Just my reflection... Maybe if I blessed the forest spirit, it would have gone differently, but from what I remember, I had 3 HP my last turn, and Bootza could have done 40 damage if he only PU his dragons. So.. I believe at the point of my 30 sec decision on what to bless, if I should bless etc... I calculated that if he didn't have any PU, I won, if he did, I loss.
He had 2 more, so I don't feel so bad about the move. I died to my draws, team water's well made deck and Bootza's solid play. It was over before my one strategic decision was even an option.
