I just recently added Chain Lightning to my Priestess deck on a lark, and it was HUGELY instrumental in helping me defeat the Beastmaster in a game last night. Elemental Wand + Chain Lightning = exceptional re-usable crowd-control.
Now, I'm not talking about theorycrafting, or the metagame, really, just principle. It is exactly the kind of spell that can swing the tide of battle in your favor, and, as a meta card, I think it really could warrant inclusion in just about every spellbook.
Thoughts? Opinions?
