sure, the most recent tweak in 1.20b should have resolved this problem. We will need to reliable replicate this and do more testing.

If you could post a screenshot of a specific situation, the simpler the better, it would help us to create a test case to check for errant plays such as the one you describe above. Thanks!
