Two of my friends were debating about Crystallization Phenomenon vs Immovable Tactic as well. One friend pointed out that Immovable was better, because the wording allowed you to take action 'before' anything was being destroyed, meanwhile CP could only be activated during a monster's destruction. I believe that they settled on Immovable, because Immovable would save your monster(s) meanwhile CP wouldn't?
