Big 'Maybe' for me as well.
I respect the idea of statistics, and as such, if a tool like that were implemented, I would love to see these type of stats on the spreadsheet as more 'fun' data:
-Number/type of False Gods you faced with a deck (when you change the deck, your stats are erased, but otherwise, it could be provided in the trainer perhaps to make it easier for deck testers to research anti-FG strats)
-Number/type of cards won (Just a little bonus. This could be a recurring stat that would be nice to show off; "Oh, you think -YOU- won a lot of upped cards against Paradox? Well here..." etc.
-Oracle Spin stats (what elements are spun onto the most by you, what cards you win, average amount of electrum obtained on a daily basis - total amount of nymphs won from these spins?)
Just a big suggestion though. I could live without it, but I'm sure a lot of people would also like to see statistics on the game somewhere. ^^;
