Collectible Card Game Headquarters

Describe the Bug:
When Possibility Storm is in play and it's controller play another Possibility Storm with more Possibility Storms in library, then it is possible to play any number of Possibility Storms (screenshots included) or create infinite loop. AI won't pass on playing spells, and WILL create loop.

Which card did behave improperly ?
Possibility Storm

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink update 20 December 2014: Commanding 2014 Urzas, Duel

What exactly should be the correct behavior/interaction ?
Possibility Storm affected by another Possibility Storm should be actually exiled so it won't appear in the library again.

Are any other cards possibly affected by this bug ?

Curious. I wonder why the 2nd (and subsequent) Possibility Storm is getting triggered.

This is really strange... I added another check in 7555360, hopefully it won't triggers from stack anymore.

Still get an endless loop. What's more, the number of Possibility Storms in your deck doesn't matter. Triggers each time one is put in play and never ends.

Re-checked and it's not happening anymore. Seems fixed now.

Not happening in release either. fixed.
