* ChangeSpellTargets - Fix that AI don't go to endless loop.
if multiple permanents come to battlefield at the same time, they are aware now of each other. (e.g. useful for for Valakut, the Molten Pinnacle).
* Fixed a bug that abilities of sacrificed permanents did trigger if the spell they where sacrificed for triggered their triggered ability. (e.g. a Valakut sacrificed for a Scapeshift did still trigger if enough mountains where on the battlefield).
Some minor fixes to Valakut, the molten Pinnacle and Scapeshift (text, target handling, optionality).
