[partly confirmed]Rupture Spire-AI not playing any land.

Describe the Bug:
In the attached save, the AI seems to have drawn a bad hand; they're not playing any land, to the point where they have to discard cards they've drawn. However, if you look at their graveyard, you'll notice that they just discarded a forest, which they could have played...

Which card did behave improperly ?
I believe the cause of this is the Rupture Spire in their hand; presumably the AI intends to play it, realizes that it won't be able to pay its cost, then gives up without realizing that it could have played the forest.

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink Update 2014/05/06: Journey into Nyx, Sealed

What exactly should be the correct behavior/interaction ?
The AI should play land.

Are any other cards possibly affected by this bug ?
No idea! Possibly other lands with come-in-to-play triggers.

I confirm this bug but it happens Only if Rupture Spire is in hand and there are no other lands on the battlefield.
Unfortunately I have checked in the past a lot of lands and others are also very difficult for AI to handle and that results to not playing a land.Although things about some lands AI had problems before have now been greatly improved.

We don't know how to influence which land the AI considers playing. It picks a land to play, sees whether it'd be better off with it in play or not, then plays it or not; it won't go on to then consider a different land. Rupture Spire probably gets prioritized because it can generate any color of mana.

This also happens when AI has Kjeldoran Outpost (and other lands) in hand and no lands on bf. Probably also applies to the other Alliances lands from that cycle.

Figured I would toss Transguild Promenade on this list.
